A method for treating landscape water with a treatment agent

Abstract

The invention provides a compound treatment agent for a landscape water body. The compound treatment agent comprises polyferric sulfate and purple parent rock. The compound treatment agent provided by the invention has the advantages of low cost, wide source and environmental friendliness, can be used for treating landscape water bodies different in pollution degree and realizes high purifying efficiency and good treatment effect, wherein the removal efficiency of nitrogen and phosphorus is high, and the removal rate of total nitrogen in the seriously-polluted landscape water body can reach 57.94% while the removal rate of total phosphorus can reach 83.63%; and the damaged ecological balance can be effectively restored so that the ecological system resumes virtuous cycle.

Description

technical field

[0001] The invention relates to a composite flocculant for landscape water body and its application method. Background technique

[0002] In recent years, the construction of urban landscape water bodies has become more and more popular, but the self-purification function, circulation capacity and biological dynamic balance of landscape water bodies are weak, coupled with the unreasonable discharge of domestic sewage, resulting in eutrophication of many landscape water bodies, seriously affecting Surrounding residential and urban environments. Numerous studies have shown that the root cause of eutrophication in urban landscape water is the excessive content of nitrogen and phosphorus nutrients. Therefore, reducing nitrogen and phosphorus in water is the focus of landscape water eutrophication control, especially phosphorus, which is a controlling factor of water eutrophication. Currently, the most effective method for removing phosphorus from landscape wate...
