Described reverse stream pipe below is provided with deposit cavity, and described deposit cavity is communicated with described return line, and described deposit cavity below is provided with splash pan, leaves the gap between deposit cavity and the splash pan;
Described reactor body bottom is provided with mud discharging mouth.
Equipment for separating liquid from solid described in the utility model can be designed to U-shaped or other shape, but most preferably return line is socketed on the reverse stream pipe outside, the described deposit cavity of the inner formation of return line of described reverse stream pipe below.
Described splash pan also can be used as guiding device simultaneously, when waste water and air when reactor bottom enters, stop in waste water and the air admission equipment for separating liquid from solid, thereby the muddy water of guaranteeing the equipment for separating liquid from solid the inside separates fully, the timely reuse of mud after the separation, guarantee that waste water stops the regular hour in reactor body, remove organic purpose to reach.Described splash pan is preferably the back taper traverse baffle.
In order to make in the reactor gas distribution even, reactor inner chamber bottom preferably is provided with distribution device, and distribution device connects the compressed air inlet.
Further, be provided with one or more thief holes in the middle part of the described reactor body.
Further again, described reactor body top is provided with tensimeter.
Described bioreactor for sewage treatment is worked as follows:
1, sludge acclimatization: active sludge is put into the inner chamber of described reactor, behind the vexed certain hour that exposes to the sun, adds certain sewage and a certain proportion of nutritive substance and tame cultivation, treat that mud possesses certain activity after, carry out the continuity bio-oxidation and handle.
2, pressure biological respinse: sewage is squeezed into the reactor inner chamber by pump by certain flow, behind the aerated reaction certain hour, overflow to the equipment for separating liquid from solid of described reactor body inside, after separating fully, mud flows automatically to outside reactor inner chamber from the equipment for separating liquid from solid bottom, carry out circulating reaction, supernatant liquor flows out from the water outlet that is arranged on reactor top.The regular simultaneously excess sludge in mud discharging mouth eliminating reactor.
Bioreactor for sewage treatment described in the utility model has reduced the handling equipment for offspring necessaries of conventional compression biochemical method, adopt built-in equipment for separating liquid from solid to carry out liquid-solid separation automatically, save the post precipitation processing, simplified technological process apparatus, reduced running cost.
