Description
Technical field
The present invention relates to Environmental-protecting treater technical field, divides filter and point filter side more particularly to a kind of star-like solid-liquid
Method.
Background technology
As the continuous progress of the mankind and the high speed development of social productive forces, water pollution problems getting worse, water resource are tight
Lack and increasingly highlight.To make full use of the source of water, National Development and Reform Committee, the portion that builds, Chinese Ministry of Environmental Protection's joint appearance are lived《Ten, water》, it is desirable to it is universal
Urban wastewater treatment firm Effluent criteria in area's in all parts of the country is improved, effluent quality requirement reaches《Urban wastewater treatment firm pollutant is arranged
Put standard》（GB18918-2002）One-level A standards.And existing urban wastewater treatment firm overwhelming majority effluent quality can only achieve
One-level B standard, want to reach one-level A standards, it is necessary to carry out existing urban wastewater treatment firm upgrading, technological innovation, increase
The technology path of plus depth processing.
Conventional depth-type filtration technique has two kinds of rotary disc filter, active sand filter, wherein active sand filtering technique
Although good filtration effect and stable effluent quality, investment cost is larger, and filter tank quantity is more, and trouble point is more, causes construction week
Phase is long；Rotating disk filtering technique design cycle and short construction period, but not enough save in use.
The content of the invention
The technical problems to be solved by the invention be how the processing sewage of efficient energy-saving, overcome prior art lack
Point, there is provided a kind of star-like solid-liquid divides filter.
In order to solve the above technical problems, the present invention provides：
A kind of star-like solid-liquid divides filter, including tank, is provided with star-like formula water-distributing device of transferring shares inside the tank, described star-like turn
Water spraying mechanism is provided with above drum-type water-distributing device；
The star-like rotary drum water-distributing device include support, be connected with holder pivots rotation framework, be covered in rotation framework on
Filter membrane and the rotary drum motor of frame member is rotated for driving, the support towards the one end for rotating framework offer into
Mouthful；
The support is provided with flushing water collecting groove positioned at lower portion is rotated, and the notch for rinsing water collecting groove is set upward,
And the described one end of flushing water collecting groove away from entrance is provided with opening；
The tank includes intake chamber, effluent collection groove and sewage collecting tank, and one end of the tank towards entrance offers
