The invention relates to a wastewater solid-liquid separator and a separation method thereof, which belongs to the technical field of sewage treatment. A plurality of multi-layered filter elements are arranged in a solid-liquid separation cabinet, the four sidewalls of each multi-layered filter element are three screens and a discharge door, and the bottom plate is a bottom plate screen; an influent water distribution pipe is arranged on the top of each multi-layered filter element; a water collection area is under each multi-layered filter element; the water collection areas are connected to anaerobic water distribution pipes through a water collection pipe, and the anaerobic water distribution pipes are mounted in upflow anaerobic reaction tanks; the tops of the upflow anaerobic reaction tanks are connected to a sludge-water separation tank; sludge funnels are arranged at the joints between the bottom of the sludge-water separation tank and the upflow anaerobic reaction tanks; the sludge-water separation tank is also provided with sludge outlet pipes, and the sludge outlet pipes are connected to a sludge suction pump; and the top of the sludge-water separation tank is also provided with a water outlet. The invention comprehensively solves sludge and colloidal substances in the pretreatment of piggery wastewater, water which finally comes out of a water outlet pipe does not carry sludge, little colloid or even no colloid exits in the water, and thereby the difficulty of subsequent sewage treatment is decreased.
Description
technical field [0001] The invention relates to a waste water solid-liquid separation device and a separation method thereof, belonging to the technical field of sewage treatment. Background technique [0002] At present, the solid-liquid separation of pig farm wastewater mostly uses mechanical (or vibrating) solid-liquid separators for rough separation. The separated water has obvious characteristics: the effluent is turbid, the suspension is high, and most of it is insoluble and colloid. state. Wastewater in this state enters the subsequent biochemical system, and after anaerobic fermentation, its jelly part is separated from the water and suspended in the water in the form of small particles, and the amount of suspended solids in the anaerobic effluent is large. Subsequent dosing is difficult to precipitate; if a belt filter press is used, the amount of recoil water brought by the flushing of the filter cloth is large, which increases the amount of raw water by more than...
