Rare-earth blue algae treating agent and preparation method thereof

Abstract

The invention discloses a rare-earth blue algae treating agent. The treating agent is characterized by being prepared from the following raw materials in parts by weight: 25-30 parts of polymeric aluminium, 20-24 parts of magnesium chloride, 19-21 parts of aluminium sulfate, 14-18 parts of a rare earth compound, 18-20 parts of nanoparticle activated carbon, 17-19 parts of boric acid, 15-18 parts of ferrous chloride, 1-3 parts of houttuynia cordata, 2-5 parts of chamomile, 3-5 parts of Chinese lovage and 2-5 parts of dahurian angelica root. The prepared blue algae treating agent is safe and efficient, is low in energy consumption and has excellent coagulation performance and big and tight alum floc, and removed sludge has small compact volume and high settling velocity.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a rare earth type cyanobacteria treatment agent and a preparation method thereof. Background technique [0002] In recent years, with the continuous increase of my country's population and the rapid development of industrial and agricultural production, water demand has increased rapidly, and water pollution has become more and more serious. [0003] Water pollution is one of the most serious and harmful pollutions in the world today. The large amount of sewage discharge in my country has led to an increase in pollutants in rivers and lakes such as Taihu Lake. The pollution rate has exceeded the purification capacity of the lake itself. Some of them contain phosphorus. , a large amount of nitrogen-containing compounds, accelerated the eutrophication process of rivers and lakes, led to the abnormal growth of algae, especially cyanobacteria, and formed a layer of bluish-gree...

Problems solved by technology

[0008] The main method adopted at present is to invest a lot of manpower and material resources in the external environment to transfer pollution, such as clearing and flushing, relocating polluting enterprises, etc., and has not solved the pollution from the root cause; in terms of internal environmental governance, despite the emergence of biological methods ( Various methods and treatment agents for treating cyanobacteria, including microbial methods, animal methods, and chemical methods, are still difficult to be widely and effectively applied. higher
