Description

A kind of aluminum ash/sulfur composite cyanobacteria treatment agent and preparation method thereof

technical field

The invention relates to the technical field of water treatment, in particular to an aluminum ash/sulfur composite cyanobacteria treatment agent and a preparation method thereof.

Background technique

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 blue-green and fishy-smelling floating foam on the water surface, that is, blooms, releasing stench. Water quality deteriorates. Large-scale algal blooms, known as "green tides," can deplete the water of oxygen and kill fish. What's more serious is that some species of cyanobacteria (such as Microcystis) also produce microcystins (MCs for short), and about 50% of green tides contain a large amount of MCs. In addition to direct toxicity to fish, humans and animals, MCs are also an important cause of liver cancer.

Cyanobacteria treatment project is a complex system engineering. 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.

Contents of the invention

The purpose of the present invention is to provide a kind of aluminum ash/sulfur composite cyanobacteria treatment agent and its preparation method, to overcome the deficiencies in the prior art.

The purpose of the present invention is achieved like this:

An aluminum ash/sulfur composite cyanobacteria treatment agent is characterized in that it is made of the following raw materials in parts by weight: aluminum ash 25-29, sulfur powder 12-14, cactus mucus 17-19, acetic acid 16-18, palygorskite 19-21, Calcium Chloride 18-20, Sodium Chloride 16-19, Ma Sang 1-3, Artemisia annua 2-4, Ume 3-6, Pomegranate Peel 5-8.

The preparation method of described a kind of aluminum ash/sulfur composite cyanobacteria treatment agent is characterized in that comprising the following steps:

(1) Boil Masang, Artemisia annua, Ume, and pomegranate peel in water for 2-3 hours and filter, soak the filtrate with palygorskite for 30 minutes, dry, and crush into powder;

(2) Send the filter residue of step (1) into a carbonization furnace, calcinate at 575-665°C for 3-4 hours, take out and spray cactus mucus and acetic acid to mix evenly for 50-70 minutes, dry, and pulverize into powder;

(3) Mix calcium chloride and sodium chloride for 30-40 minutes, add aluminum ash and mix for 45-50 minutes, then add sulfur powder and mix for 50-60 minutes;

(4) Mix the reaction materials in steps (1), (2), and (3) for 120-150 minutes

The invention has the following beneficial effects: the invention uses aluminum ash and sulfur powder to compound, adds acetic acid and cactus mucus to modify, not only can effectively eliminate blue-green algae, but also can eliminate water hyacinth and aquatic plants, and become blue-green algae in fresh water areas such as rivers and lakes. Prevention and control provides a new technology of pollution-free control and control, which has broad application prospects.
