A domestic sewage purification treatment device

Abstract

The invention relates to the technical field of sewage treatment, in particular to a domestic sewage purification device. The domestic sewage purification device comprises a water inlet pipe, a treatment tank and a water outlet pipe and is characterized in that a flow guide part is arranged in the water inlet pipe, the water inlet pipe is branched at the flow guide part into a continuous water pipe and a washing water pipe, and the tail end of the continuous water pipe is communicated with the lateral wall of the bottom of the treatment tank; a limit channel is arranged between the treatment tank and the water outlet pipe, the diameter of the limit channel gradually decreases from the treatment tank to the water outlet pipe, a limit block with a cavity is arranged at the top of the treatment tank, and a limit block and the inner wall of the treatment tank form the limit channel; a rotary plate is hinged to the limit block, and the tail end of the washing pipe is opposite to the limit block. The domestic sewage purification device has the advantages that by the flow guide part, domestic sewage can flow along the continuous water pipe, large impact caused by the water flow on the treatment chamber is avoided, waste residues in the treatment chamber cannot be stirred, the domestic sewage can be allowed to wash along the washing water pipe to wash the waste residues in the limit channel back into the treatment chamber, and waste residue filtering is facilitated.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a domestic sewage purification treatment device. Background technique [0002] At present, in modern households, there is a lot of water for domestic use, which leads to an increase in domestic sewage, but few people realize that it is necessary to remove solid particles and kitchen waste in sewage before discharging them into the sewer pipes. Most people directly Drain sewage into the sewer pipe, which is easy to cause pollution to the environment, and most of the garbage in domestic sewage comes from kitchens and bathrooms, such as vegetable residues, bone residues, and some debris and hair strands, which cannot be treated Directly into the sewer pipe, it is easy to block the sewer pipe, and people also need to let professional plumbers dredge the sewer pipe, which increases unnecessary expenses. Contents of the invention [0003] The main purpose of the present inv...
