Method for improving water quality of drinking water source

Abstract

The invention relates to a method for improving water quality of a drinking water source. The method comprises the following steps: (1) removing bottom sludge of a target water; (2) determining a total water volume of the target water as well as a nitrogen content, a phosphorus content and a content of chlorophyll a in the water; (3) dispensing daces, chubs, bighead carps, crucians and weevers into the target water in a ratio of (45 to 55): (25 to 31): (15 to 20): (2 to 5): (1 to 2) according to the total water volume, the nitrogen content, the phosphorus content and the content of the chlorophyll a; (4) and fishing after the daces are dispensed for 8 to 12 months. The water quality of the drinking water source is improved by removing the bottom sludge in combination with the increment of aquatic animal fishes in the water, the algae in the water is reduced, the harm of tap water on the human body can be alleviated, and the disease occurrence probability caused by the water can be reduced; and the advantage of the bottom sludge removal of the water is to remove the phosphorus and heavy metals deposited in the bottom sludge; and on the other aspect, the content of the phosphorus of the water can be controlled.

Description

technical field [0001] The invention relates to the technical field of water body ecological restoration methods, in particular to a method for improving the water quality of drinking water sources. Background technique [0002] Water is the source of life, the foundation of life, and the key to development. Water development and water management are related to the country's prosperity and people's security, and are an important support for industrialization, urbanization, and agricultural modernization. At present, 80% of the water environment in our country is already in a polluted state. Water environment pollution has exacerbated the crisis of drinking water sources. Due to water pollution, many diseases have occurred. According to the statistics of the World Health Organization, more than 70% of human diseases are related to Water is poor, so improving the water quality of drinking water sources has become an urgent need at present. [0003] Although various measures h...

Problems solved by technology

[0003] Although various measures have been adopted and a lot of money has been invested in the treatment of drinking water sources, the water quality has not been improved, or the improvement effect is not obvious. The main reason is that the endogenous pollution of drinking water sources has not been eliminated. However, the main source of endogenous pollution in drinking water sources is water eutrophication

There are many ways to control the eutrophication of water bodies. There are four specific methods: physical, chemical, microbial, and biological. However, none of these methods can fundamentally solve the problem of eutrophication in water bodies.
