Name: Air floating filter machine

details

　　Air-floating filter integrated machine, also known as air-floating filter integrated machine, is a kind of filter that collects air, floats, filters and adsorbs. It is mainly suitable for treating all kinds of wastewater with similar floc specific gravity to water after reaction. It has a good effect on the separation of oil and water, the removal of suspended solids, COD and BOD. Widely used in machinery, chemical, textile, transportation, food and other industries, especially suitable for oilfield drilling wastewater, oilfield refilling water, refinery wastewater treatment. The machine has the characteristics of convenient transportation, simple operation and good treatment effect.

　　The main processing technology of the air flotation filter integrated machine adopts physical and chemical methods. The traditional mature processes such as chemical method, air floatation method and filtration adsorption method are designed by organic combination. The utility model has the advantages of simple and reasonable process, wide adaptability, compact structure, convenient transportation and installation, simple operation, stable and reliable performance. For the separation of oil and water, the removal of suspended solids, COD and BOD has a good effect. Generally, the wastewater can reach the discharge standard after being treated. The whole device of the air flotation and sedimentation machine is composed of a sewage pump, a metering device, a dosing tank, a reaction tank, an air flotation tank, an air flotation system, a sand filter, an activated carbon adsorption column and an electric control system, and the combination is 10 t/h or less on the same base. , 10t / h or more for the convenience of transportation from the parts to the site assembled into a whole. When the whole device is adjusted to normal operation, it can be basically in the automatic running state, and the operation is convenient.

　　The working principle of the air-floating filter integrated air-floating zone is to form a saturated dissolved gas carrier in the dissolved gas tank under a certain pressure (0.35~0.45Mpa), and obtain a large amount of the compressed gas carrier in the dissolved gas tank through the release device. The fine bubbles quickly adhere to the flowing particles in the water, the emulsified oil, the bath and the coagulated reaction flocs, causing the floc to have a specific gravity smaller than that of the water, and is forced to float on the water surface to obtain solid-liquid separation. In the process combination of complex and difficult wastewater treatment, the air flotation treatment is accompanied by the aeration phenomenon, which reduces the surface activity and organic concentration, so that the oxygen consumption is greatly reduced, and the further purification of the wastewater is promoted. Provides water quality that is conducive to compliance.

　　The air-floating filter unit can increase the water production per unit area by 4~5 times, and the floor space can be reduced by 70%. It can adapt to the sewage quality of different strengths. The purification residence time is shortened by 80%, and slagging is convenient. The slag body has low water content, and the sewage treatment SS has strong effect. The investment is low, the power consumption is low, and the coagulant dosage is high.
