Method for preparing filter material cleaning agent for agricultural planting sewage treatment

Abstract

The invention discloses a method for preparing a filter material cleaning agent for agricultural planting sewage treatment, and relates to the field of cleaning agents. The method comprises the following steps that (1) cotton straw powder, soybean starch and vinyl triethoxysilane are mixed to be uniform, and sintering is carried out in a nitrogen protection atmosphere furnace; (2) a modified aluminum oxide molecular sieve, activated carbon, polytetrafluoroethylene and magnesium silicate are added into the mixture, and the materials are mixed to be uniform and subjected to ball milling; (3) theprepared mixture is pressed into thin blocks through a press, sizing is carried out in a high-temperature high-pressure environment, and then a copper sulfate solution is sprayed; (4) natrii laurylissulfas, fatty alcohol-polyoxyethylene ether and sodium bicarbonate are add into the prepared mixture, and mixing, sintering, cooling and grinding are carried out; (5) the prepared mixture is dissolved in deionized water, hydrochloric acid is dropwise added until the PH value ranges from 5 to 6. The prepared cleaning agent can remove harmful matter adsorbed by a filter material, the filter material is repeatedly recycled, resources are saved, and the sewage purification cost is reduced.

Description

Technical field: [0001] The invention relates to the field of cleaning agents, in particular to a preparation method of a filter material cleaning agent for agricultural planting sewage treatment. Background technique: [0002] Planting is one of the main components of agriculture. It uses land as an important means of production and uses green plants to synthesize organic substances from carbon dioxide, water and minerals in nature through photosynthesis. At the same time, it converts solar energy into chemical energy and stores it in organic matter. in the substance. Including the cultivation of various crops, trees, fruit trees, medicinal and ornamental plants. There are food crops, commercial crops, vegetable crops, green manure crops, fodder crops, pastures, flowers and other horticultural crops. [0003] The sewage in the planting industry mainly includes domestic sewage, precipitation, and planting sewage. Among them, the waste water mainly contains branches and le...

Problems solved by technology

Among them, the waste water mainly contains branches and leaves that fall off from plants due to watering and irrigation and naturally withered petals, etc., and will affect the water body due to its own slow decay after being discharged into the river water body, producing a large number of bacteria and nitrogen-containing organic matter, making the water body It will become turbid or even produce stench, which will cause eutrophication of the water body, and even the phenomenon of algal bloom may occur, which is harmful to a certain extent.

[0004] At present, there are mainly physical methods, chemical methods and biological methods for wastewater treatment. Among them, the physical method is to use the filter material with adsorption effect to adsorb and filter the sewage to achieve the purpose of removing harmful substances. The long-term use of the filter material makes the filter material also It will cause secondary pollution. If it is discarded directly, it will inevitably pollute the environment.
