Sewage purification treatment device for municipal sewage pipe network

Abstract

The invention discloses a sewage purification treatment device for a municipal sewage pipe network, the sewage purification treatment device comprises a pretreatment box, the top end of the pretreatment box is fixedly provided with a mounting box, one end of the mounting box is provided with a liquid inlet pipe, the top end of the interior of the pretreatment box is fixedly provided with a collection cylinder, and the interior of the pretreatment box is fixedly provided with a filter sieve plate. A liquid outlet is formed in one side of the bottom end of the pretreatment box, and an automatic cleaning mechanism is arranged in the pretreatment box. According to the sewage purification treatment device, impurities accumulated on the filtering sieve plate can be cleaned through the cleaning rod and the cleaning brush, hair collected on the hair collecting rod can be cleaned through the air heater, the collected hair and the filtered impurities can be cleaned without disassembling the municipal sewage treatment equipment, the automation degree is high, and the municipal sewage treatment efficiency can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage purification treatment device for a municipal sewage pipe network.

AI Technical Summary

Problems solved by technology

[0003] The existing municipal sewage pipe network generally flows the sewage of the sewage pipe network to one place for centralized treatment. The filter screen of the sewage purification treatment device of the common municipal sewage pipe network is easy to block, and the sewage is generally simply filtered during the treatment process. , but the impurities will remain on the top of the filter screen. When the impurities accumulate more, the filter screen will be clogged, which will reduce the sewage purification efficiency and bring great inconvenience to the sewage purification treatment work, and the content of the municipal sewage source bath water is relatively high Too much hair, the hair is more likely to block the filter, and the hair is inconvenient to clean, time-consuming and labor-intensive
