Sewage purification treatment device of municipal sewage pipeline net

Abstract

The invention discloses a sewage purification treatment device of a municipal sewage pipeline net. The sewage purification treatment device comprises a settling basin and a crushing tank, wherein blow down branches are arranged at the top of the crushing tank; a first motor and a second motor are arranged on the left side wall of the crushing tank; rotating rods which penetrate through the crushing tank are arranged on the right sides of the first motor and the second motor; the rotating rods are both provided with crushing hammers; a sludge collecting tank is arranged at the bottom of the outlet of a sludge collecting tube; an air inlet tube is connected with the left side of an aerator; an air outlet tube is arranged at the top of a biodegradation tank; a first feeding hole is formed in the right side of the air outlet tube; the bottom of the biodegradation tank is connected with a sludge tube; a sewage pump is arranged on the right side of a sewage backflow tank; the sewage pump is communicated with the biodegradation tank; a sterilization tank is connected with the right side of the biodegradation tank through a connecting pipeline; a second feeding hole is formed in the top of the sterilization tank; a clean water tube is arranged at the bottom of the sterilization tank. The sewage purification treatment device is simple in structure, high in working efficiency, short in construction period and low in sewage treatment cost.

Description

technical field [0001] The invention relates to the technical field of sewage purification treatment, in particular to a sewage purification treatment device for a municipal sewage pipe network. Background technique [0002] The problem of sewage treatment has been paid more and more attention by the society. With the process of urbanization and the development of industrial society, on the one hand, water consumption continues to increase, and water resources are increasingly scarce; on the other hand, sewage discharge is increasing, and environmental pollution is becoming more and more serious. Therefore, the urban sewage treatment system is the key to solve the shortage of water resources and serious environmental pollution. Urban sewage mainly comes from domestic sewage discharged from households, institutions, businesses, urban public facilities, etc., and a moderate amount of industrial production wastewater. The amount of wastewater is large and there are obvious diu...
