Intermediate storage tank and sewage source separation system based on negative pressure

Abstract

The invention relates to an intermediate storage tank for collecting domestic sewage and also relates to a domestic sewage source separation system under negative pressure adopting the intermediate storage tank. The intermediate storage tank comprises a tank body, an induction valve, a control valve, a storage tank sewage discharge negative pressure valve and a microprocessor, wherein, the tank body is provided with an induction tube and a storage tank sewage discharge pipe, the upper middle part of the tank body is provided with a sewage inlet and the upper part of the tank body is provided with one or a plurality of air inlets, the lower end ports of the induction tube and the storage tank sewage discharge pipe are positioned inside the tank body, the upper part of the inner cavity of the induction tube is communicated with the induction valve by an internal pressure connecting mouth, an induction signal output route of the induction valve is connected with a signal input terminal of the microprocessor, a control signal output line of the microprocessor is connected with a control route of the control valve, a negative pressure control pipeline of the control valve is connected with a negative pressure control cavity of the storage tank sewage discharge negative pressure valve, and the storage tank sewage discharge pipe is connected with a negative pressure sewage discharge pipeline by the storage tank sewage discharge valve. The domestic sewage source separation system comprises a plurality of the intermediate storage tanks and one or a plurality of sewage collection tanks, and is provided with a uniform negative pressure source. The domestic sewage source separation system is beneficial to reducing power consumption and realizing the source separation of the domestic sewage.

Description

technical field [0001] The invention relates to an intermediate storage tank for domestic sewage water collection, and also relates to a domestic sewage source separation system based on negative pressure using the intermediate storage tank. technical background [0002] The existing domestic sewage system mainly adopts the gravity flow method for sewage collection. Various domestic sewage is collected together through the gravity flow pipeline, and discharged into the septic tank near the residence. After simple biological digestion, the overflow or Use the sewage pump to discharge the sewage in the septic tank into the municipal sewage pipeline, send it to the municipal sewage treatment plant together with other municipal sewage for centralized treatment, and directly discharge it into the river in places where there is no treatment condition. The defect of this technology is mainly due to the mixing of sewage with different pollution levels, which greatly increases the am...
