A method of layered water intake in high-algae water sources

Abstract

The invention provides a method for taking water layer by layer in high algae-laden water source places. The method comprises the following steps of firstly judging whether water bloom is generated based on chlorophyll concentration and algae cell density; detecting water quality indexes of water bodies at different depths if water bloom is not generated, and moving a water taking head part to a water layer with a relatively good water quality index; detecting temperatures of different water layers if water bloom is generated, and judging whether temperature layering is generated or not; measuring the depth of a euphotic layer of a water body if the temperature layering is not generated, and moving the water taking head part below the depth of the euphotic layer; moving a water taking opening to a water layer with relatively low chlorophyll concentration and relatively good water quality index based on water quality indexes and chlorophyll concentrations at different water depths if the temperature layering is generated; after adjusting the position of the water taking opening, detecting the chlorophyll content in water dynamically, and repeating the steps above to adjust the position of the water taking opening if the chlorophyll concentrations exceed the standard. The water taking method can be used for reducing the algae content of intake water of a water factory, and reducing the algae removing cost.

Description

technical field [0001] The invention relates to a method for improving the influent water quality of a water plant, in particular to a layered water intake method for reducing the algae content in the influent water of a water plant from the source. Background technique [0002] There are currently more than 5,000 deep-water reservoirs in China, most of which supply water to cities and towns. Due to the economic development in recent years, a large amount of pollutants containing nitrogen, phosphorus and other substances have been discharged into the reservoir, causing a large number of algae growth in the water body. And this water will enter the waterworks through the water intake, and too much algae will also block the filter tank and affect the process operation. In the season when algae blooms are formed, the algae-rich water body in the high-algae water source may release toxic and harmful substances, which will seriously affect the water quality of the water source. ...

Problems solved by technology

The water will enter the waterworks through the water intake, and too much algae will block the filter and affect the operation of the process

In the season when algae blooms are formed, the algae-rich water body in the high-algae water source may release toxic and harmful substances, which will seriously affect the water quality of the water source

As a result, the effluent from the water plant contains toxic substances and also has peculiar smell, which cannot meet the water quality requirements for drinking water
