Embodiment Construction

[0013] Described a kind of inorganic / organic flocculant compound powdery cyanobacteria treatment agent is characterized in that, is made of the raw material of following weight part: polysilicate ferric sulfate 28, chitosan 17, kaolin 18, ammonium sulfate 14, high iron Potassium Acid 15, Sodium Carboxymethyl Cellulose 16, Perrin 2, Saffron 1, Nepeta 5, Clove 3, Senecio 4.

[0014] The preparation method comprises the following steps:

[0015] (1) Boil Peilan, saffron, Nepeta, clove, and Senecio in water for 2-3 hours and filter, soak the filtrate with kaolin for 30 minutes, dry, and crush into powder;

[0016] (2) Send the filter residue from step (1) into a carbonization furnace, calcinate at 550-650°C for 3-4 hours, take it out, and crush it into powder;

[0017] (3) Mix chitosan and ammonium sulfate for 30-40 minutes, add potassium ferrate and mix for 45-50 minutes, then add carboxymethylcellulose sodium and mix for 50-60 minutes;

[0018] (4) Mix the reaction materials o...

Abstract

The invention discloses a combined inorganic / organic flocculant powdery cyanobacteria treating agent. The powdery cyanobacteria treating agent is characterized by comprising the following raw materials in parts by weight: 27-30 parts of polymeric ferric silicate sulfate, 17-19 parts of chitosan, 18-20 parts of kaolin, 14-17 parts of ammonium sulfate, 15-18 parts of potassium ferrate, 14-16 parts of sodium carboxymethyl cellulose, 2-4 parts of Eupatorium fortunei, 1-3 parts of saffron crocus, 2-5 parts of wormseed goosefoot, 3-5 parts of cloves and 4-7 parts of groundsel. The cyanobacteria treating agent disclosed by the invention can remove various pollutants and harmful substances in broad-spectrum and efficient manner and has a strong adaptability to high polluted concentration, wide PH range and wide temperature changes of sewage and has the advantages of high turbidity and phosphorus removal efficiency, fast flocculation speed, less pharmaceutical dosage and less sludge amount and the like.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to an inorganic / organic flocculant composite powdery 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...
