What are the applications of fully automatic centrifugal separation filters in the environmental pro
The fully automatic centrifugal separation filter relies on high-speed centrifugal force to complete solid-liquid separation. The whole machine can automatically feed, filter, discharge, clean, and operate continuously in a closed environment, reducing manual intervention. It is widely used in environmental protection conditions such as municipal sewage, various industrial wastewater, sludge reduction, hazardous waste disposal, water restoration, and waste liquid resource recovery. It is the core process equipment for wastewater pretreatment, sludge dewatering, and solid slag separation.
1、 Municipal sewage treatment field
1. Municipal sludge concentration and dewatering
Municipal biochemical residual sludge and primary sedimentation sludge are separated into sludge and water through centrifugal filtration, reducing sludge moisture content, decreasing sludge volume, and lowering subsequent transportation, landfill, and incineration disposal costs; Fully automatic slag discharge, suitable for 24-hour continuous and stable operation of sewage treatment plants, closed operation to reduce odor overflow.
2. Removal of suspended solids in sewage pretreatment
Rapid separation of high suspended solids, sand and gravel, and impurities in the incoming water reduces the load on subsequent biochemical tanks and pressure filtration equipment, protects the back-end membrane components, and reduces chemical consumption.
3. Dredging and silt treatment of rivers/lakes
Dredging mud and sediment from rivers and lakes, quickly achieving separation of mud and water, dewatering and reducing the volume of sludge, and ensuring that the supernatant meets the standard and flows back into the river, reducing the amount of sludge transported outside, used in black and odorous water treatment projects.
2、 Various types of industrial wastewater treatment
1. Chemical industry and chemical wastewater
Processing wastewater from dyes, pigments, resins, and intermediates, separating reaction residues and crystalline salt residues; Suitable for high salt and partially acidic and alkaline corrosive wastewater, as a front-end solid-liquid separation unit of zero discharge (ZLD) system, to reduce the load of subsequent evaporation system.
2. Electroplating and surface treatment wastewater
Separate heavy metal hydroxide sludge and separate heavy metal sludge such as nickel, copper, and zinc from wastewater; The filtrate can be further processed and reused, and the sludge can be disposed of as hazardous waste to reduce the risk of heavy metal emissions.
3. Petroleum and petrochemical, oily wastewater and sludge disposal
Processing oily sludge and tank bottom sediment from refineries and oil and gas fields; It can achieve three-phase separation of oil water solid, recover usable oil products, and reduce sludge dewatering and hazardous waste generation, achieving a balance between resource recovery and pollution control.
4. Coating and spraying wastewater
Process water curtain spray painting wastewater, efficiently separate paint residue and paint suspension, and recycle the treated water body for the water curtain system to reduce wastewater discharge. The paint residue is automatically discharged and collected, avoiding manual slag removal.
5. Mining and metallurgical beneficiation wastewater
Tailings water and slurry from mineral processing are separated to achieve tailings dewatering. The supernatant water is recycled and reused in the mineral processing process to reduce water resource consumption and lower tailings pond pressure.
3、 Hazardous and solid waste disposal sector
1. Dehydration of hazardous waste sludge
Chemical hazardous waste sludge, smelting sludge, waste catalyst slurry, fully automatic closed filtration dewatering, reducing the weight and volume of hazardous waste sludge, directly reducing the cost of hazardous waste disposal; A sealed structure prevents the volatilization and leakage of toxic and harmful exhaust gases, improving the working environment.
2. Recycling and resource utilization of waste liquid
Solid slag separation is carried out on waste cutting fluid, waste lubricating oil, and cleaning waste liquid to remove metal debris and oil sludge impurities. After filtration and purification, some of the waste liquid can be recycled to reduce hazardous waste production and achieve cost reduction and efficiency improvement.
4、 Environmental protection management of agriculture, animal husbandry, and livestock
Pre treatment of livestock and poultry manure and slaughter wastewater, separation of manure residue and suspended solids, significantly reducing influent COD, total phosphorus, and total solids, and alleviating subsequent anaerobic and biochemical treatment pressure; The separated solid manure residue can be further processed into organic fertilizer raw materials to achieve resource utilization.
5、 Comprehensive wastewater treatment in industrial parks
Comprehensive wastewater pretreatment in industrial parks involves rapid separation of large amounts of suspended solids and reaction precipitates in mixed wastewater, ensuring stable operation of subsequent biochemical and deep treatment processes; The equipment has a high degree of automation and is suitable for continuous processing of large flow in the park.
6、 Other segmented environmental protection scenarios
1. Papermaking wastewater: Separate pulp fibers and filler residue, recover fibers, and recycle the treated water for reuse;
2. Lithium battery new energy wastewater: treat lithium battery production wastewater, separate lithium salt waste residue and grinding slurry waste residue, and adapt to high salt corrosion conditions;
3. Emergency environmental response: rapid solid-liquid emergency treatment of sudden leaks and accident sewage, and rapid removal of suspended pollutants in water.
