Sewage treatment device for municipal pipe network

Abstract

The invention discloses a sewage treatment device for a municipal pipeline network, which comprises a sedimentation tank, a sludge mixing tank, a purification tank and an air-dissolving tank. The sedimentation tank is connected to the sludge mixing tank through a mud delivery pipe, and a second Stirring chamber and pressurized pipe, the second stirring chamber is provided with a stirring mechanism, the pressurized pipe is provided with a conveying screw, the end of the conveying screw is provided with a third motor, and a filter ball is provided in the sedimentation tank, which is connected by a sewage pump Purification tank, the purification tank is divided into a first mixing chamber and a purification chamber through a partition, a permeable membrane is set on the partition, the first stirring chamber is connected to the sludge mixing tank through a mud guide pipe, and the upper and lower intervals in the purification chamber are provided with drug discharge pipes and The deflector and the purification pool are connected to the dissolved air tank through the dissolved air water pump. The invention has simple structure and strong practicability, can not only improve the sewage purification treatment effect, make sludge and sewage be separated rapidly, but also facilitate the recycling of sludge and sewage, reduce waste of resources and realize recycling.

Description

technical field [0001] The invention relates to a sewage treatment device for a municipal pipe network. Background technique [0002] With the continuous improvement of people's living standards, domestic sewage discharge is becoming more and more serious. The municipal pipe network also needs to manage the sewage treatment while managing the rainwater treatment, which not only increases the working pressure of the municipal pipe network, but once the pipe network is overloaded, it is easy to cause the deterioration of water resources in some areas. [0003] Sewage treatment device is an indispensable equipment in the municipal pipe network, and its sewage treatment effect directly affects the working stability of the municipal pipe network. The sewage treatment device in the prior art can only be used for the treatment of a small part of sewage, and is not suitable for Large-scale sewage treatment, and high manufacturing and maintenance costs. Contents of the invention ...
