Deep harmless treatment septic tank and sewage treatment method

Abstract

The invention relates to a deep harmless treatment septic tank and a sewage treatment method, and belongs to the building technical field. The septic tank comprises a water inlet pipe, an overflow type water passing pipe, a water outlet pipe, a power type water outlet pipe, a shell wall and inner separation plates; the septic tank is divided into a first-level corruption chamber, a second-level corruption sedimentation chamber, a third-level corruption coagulating sedimentation chamber, a fourth-level corruption clarification chamber, a fifth-level deep corruption sterilization chamber, a clear water storage chamber, a scum supplement corruption chamber, a sludge supplement corruption chamber and a power lifting corruption chamber by the inner separation plates. The septic tank has obvious advantages of strong bearing capacity, long service life, acid and alkali corrosion resistance, convenient installation, no leakage, good sewage treatment effect and the like, allows the use of the septic tank space to be maximized, solves the problem that corruption time is no enough because liquid manure does not go into the septic tank and flow out of the septic tank continuously, is full in corruption of liquid manure, and performs deep corruption and sterilization of clarified water fluid; and moreover, with the arranged clear water storage chamber, secondary pollution is avoided.

Description

technical field [0001] The invention belongs to the technical field of construction, and in particular relates to a deep harmless treatment septic tank and a sewage treatment method. Background technique [0002] The septic tank is a device for treating feces and filtering and sedimenting; the principle is that the solidified matter decomposes at the bottom of the pool, and the hydrated objects on the upper layer flow into the pipeline to prevent the pipeline from being blocked, and provide enough water for the solidified objects (feces and other garbage) Time hydrolysis; septic tank refers to a small-scale treatment structure that separates domestic sewage for sedimentation and anaerobically digests sludge. [0003] The earliest septic tanks originated in Europe in the 19th century and have a history of more than 100 years; the original purpose of setting up septic tanks in urban living areas was to collect fertilizers. , Septic tanks have played a positive role in protecti...
