A kind of multistage anti-clogging plug filtration unit
Technical field
The present invention relates to filtration unit, particularly relate to a kind of multistage anti-clogging plug filtration unit.
Background technology
Sewage purification, channel cleanout, rainwater collecting processes all need to be purified by liquid. Water float thing is easily removed, and in water suspended substance compare be difficult to remove, the method for general settling tank or filtration purifies. Settling tank is a kind of structures that application precipitating action removes suspended substance in water, widely uses in the treatment of waste water. But settling tank purification speed is relatively slow, when treatment capacity is bigger, it is necessary to build large-scale structures, floor space is big, and cost is higher, and transient stay phenomenon easily occurs. Transient stay refers to that the residence time of part water is less than the design residence time, flows out outside pond very soon, can not get abundant precipitation; Then the residence time is greater than the design residence time to another part, even occurs decreasing the useful volume of settling tank in the slough that current cannot do not stagnated dynamicly substantially. Filtering after referring to that fluid enters the filter cylinder being equipped with certain specification filter screen, its impurity is stopped, cleaning filtrate is then discharged by filter outlet. Filter succinct rapidly, but when adopting general filter method, in liquid, impurity buildups is on the surface of filter screen, is easy to blocking filter screen.
