Construction process of municipal sewage purification system

Abstract

The invention relates to aconstruction process of a municipal sewage purification system. The process comprises the following steps: building a sewage treatment system, hinging a filter plate in a treatment tank of the sewage treatment system; connecting a first filter screen and a second filter screen to two ends of the filter plate respectively, wherein the first filter screen is connected to the side wall of the treatment tank through a connecting piece, and the second filter screen is connected with an opening of a collecting container, so that in the moving process of the filter plate, the first filter screen, the filter plate, the second filter screen and the collecting container form a filter layer with a continuously changing form, and the filter layer divides the treatment tank into an upper area and a lower area; and in the process that sewage is continuously discharged into the treatment tank and the form of the filter layer is continuously changed, the filter layer is always located between the water inlet pipe and the water discharge pipe, so that the probability that impurities are discharged from the water discharge pipe is reduced while the purification efficiency of the system is improved.

Description

technical field [0001] The present application relates to the technical field of construction engineering, in particular to a construction process of a municipal sewage purification system. Background technique [0002] The municipal sewage purification system is a facility for discharging sewage after filtration and disinfection. In related technologies, the municipal sewage purification system includes a holding tank. The mouth of the nozzle is located above the filter screen, and the nozzle of the drain pipe is located below the filter screen. The sewage is discharged from the water inlet pipe, and after being filtered by the filter screen, it is discharged from the drain pipe, thereby completing the preliminary purification of sewage. [0003] In view of the related technologies mentioned above, the inventor believes that: the accumulated sundries on the surface of the filter net will affect the filtration efficiency of sewage. When the sundries need to be cleaned, the h...

Problems solved by technology

[0003] In view of the related technologies mentioned above, the inventor believes that: the accumulated sundries on the surface of the filter net will affect the filtration efficiency of sewage. When the sundries need to be cleaned, the holding tank needs to stop entering the sewage before the sundries can be cleaned. Affects the efficiency of the purification system for the initial purification of sewage, so there is still room for improvement
