Comprehensive treatment method of landscape water eutrophication and algae overgrowth

Abstract

The invention discloses a comprehensive treatment method of landscape water eutrophication and algae overgrowth. The comprehensive treatment method includes: 1) chemical dephosphorization, namely dephosphorization medicament is added into landscape water body; 2) microorganism purification, namely complex microorganism fungicide composed of primary degradation bacteria and auxiliary degradation bacteria is added into the landscape water body; and 3) aquatic plant auxiliary purification, namely aquatic plants are planted in the landscape water body. The invention has the beneficial effects that three methods of chemical dephosphorization, microorganism purification and aquatic plant restoration are organically integrated, the combination mode of the three methods is adjusted according to the characteristics of high contents of organic matters, nitrogen and phosphorus in eutrophication water body, so as to develop strong points and avoid weakness, and finally poor V type water body is purified to the standard of V type water body; and the landscape water body is effectively purified, and algae growth is controlled, thus solving the problem of water body eutrophication.

Description

technical field

[0001] The invention relates to a comprehensive treatment method for landscape water body eutrophication and algae overgrowth. Background technique

[0002] As far as the commonness of water pollution is concerned, urban sewage treatment technology can be used to purify landscape water bodies. However, because most of them are moderate to light pollution, with obvious occurrence periods and high aesthetic requirements, it is not suitable to directly use urban sewage treatment technology to control and treat them. In recent years, my country has carried out some active research and attempts on the purification and treatment of sewage ponds and rivers. From the perspective of technical principles, there are mainly three categories: physical methods, chemical methods, and biological-ecological methods. The above three categories of purification technologies all have different advantages and disadvantages.
