Abstract

The invention provides a filter tank. The filter tank comprises: a tank body, which is used for accommodating filtered clear water, wherein a water outlet part for discharging water is arranged on the tank wall of the tank body; a filtering device, which is arranged in the tank body and is used for filtering sewage; and a pipeline system, which respectively communicates with a sewage source and the filtering device, wherein when the pipeline system is in a first mode, the pipeline system conveys sewage to the filtering device for filtering, and when the pipeline system is in a second mode, a siphon effect is formed, and the clear water in the tank body is used for backwashing the filtering device. The filter tank provided by the invention has the advantages of simple structure and few control parts, and can realize the two functions of automatic circulating filtration and automatic backwashing. In a water treatment system, other types of filter tanks can be replaced by the filter tank provided by the invention, the complexity of the sewage treatment system is reduced, and maintenance is convenient.

Description

technical field [0001] The invention relates to the technical field of water filtering equipment, in particular to a filter tank. Background technique [0002] At present, urban sewage treatment stations generally only adopt the process of primary pretreatment and secondary biochemical treatment, mainly to remove most suspended solids and organic pollutants in sewage, but biochemical treatment and coagulation sedimentation cannot remove some fine suspended particles and colloids Substances, so filters are commonly used as a tertiary treatment method. [0003] The filter can effectively remove suspended solids in water and reduce turbidity. Existing ordinary fast filters need to be equipped with flushing equipment such as water pumps, electric valves and fans, and the structure is relatively complicated; gravity-type valveless filters rely on hydraulic automatic control, and the structure is also very complicated; siphon filters need to be equipped with vacuum siphons The s...
