Drilling Mud Zero Discharge Treatment Process

Brife introduction of drilling mud zero discharge treatment process:

1.Collection Unit. Through the solid control equipment, drilling waste mud enter into the screw conveyor, while adding water for dilution and mixing. Then through screw conveyor, the mud enter into the sand and gravel separation & washing and stirring device, after stirring, washing and spiral separation, a large number of inorganic particles, small rocks, cuttings can be separated from the drilling mud, which reduced the influences of type of material on the follow-up treatment. So that the abandoned mud can maintain the good liquidity. After the separation, the mud lifting into the slurry storage tank by the mud pump, while adding treatment chemicals, after stirring and mixing reaction, the mud lifting into the second processing unit the pump.

2.Solid-liquid separation unit. In order to reduce the moisture content and the pollutants of the mud cake, it is indispensable to add the treatment chemicals and the multiple stirring and washing. After the pharmaceutical treatment and repeated mixing and washing, the contaminants contained in the mud are washed into the water. If there is petroleum pollutant, it needs to be treated by the oil removal device first, and then the oil is recovered. The de-oiling mud is sent to the centrifugal extension by the pump for mud and water separation, and the solid matter in the mud can be discharged after the separation. The separated water enters the collection tank and then pumped by the pump to the third treatment unit.

3.Wastewater treatment unit. After centrifugation, the content of suspended solids in the water is relatively high. Through the flotation and filtration system, the suspended solids contained in the water are removed, reducing the organic content in the waste water and then enter the reverse osmosis system for concentration. Reverse osmosis out of the standard wastewater into the reuse water tank, pump back to use for the production. A small amount of concentrated liquid can also be treated by evaporation crystallization, salt can be sold to salt chemical manufacturers, turning waste into treasure.

The above is the whole drilling Mud Zero Discharge Treatment Process.

Strategy to Manage Solid Waste

The Government are committed to sustaining a healthy environment and a vibrant economy. Consistent with this commitment, there has been a fundamental shift in the way we view solid waste. It is now recognized that solid waste is a resource that can result in the creation of jobs through cost effective and environmentally responsible management. The Strategy to Manage Solid Waste will include these benefits:

Bans on the disposal of beverage containers, corrugated cardboard, newsprint, scrap tires, used oil, lead-acid batteries, waste paint, automotive antifreeze, glass food containers, steel/tin cans, selected plastics and compostable organic materials.

Expansion of the current deposit/refund system on beer and liquor bottles to include all beverage containers with the exception of milk. Milk containers will be recycled through province-wide collection programs.

The number of active landfills will be reduced by approximately 75 percent. Currently, there are 40 active landfills in the Province. All landfills will have to meet the Department of the Environment’s new stricter guidelines to prevent leachate and other problems associated with the current variety.

In order to ensure that cost increases are minimized, municipal units will be encouraged to cooperate on a regional scale. It is recommended seven solid waste resource management regions be established.

The Strategy will involve diversion of 60 to 70 percent of household hazardous waste from disposal facilities.

In a consumer society, most commodities, once no longer used for their intended purpose, have traditionally been discarded. The implications of this “throw away” mentality are profound. In recent years, people have begun to recognize these implications and have taken aggressive action to change their practices and attitudes towards waste.

Reducing the amount of waste we generate, identifying opportunities for the recovery of valuable resources, encouraging the development and commercialization of new technologies, and taking necessary action to secure a sustainable future are among the challenges we face today and in the years ahead.

Drilling Mud Treatment and Disposal Methods

With the continuous improvement of environmental protection laws and regulations, people’s awareness of environmental protection has been gradually enhanced. Drilling mud treatment and disposal during drilling has become the focus problem in the drilling industry. The purpose of drilling mud treatment and disposal is to reduce environmental pollution and to find a economically and environmentally methods.

There are many existing drilling mud treatment and disposal methods, but each method has its scope of application. It should be selected according to the geologic environment, hydrology, soil, drilling fluid composition and economy of the oil and gas field. Throughout the processing methods at home and abroad, drilling mud treatment and disposal methods including the following categories:

(1) Direct discharge method

Direct discharge method mainly applied to conventional freshwater drilling fluid.

(2) Landfill method

This is a more primitive approach and is mainly suitable for general freshwater-based drilling fluids.

(3) Dehydration method

This method used the chemical flocculation, sedimentation and mechanical separation and other strengthening measures to make the waste drilling fluid in the solid-liquid two-phase separation.

(4) Pit seal

This method is a special landfill method. It is recommended for toxic waste drilling fluid treatment and disposal.

(5) Annular space treatment method

The waste drilling fluid is injected through the borehole into the formation or safety formation of the oil and gas.

(6) Soil biodegradation method

Sprinkle the waste drilling fluid directly onto the soil surface and mix it into the soil with a soil tillage machine. This method is mainly applicable to the processing of freshwater drilling fluids and some oil-based drilling fluids that are easily biodegradable.

(7) Land cultivation method

Land cultivation practices require an open and relatively flat land and it should have surface conditions that prevent erosion.

(8) Closed loop system

The system is equipped with high-efficiency solid-control equipment that uses rigorous management tools to reduce the amount of fluid-borne waste discharged while drilling and emit only a certain amount of wet solids for land, sea and virtually all non-gaseous Dispersed phase drilling fluid system. Effluent wet-solid phase can be buried in-situ, diluted in land, paved, filled or centralized, and the liquid phase recycled and reused, which not only reduces the cost of mud treatment but also saves water resources.

 (9) Solid-liquid separation method

Solid-liquid separation technology is the solid-liquid waste drilling fluid separation, the discharge of liquid standards, solid-phase buried or reprocessing.

(10) Curing method

This method is add curing agent to the waste drilling fluid to make it solidified into soil-like solid material, and then landfill or used as building materials. (Editor:Kosun Lily.Wang)

Sewage treatment technology is facing new changes

Sewage treatment technology is facing new changes

Compared with the traditional sewage treatment plant, the concept of sewage treatment plant proposed four new goals, namely: sustainable water quality, energy recovery, resource recycling, environment-friendly.

Sewage treatment
Sewage treatment

After 30 years of rapid development, China’s urban sewage treatment has made great achievements. But along the way, there are some hidden dangers in China’s sewage treatment business. Due to the lack of sustainable development concept, leading to the industry’s shortsighted, extensive, chaotic and even inferior. China’s sewage treatment project urgently needs to base itself on national conditions and carry out a systematic exploration for the future. The company is located in:

Recalling the course of development over the past 100 years, sewage treatment has made tremendous contributions to improving the living environment and promoting the progress of human civilization. The activated sludge method invented in 1912, long-term and effective to curb the discharge of water pollutants, still plays an important role in the sewage treatment system. In the 1960s, the United States put forward the concept of “advanced waterworks in the 21st century” with advanced thinking. That is, raising the standard of sewage treatment to drinking water standard has a profound impact on the development of the industry.

As of 2013, China has built and put into operation more than 3,500 sewage treatment plants at the county level and above, with a total daily processing capacity of 140 million cubic meters, playing a key role in deterring the intensification of water pollution.

Sewage treatment is in a period of major changes, urban sewage treatment plants will be reduced from pure pollutants into resources, energy plants, related policies, standards, technologies, practices are widely and profoundly changed. And these are the new directions that China must pay attention to in the future development of sewage treatment.

China Sewage Treatment Concept Factory is not the focus of the general sense of the project, demonstration projects, more should be seen as China’s sewage treatment business under the current opportunities and challenges for the future to a systematic exploration. (Editor:Kosun Lily.Wang)
