Abstract

The invention discloses a drying treatment assembly for market-town domestic sewage and sludge. A grille pool comprises a buffer pool and a grille pool body, a manual gate valve is arranged between the buffer pool and the grille pool body, longitudinal grilles are arranged at the lower part of the grille pool body, and an overhaul steel ladder is arranged in the grille body laterally above the grilles; the grille pool body is communicated with a regulating pool, the regulating pool comprises a primary sedimentation pool and a water uniformization pool which are horizontally arranged side by side, the primary sedimentation pool is located on the right side of the grille pool, a sludge pump is arranged at the bottom of the primary sedimentation pool, a water flow channel is arranged on the front side of a partition wall between the primary sedimentation pool and the water uniformization pool, and a water suction pump is arranged at the bottom of the water uniformization pool; an aeration device is arranged at the bottom of the water uniformization pool, opening and closing of the water suction pump and an air blower and an aeration control valve of the aeration device are controlled through a water level indicator, a recycle water pool is connected with a backflushing water inlet pipe of a sand filter, a backflushing water outlet pipe of the sand filter is connected to a backflushing sedimentation pool, and sludge in the backflushing sedimentation pool and sludge in the regulating pool enter a sludge drying pool.

Description

technical field [0001] The invention relates to a sewage and sludge treatment system, in particular to a treatment component for drying domestic sewage and sludge in a town. Background technique [0002] With the enhancement of people's awareness of environmental protection, sewage treatment has become a key issue of concern to governments of various countries. There are three main sources of sewage in my country, namely, decentralized domestic sewage in township residential areas, centralized domestic sewage in urban living areas, and industrial production processes. sewage. Using sand to purify sewage is a traditional sewage treatment method. The existing sewage treatment method has some shortcomings. The removal capacity of TN and TP is low, and some biochemical treatment ponds such as denitrification ponds need to be placed. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides another component for drying dom...
