Biological purification tank for household domestic sewage treatment

Abstract

The invention belongs to the technical field of purification tanks, and particularly discloses a biological purification tank for household domestic sewage treatment. The biological purification tank comprises a tank body and a cover body, wherein the cover body is detachably fixed to the top end of the tank body; an anaerobic chamber, an aeration chamber, a settling chamber and a disinfection chamber are sequentially arranged in the tank body from left to right; a first isolation chamber is arranged at the inner top end of the anaerobic chamber, and an intermittent material guide assembly is arranged in the first isolation chamber; the top end of one side surface of the tank body is in threaded connection with a water inlet pipe; one end of the water inlet pipe penetrates through the anaerobic chamber and extends into the first isolation chamber; a sewage discharging chamber is arranged at the bottom of the tank body; a sewage discharging outlet is formed in one end of the sewage discharging chamber; a second isolation chamber is arranged on one inner side of the sewage discharging chamber; and a continuous sewage discharging assembly is arranged in the second isolation chamber. Through the arrangement of the intermittent material guide assembly and the continuous sewage discharging assembly, the technical effects of orderly purifying sewage to avoid reverse flow and quickly and effectively discharging sewage to avoid blockage are achieved.

Description

technical field [0001] The invention relates to the technical field of purification tanks, in particular to biological purification tanks for household sewage treatment. Background technique [0002] At present, most of the sewage flowing out from toilets, kitchens, and washing rooms is directly discharged into septic tanks for storage without purification. Septic tanks only store these domestic sewage, and after a period of time, these unpurified domestic sewage are directly discharged into rivers, ponds, lakes, and oceans, which is the direct cause of environmental pollution. In order to protect the environment, people set up biological purification tanks in their residences. [0003] The purification tank is a small sewage treatment device, which is used for the treatment of dispersed domestic sewage or similar domestic sewage. After the sewage enters the purification tank, it is pretreated first, and the particles and suspended solids with relatively large specific grav...

Problems solved by technology

[0005] The embodiment of the present application provides a biological purification tank for household sewage treatment, which solves the technical problems in the prior art that too much sewage is transported to the purification tank at one time, resulting in too little time for purification and the inability to quickly and effectively discharge filtered dirt. The technical effect of orderly purifying sewage to avoid counterflow and quickly and effectively discharging sewage to avoid clogging
