Cleaning sewage treatment equipment

1Washing wastewaterpollution characteristics

Washing wastewater, mainly composed of soap, oil, synthetic detergents, cleaning agents, as well as a small amount of harmful substances such as bacteria, coliforms, viruses, etc., has become an important source of water pollution. After washing wastewater is discharged into water bodies, it consumes dissolved oxygen and has slight toxicity to aquatic organisms, which can cause fish deformities. The phosphate solvents contained in it can cause eutrophication of the water body. The concentration of organic matter in washing wastewater varies greatly, with high turbidity and a BOD/COD ratio of around 0.45, indicating good biodegradability. The effective ingredients of detergent are surfactants and detergents, in addition to various auxiliary ingredients such as bleach. Surfactants can be classified into three types based on their molecular configuration and functional groups: cationic, anionic, and nonionic.

IIWashing wastewater treatmentworkmanship

The physical and chemical treatment methods for detergent wastewater include coagulation, adsorption, air flotation, oxidation, membrane filtration, etc. Biological treatment methods for detergent wastewater: hydrolysis, efficient anaerobic treatment, biological contact oxidation SBR、 Biological filters, etc.

Process flow: Washing wastewater - grid - regulating tank - coagulation sedimentation tank - hydrolysis acidification tank - contact oxidation tank - sedimentation tank - sludge tank - filter press - sludge transportation - filtration - standard discharge.

IIIWashing wastewater treatment equipmentcharacteristic

1. Strong ability to withstand impact loads, with a uniform retention time of at least 6 hours using the touch oxidation method;

2. Having the ability to remove nitrogen and phosphorus, and being able to treat industrial wastewater, daily sewage, and urban sewage through the structure of regulating equipment;

3. The fillers in the touch oxidation tank are mostly composite soft fillers, which are lightweight, high-strength, and have stable physical and chemical properties. They have a large surface area and strong biofilm adhesion, resulting in high contact efficiency between sewage and biofilm;

4. Using an aerator for air blowing aeration in the touch oxidation tank, the fiber bundles are continuously floated, the aeration is uniform, the microorganisms grow and mature, and it has the characteristics of activated sludge process;

5. The effluent quality is stable, the sludge output is low, and it is easy to handle;

6. Submersible pumps can be installed in equipment to reduce project costs;

7. The equipment can be installed on the ground or buried underground. When buried underground, the upper cover can be used for beautification, resulting in less land occupation and fewer above ground structures in the factory area;

8. Easy to achieve automatic control and simple point operation;

9. The device can be connected to a car to make a mobile washing wastewater treatment device.

4、 Scope of application of integrated washing wastewater treatment equipment

Suitable for car wash plants, cleaning plants, residential areas, places where washing products and materials are used, etc. There are these scenarios: ① factories, mines, schools, tourist attractions, scenic spots; ② Hotels, restaurants, sanatoriums, hospitals; ③ Residential communities, villages, and towns; Stations, flights, seaports, and ships; ④ Various industrial wastewater similar to domestic wastewater, such as organic wastewater treatment in industries such as textiles, beer, papermaking, leather making, food, and chemical engineering; ⑤ The integrated sewage treatment equipment is suitable for domestic sewage treatment in residential areas, restaurants, hotels, nursing homes, schools, mines, factories, slaughterhouses, and similar industrial sewage treatment. Summarize the operational achievements and engineering practices of domestic sewage treatment facilities.

5、 Washing wastewater treatment equipment brings economic benefits to customers

The washing treatment equipment has these advantages: 1. Low requirements for incoming water quality: the incoming water quality only requires a pH value of 6-9; 2. Low engineering investment: Due to advanced technology and significantly reduced processing equipment, investment has decreased; 3. Small footprint: fewer equipment, compact arrangement, and smaller area; 4. Low operating costs: Due to the unique process, it greatly saves operating costs; 5. Good effluent effect: The effluent can meet national standards.
