Problems solved by technology

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

Embodiment Construction

[0013] The mixed-type cyanobacteria treatment agent is characterized in that it is made of the following raw materials in parts by weight: polyaluminum chloride 26, trichloroethylcyanuric acid 18, eugenol 14, diatomite 24, calcium silicate 20 .

[0014] The preparation method comprises the following steps:

[0015] (1) Boil babu, knotweed, licorice, and burdock in water for 2-3 hours and filter, take the filtrate and diatomaceous earth and soak it for 30 minutes, dry it, and crush it into powder;

[0016] (2) Send the filter residue of step (1) into a carbonization furnace, calcinate at 570-655°C for 3-4 hours, take out and spray eugenol until mixed evenly for 45-60 minutes, dry and pulverize into powder;

[0017] (3) Mix trichloroacetylcyanuric acid and calcium silicate for 30-40 minutes, add potassium dihydrogen phosphate and mix for 45-50 minutes, then add diammonium edetate and mix for 50-60 minutes;

[0018] (4) Mix the reaction materials of steps (1), (2), (3) and othe...

Abstract

The invention discloses a mixed blue-green algae treating agent which is characterized by being prepared from the following raw materials in parts by weight: 25-29 parts of aluminum polychlorid, 18-20 parts of trichloroisocyanuric acid, 14-17 parts of eugenol, 18-24 parts of diatomite, 18-20 parts of calcium silicate, 17-19 parts of monopotassium phosphate, 18-21 parts of diammonium ethylenediaminetetraacetate monohydrate, 1-3 parts of sessile stemona root, 2-4 parts of giant knotweed, 3-5 parts of liquoric root and 3-6 parts of great burdock achene. The blue-green algae treating agent is good in algae-removing effect, wide in pH application range, wide in sewage temperature change, higher in alkalinity than other aluminum salts and iron salts, low in erosion and corrosion to equipment, convenient and safe to use and free from secondary pollution to the environment, and has a deodorizing effect.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a mixed 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. 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-green and fishy-smellin...
