Superposed group water inlet lifting pump room

Abstract

The invention discloses a superposed group water inlet lifting pump room. The superposed group water inlet lifting pump room comprises a water inlet valve room, a water collecting pond, a lifting pumproom, a wastewater recovery pond, a sodium hypochlorite pre-adding room and dosing room, and an electricity transformation and distribution room; the water collecting pond, the wastewater recovery pond and the sodium hypochlorite pre-adding room and dosing room are in a three-layer superposed arrangement from top to bottom in sequence; the water collecting pond is positioned at the bottommost layer; the wastewater recovery pond is positioned at an intermediate layer; the sodium hypochlorite pre-adding room and dosing room is positioned at the topmost layer; a water inlet valve room and the lifting pump room are respectively arranged at the front end and the rear end of the three-layer superposed structure in sequence; the water collecting pond is partitioned into a front rectifying pond and a rear rectifying pond by arranging a perforated tracery wall in the front section of the water collecting pond; a wastewater recovery pond water inlet pipe is arranged at the tail end of the wastewater recovery pond, and an overflow weir is arranged on the partition wall close to the front end; the sodium hypochlorite pre-adding room and dosing room is arranged above the wastewater recovery pond; the lower part of the water inlet valve room communicates with the water collecting pond; and a horizontal overflow culvert is arranged in the centre of the water inlet valve room. According to the superposed group water inlet lifting pump room, the problem that the land utilization rate of a building which is arranged in areas according to conventional functions can be solved.

Description

technical field [0001] The invention relates to the technical field of engineering construction of a municipal water supply treatment plant, in particular to a superimposed group water inlet lifting pump room. Background technique [0002] In the layout of the water plant, the conventional method is to classify the waterline, mudline, and subsidiary treatment units according to the functional division, and arrange the division plane independently. The land utilization rate is not high, and there is a lack of horizontal comparison and analysis of the design water level process of different types of treatment units. . [0003] Especially when the land occupation of the water plant is limited and the effluent water quality standard is high, when the inflow lift pump room is arranged independently, it is usually realized by reducing the adjustment and storage volume of the sump tank and increasing the start-stop frequency of the lift pump, and the water supply safety is relative...

AI Technical Summary

Problems solved by technology

[0008] In order to overcome the defects and deficiencies of the above-mentioned technologies, the present invention provides a superimposed group water inlet lifting pump room, which solves the problem that the land utilization rate of the structures arranged according to the traditional functional divisions is not high when the water inlet pipes are buried deep; Improve the production and operation safety and high energy consumption caused by the increase of water treatment structures and the sacrifice of the storage volume of the collection tank; solve the problems of high roof load, waste of space, and high project cost when the influent water level is low; Solve the problem of low inlet water level and waste of head space when the backwash water gravity of the filter enters the design of the filter; solve the tight comprehensive layout of the factory plane pipeline caused by the separate setting of the chemical storage and dosing points when the factory area is tight, The problem of increased investment
