Water quality safeguard system and water quality safeguard method for drinking water reservoir

Abstract

The invention provides a water quality safeguard system and a water quality safeguard method for a drinking water reservoir. According to the water quality safeguard system and the water quality safeguard method, an automatic water quality monitoring mechanism, a water inflow regulating and controlling mechanism, a reservoir area water ecology mechanism and a water outflow regulating and controlling mechanism are adopted to treat raw water which flows from a river channel into the reservoir. The water quality safeguard system and the water quality safeguard method, provided by the invention, have a wide application range, play a favorable role in water qualification and water quality safeguard of drinking water reservoirs in plain and mountain areas, have the advantages of high water quality safeguard property, good water qualification effect and high water supply safety, reflect the concepts of ecological preservation, low carbon, environmental protection and the like, have high economy, high practicability and wide applicability, are especially suitable to popularize and apply among drinking water reservoirs with unstable raw water quality, long water retention time, eutrophication risks, low water supply assurance rates and emergency water storage functions.

Description

technical field [0001] The invention belongs to the technical field of water conservancy engineering and environmental engineering, and relates to a water quality guarantee system and a guarantee method for a drinking water reservoir, and in particular to a water quality guarantee system and water quality maintenance, eutrophication prevention and control of a drinking water reservoir with a long exchange period. Ways to ensure water quality safety. Background technique [0002] As an important source of drinking water for the urban population, drinking water supply reservoirs need to ensure the safety of their water quality. At present, many drinking water supply tanks in my country have one or more problems such as green water color, water body odor, fish death, unstable water quality, algae accumulation, and high eutrophication. There are many reasons for water quality changes in water supply reservoirs, among which the most important and most critical reason is: reservo...

AI Technical Summary

Problems solved by technology

There are many reasons for water quality changes in water supply reservoirs, among which the most important and most critical reason is: reservoirs in mountainous areas are restricted by the inflow of water from upstream and uneven distribution of rainfall time, reservoirs in plain areas are affected by unstable water quality of river networks, in order to be able to To store enough high-quality raw water to meet the requirements of drinking water supply throughout the year, reservoirs with large storage capacity are often built according to the topography, which leads to low exchange rate of reservoir water, long residence time, poor water fluidity, and external surface Due to the discharge of source pollution and the impact of atmospheric dustfall, the water quality of the reservoir gradually deteriorates, which in turn affects the guarantee rate of water supply

[0003] At present, in order to solve the problem of water quality deterioration in water supply reservoirs with long water exchange cycles, some reservoirs have adopted fish such as silver carp and bighead carp to reduce the accumulation of algae; plant emergent plants around the reservoir to increase the purification effect on the water body ; Routine monitoring of water supply quality; measures such as supplementary oxygenation in local reservoir bays

These measures can play a certain role in the local reservoir area, but there are still great deficiencies in improving the water quality of the whole reservoir, maintaining the water quality of high-quality water bodies and ensuring the safety of water supply, and the effect is not ideal

[0004] It can be seen that the existing water quality assurance technology for drinking water supply reservoirs has great limitations and needs further research and exploration
