Problems solved by technology

And because the specific gravity of the filter material is slightly larger than that of water, it is also easy to backwash
[0003] However, the fiber ball filter also has its own disadvantages: after the fiber ball filter material has been used for a period of time, the fiber ball filter needs to be backwashed to clean it, because too much viscous oil has accumulated on the surface of the fiber ball. If it is washed, it cannot be cleaned thoroughly, especially after being affected by the sludge with high oil content in the middle, the filter material interception ability will decrease, and the filter material must be replaced, and the replaced filter material will be thrown away directly. The use cost of the filter device too high

Abstract

An asymmetric fiber filter mainly comprises a tank, a support, a motor, a filter unit, an exhaust pipe, a water inlet pipe and a water outlet pipe, wherein the cylindrical tank is fixed on the support, the motor is arranged at the top of the tank, the exhaust pipe is fixed on the inner side wall of the tank, the water inlet pipe extends deeply into the tank and is connected with a water inlet valve and a back wash drain valve, and the water outlet pipe is located at the bottom of the tank and is connected with a water outlet valve, a back wash water inlet valve and a vent nozzle. The filter is simple in structure, lower in cost and wide in application range, and the filter unit is flexibly arranged.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to an asymmetric fiber filter. Background technique [0002] The fiber ball filter uses fiber balls bound by fiber filaments as the filter medium. The filter material has a large specific surface area and porosity to contact and coagulate with the suspended particles in the water, so that the suspended particles in the water adhere and retain them in the filter material layer. Because the filter material is flexible and the gap is variable, due to the working pressure and the weight of the filter material during filtration, an ideal distribution state of the filter material is formed, and the filtering ability of the filter material is fully exerted. And because the specific gravity of the filter material is slightly larger than that of water, it is also easy to backwash. [0003] However, the fiber ball filter also has its own disadvantages: after the fiber ball filter material has...
