Urban and rural safe water supply integrated control method

Abstract

The invention discloses an integrated control method for urban and rural safe water supply. The method comprises the following specific steps: 1) partitioning a rural water distribution pipe network; the maximum free water pressure of the pipe network in each water supply subarea of the village and town water supply pipe network is not more than 50m, and the minimum free water pressure needs to meet the requirement of concentrated water supply to each water plant and station in village and town; the pressure difference between the high area and the low area of each pipe network subarea is 20-45 2) urban and rural water supply integrated water supply system control; all water plants and stations are transformed into a peak regulation pump station water supply mode, water distribution main lines from a central city water plant to all village and town peak regulation pump stations are adjusted into water delivery main lines, and joint debugging and joint control are achieved for operation of the central city water plant and the peak regulation pump stations. A peak regulation mode of water plant direct supply or series pressurization and pool or water storage tank pressurization is adopted; at ordinary times, water plant direct supply or series pressurization is performed, pool pressurization intervenes in peak clipping during peak operation, and peak clipping time is three time periods of morning, noon and evening. According to the invention, the technical problem of integration of urban and rural water supply can be solved on the premise of low investment of the water distribution pipe network part and low operation cost.

Description

technical field [0001] The invention relates to a control method for urban and rural integrated water supply. Background technique [0002] The status quo of drinking water in the vast rural areas of our country and the water supply mode are generally divided into two ways: one is the direct supply of water source wells, and the other is the water supply mode of small water supply plants and stations. The first way is to use the well water to directly use the water supply. That is, one or more water source wells are drilled in villages and towns, and after disinfection, they are directly connected to the pipe network for village and town water supply. The second is the water supply method of small water supply plants and stations. The water source comes from one or more water source wells, and the groundwater is taken and transported to small water supply plants and stations in villages and towns. The pressure pump group and the water supply pipe network supply water to di...

Problems solved by technology

In addition, at present, the underground water source wells of various water supply plants and stations are mostly located in the water supply plants, station factories or surrounding farmlands, without effective protection. There are often operations such as fertilization and pesticide spraying near the water source wells. Into the seepage water source well, causing groundwater sources to be polluted to varying degrees

[0005] The traditional rural water supply method has led to the complete isolation of the water supply systems in various villages and towns, with long distances and no interconnection, which makes it impossible to achieve unified control, management and scheduling

The management method is simple, and the water volume, water pressure, and water quality cannot be accurately controlled, which makes the rural water supply seriously lacking in safety and wastes a lot of resources and energy
