Oily sludge is oily solid waste produced in the process of oil extraction, transportation, refining and oily sewage treatment. Oily sludge contains a lot of benzene series, toxic substances, etc. If oily sludge is not treated, it will not only pollute the environment, but also cause waste of resources.
KOSUN petroleum water-based mud drilling waste treatment system can recycle waste drilling fluid waste, reduce treatment costs, recover useful mud and water, realize resource utilization, avoid environmental pollution by waste, and comply with regulations Environmental discharge requirements for waste.
Necessity of Slurry Treatment for Slurry Balance Shield
During the drilling process of the mud, due to the continuous entry of drilling slag into the mud, the specific gravity, viscosity and sand content of the mud change, which cannot meet the requirements of mud performance, and must be treated or purified, mainly by solid-liquid Separation, the drilling slag in the mud is separated and discharged and then recycled.
There are two main methods of engineering construction mud purification: sedimentation tank and mechanical equipment. The current mainstream mud-water construction has abandoned the use of large natural settling tanks and switched to a combination of vibrating screen and cyclone equipment for construction. The KD series mud water treatment unit manufactured by our company is mainly used to purify mud, complete mud recovery and solid slag treatment.
Mud-water balance shield mud-water separation According to the difference in the structure of the mud-water tank and the control method of the mud pressure, the mud-water shield is divided into: direct control type and indirect control type.
Similar slurries are also used in diaphragm wall operations (dual milling) and cast-in-place piles (rotary drilling and punching equipment).

Oilfield drilling mud is a working fluid that lubricates, cools, protects arms, transmits drilling cuttings and balances bottom pressure during oilfield drilling. Drilling waste mud consists of a small amount of mud discharged during drilling and a large amount of mud discharged after completion. The main components are bentonite, drilling cuttings, water and various chemical additives. Because the waste mud contains a variety of toxic and harmful pollutants such as alkali, salt, oil, etc., it is difficult to deal with, so oily sewage and dirty oil are called the three major public hazards in oil fields. With the provisions of the national environmental protection law and the enhancement of people’s awareness of environmental protection, the petroleum industry has stepped up scientific research on elimination, utilization and resource recycling.
During oil drilling, the use of drilling mud treatments is frequently involved. Untreated sludge can have serious environmental impacts if it is not treated effectively. Relevant practitioners need to properly implement various drilling mud measures and optimize scientific and technical means, so as to effectively improve the quality of oilfield mud treatment. Therefore, in the process of oil drilling, it is necessary to recycle the mud generated during the drilling process to ensure the smooth progress of the drilling work and the engineering quality of the drilling construction.
KOSUN’s mud zero discharge equipment is suitable for mud treatment in medium and large construction sites. The advantages of this model are the large processing capacity, the low moisture content of the mud cake, and the high degree of automation. The filter cake can be accumulated for a certain period of time, which improves work efficiency and reduces costs.
Drilling Mud Shale Shaker Installation Instructions Usually the drilling fluid shaker is installed on the first mud tank. There will be a positioning block at the location to help users confirm the location and distance, and the top of the tank where the shale shaker bin is located will also have an opening the size of a screen bed to receive the treated clean mud. The mud tank should be placed on a flat and clean ground to minimize the impact of the external environment on the performance of the shale shaker. During transportation or transshipment, it is not advisable to install the screen on the screen box to avoid damage to the screen due to collision, which will affect the use. The transport locking device should always be in a tightly closed state. Before use after installation, the transport locking device should be removed to ensure the normal operation of the shale shaker. During the installation process, read the installation instructions and follow the corresponding constraints to complete the installation.

In the sludge dewatering of farms, sludge dewatering equipment is the core and important equipment. The principle of sludge dewatering equipment in farms is the same as that of sludge dewatering equipment in other industries. There are many sludge dewatering equipment in farms. At present, domestic sludge treatment equipment includes centrifuges, plate and frame filter presses, chamber filter presses, diaphragm filter presses, and high-pressure sludge dryers. Different sludge treatment equipment the moisture content after dehydration is different.
The characteristics of farm pollution are high-concentration organic sewage sludge, high content of suspended solids and ammonia nitrogen, and high content of organic matter and microorganisms. The sewage sludge of the breeding site has the characteristics of three highs. The organic matter concentration COD is as high as 3000-12000mg/1, the ammonia nitrogen content is as high as 800-2200mg/1, the suspended matter is dozens of times more than SS, the color is deep, and it contains a lot of bacteria, organic phosphorus, Heavy metals, residual chemicals and other hazardous substances.
It has been proved by experiments that the effect of using the horizontal screw decanting centrifuge in the sludge dewatering process of the farm is better than that of other sludge dewatering equipment. The centrifuge adopts the principle of centrifugation. After being treated by the centrifuge, the water content of the sludge cake is low, the equipment covers a small area, and the capital construction cost is low, the device has the advantages of compact structure and so on.
Recently, KOSUN successfully supplied a set of processing system for efficient cleaning of coal slime and slag for Shaanxi Coal Group, and sent it to the customer’s project site to complete the installation and commissioning.
