Auto-control water source layering water taking method and system based on three-dimensional algae ecology model

Abstract

The invention provides an auto-control water source layering water taking method and system based on a three-dimensional algae ecology model. The method comprises the steps that 1, water quality, hydrology and meteorology data of a water intake in a water source water body are collected through a data collecting system; 2, the obtained water quality, hydrology and meteorology data are processed through a simulation forecasting system, the pollution load of rainfall runoff entering the water body is calculated in a simulating mode through a watershed hydrologic model, the algae distribution condition in the water source water body is predicted in a simulating mode through a water quality ecology model, and vertical distribution data of algae at the water intake are obtained; 3, the vertical distribution data of the algae at the water intake are analyzed by an automatic control system to determine a lowest algae concentration water layer at the water intake, and a water taking device is controlled to take water at the lowest algae concentration water layer. According to the method, it can be scientifically guaranteed that the algae concentration of the taken water is lowest within the range of the water intake, the phenomenon that water plant production even user health are threatened due to the problem of outbreak growth of the algae is effectively avoided, and the important significance on urban safety water supply is achieved.

Description

technical field [0001] The invention relates to urban safe water supply technology, in particular to a method and system for self-controlled water source layered water intake based on a three-dimensional algae ecological model, which is suitable for water intake from water bodies with algae outbreak risk or history. Background technique [0002] Water is the material basis for human survival. Drinking water safety is related to people's health and life safety. Doing a good job in ensuring the safety of drinking water is the actual manifestation of protecting the most fundamental interests of the people. In recent years, the issue of drinking water safety has been continuously received high attention. [0003] According to the "2013 China Water Resources Bulletin" issued by the Ministry of Water Resources, in 2013, 262 large reservoirs, 381 medium-sized reservoirs and 24 small reservoirs nationwide, a total of 667 major reservoirs were evaluated for water quality. There are ...

Problems solved by technology

[0008] Reservoir layered water intake technology has been applied in reservoirs as early as the 1990s, but so far there are few layered water intake devices for water quality problems, most of which are mainly concentrated in the field of low temperature water problems in large reservoirs, and a few are related to water quality also only related to iron, manganese or dissolved oxygen, and there was no research related to algae concentration
