Problems solved by technology

[0003] Fly ash is a pozzolanic-like moderating material formed after coal powder is burned at high temperature. It is rich in alumina, and there are a large number of active points such as aluminum and silicon in it, which can be combined with adsorbate through chemical bonds. At the same time, the structure of fly ash is very strong. Con

Abstract

The invention discloses a garbage penetrating fluid efficient wastewater treating agent based on modified fly ash and a preparation method. The composition is prepared from, by weight, 50-60 parts of fly ash fine powder, 8-10 parts of dicarbonate, 11-17 parts of poly dimethyl diallyl ammonium chloride, 9-10 parts of cation polyacrylamide, 10-20 parts of carboxymethyl chitosan, 10-20 parts of quaternary ammonium salt of chitosan, 20-24 parts of smectite powder, 6-10 parts of biological bacterial sludges, 12-15 parts of magnetic tourmaline powder, 8-10 parts of basic aluminum chloride, 40-50 parts of loofahs and an adequate amount of ethyl alcohol, deionized water and water. According to the garbage penetrating fluid efficient wastewater treating agent based on the modified fly ash and the preparation method, pretreatment is conducted on coal ash powder through the dicarbonate, the porosity and the specific surface area of the coal ash power are increased, further compound modification is conducted on activation compound powder, the adsorption efficiency is increased, and the garbage penetrating fluid efficient wastewater treating agent based on the modified fly ash and the preparation method have the advantages that the adsorbent of the coal ash powder is high in capacity and easy to separate and recycle.

Description

technical field [0001] The invention belongs to the field of wastewater treatment, and in particular relates to a modified fly ash-based high-efficiency wastewater treatment agent for garbage permeate and a preparation method. Background technique [0002] With the rapid development of cities in our country, the output of garbage continues to increase. During the process of landfilling and stacking, due to the decomposition of organic matter inside the garbage or the combination of free water in the garbage, the garbage seepage is formed. The garbage seepage is a kind of high-concentration organic Wastewater, water quality and quantity are unstable, and the water contains a large amount of refractory substances, so the treatment of garbage permeate filtrate is very difficult. [0003] Fly ash is a pozzolanic-like moderating material formed after coal powder is burned at high temperature. It is rich in alumina, and there are a large number of active points such as aluminum an...
