Description

Water purification method and facilities for water without water source

technical field

The invention relates to a water quality purification method for water areas without water sources, in particular to a water quality treatment method and facilities for large-scale water areas without water sources in cities.

Background technique

With the rapid development of economy and urbanization, the problems of water pollution and water shortage are becoming more and more serious. The most serious problems are those large waterless waters, that is, lakes and reservoirs without fixed rivers. Supplement to a fixed water source, the fluidity of the water is poor while evaporation and concentration, coupled with the eutrophication of the water body caused by nitrogen and phosphorus substances in the water, resulting in the excessive reproduction of algae in the water, which is the phenomenon of algal blooms, reducing the transparency of the water, leading to water blooms Dissolved oxygen decreases, making the water smelly; in addition, some algae produce toxins that endanger aquatic organisms, affect human health, and destroy aquatic ecology.

For those waters without water sources in the city, most of them are modern parks integrating leisure, entertainment, cultural and sports activities in the city, which have played a beneficial role in the physical and mental health of the masses, so the purification of their water quality is particularly important. However, the existing treatment methods are relatively simple, and the staged treatment is mainly adopted by dosing drugs. Due to the relatively poor fluidity of the lake water, the treatment effect is not obvious, and at the same time, the added drugs have adverse effects on the water quality.

At present, landscape water bodies such as parks, rivers and lakes in major cities are lacking or exhausted. In order to protect the existing water bodies of rivers and lakes, most of them have used reclaimed reclaimed water as water source, and some have achieved certain economic benefits and social benefits. In addition, due to the lack of water resources, in order to save water resources, many urban green spaces, park constructions and large landmark buildings, artificial lakes, artificial rivers and landscape pools use recycled reclaimed water for water replenishment, irrigation, toilet flushing, etc.

Although reclaimed reclaimed water solves the problem of replenishing water in the landscape, due to various reasons such as small amount of supplemented water, poor fluidity of the water body, evaporation and osmosis concentration of the water quality, the concentration of nutrients in the water increases, etc., the water body deteriorates and the phenomenon of algae bloom occurs, which affects the landscape use of the water body Function. Therefore, in terms of landscape water management, to reasonably solve the problem of replenishing water sources, the purification capacity of water bodies should also be increased. Therefore, it is necessary to propose a relatively complete method and facility for water treatment and maintenance of water bodies without water sources.
