A sewage purification treatment device for a municipal sewage pipe network

Abstract

The invention relates to the technical field of sewage treatment, and aims to provide a sewage purification treatment device for a municipal sewage pipe network, including a crushing tank, a settling tank, a biodegradation tank and a sludge tank; There is an outlet pipe connected to the settling tank, and the crushing tank is provided with a heavy crushing disc and a light crushing disc in sequence from top to bottom; the heavy crushing disc is provided with a number of paddles, and the sewage enters the crushing tank and impacts on the paddles to give Heavy shredding disc drive. The sewage entering the crushing tank is crushed successively by using the heavy crushing disc and the light crushing disc, and the driving force generated by the impact of the sewage on the paddle and the energy stored by the heavy crushing disc driven by the geared motor are used after the geared motor stops driving. It can still overcome a large amount of resistance generated during rotation, so that the heavy crushing disc and the light crushing disc can keep or continue to rotate for a long time, thereby reducing the burden on the geared motor, allowing the geared motor to get sufficient cooling time and prolonging the service life.

Description

technical field [0001] The invention relates to the technical field of sewage treatment and aims to provide 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. [0003] At present, the Chinese patent document with the application publication number of CN106746187A in the prior art discloses a sewage purification treatment device for a municipal sewage pipe network, including a settling tank and a crushing tank. One s...

Problems solved by technology

[0004] However, there is a steady stream of domestic sewage, and the crushing tank needs to be crushed for a long time without interruption. The first motor and the second motor must be kept in operation for a long time, which not only consumes high energy, but also reduces the life of the motor due to excessive heat generation.
