Embodiment Construction

[0011] A preparation method of an environment-friendly sewage treatment agent, the raw materials of which include: clay, fly ash, cornstarch, lime, sodium chloride and activated carbon; the weight percentage of each substance is: clay 20-40; fly ash 20-40 ; Corn starch 10~20; Lime 10~20; Sodium chloride 3~5; Activated carbon 3~5; It is characterized in that: its preparation process is as follows:

[0012] First put clay, lime and fly ash into a pulverizer for crushing; put the crushed material in a closed container, add water and let it stand for 48 hours, and prevent the rested material from drying in the shade for 48 hours, and then put it to the air-dried Heat cornstarch in the material, stir fully, make the material and cornstarch mix evenly, the mixed material becomes viscous, add sodium chloride to the mixture, fully mix; leave to stand for 72 hours and then air-dry until the content of the mixture The water content is less than 1%, add activated carbon to the air-dried ...

Abstract

The invention relates to a preparation method of an environment-friendly sewage treatment agent, in particular to a sewage treatment agent using the mixing effect of clay and fly ash, and belongs to the sewage treatment field. The sewage treatment agent comprises raw materials in percentage by weight as follows: 20%-40% of clay, 20%-40% of fly ash, 10%-20% of corn starch, 10%-20% of lime, 3%-5% of sodium chloride and 3%-5% of activated carbon; the clay and the fly ash are taken as principal raw materials for sewage treatment, so that the sewage treatment cost is reduced; the absorption and flocculation capacity of the clay is high, the sedimentation time is short, and sludge is less, so that the sewage treatment effect and the efficiency are improved further; and the corn starch and the activated carbon are added, so that the absorption and flocculation capacity is improved further, and no chemical agent is left in treated water.

Description

[0001] technical field [0002] The invention relates to a preparation method of an environment-friendly sewage treatment agent, in particular to a sewage treatment agent utilizing the mixed action of clay and fly ash, belonging to the field of sewage treatment. Background technique [0003] With the continuous development of industry, the use of resources is also increasing. Especially water resources, less than 1% of the fresh water or about 0.007% of the water on the earth can be directly used by humans. Thus saving water resources and reusing water resources has become the angle of attention of people. In the reuse of water resources, sewage treatment is the most important. There are many ways to treat sewage at present, but it is generally treated by adding chemical agents, which will leave chemical elements in the water, which will cause certain harm to the human body. Contents of the invention [0004] In order to achieve the above object, the object of t...
