Multi-functional compound filter materials and preparing method thereof

Abstract

The invention discloses multi-functional compound filter materials, prepared from, 30-35 parts of polypropylene, 8-15 parts of polytetrafluoroethylene, 6-10 parts of rosin, 15-26 parts of activated carbon, 7-11 parts of potassium sulphate, 7-11 parts of muriate of potash, 15-26 parts of zeolite powder, 5-9 parts of absolute alcohol, 4-7 parts of sodium dodecylsulfate and 15-20 parts of water. The multi-functional compound filter materials and preparing method thereof has effects of clearing sewage saline and alkali and clearing peculiar smell in sewage, solves the problem of land salinization, and reduces PH value in water by adding activated carbon, potassium sulphate and sodium dodecylsulfate in the formula so as to clear saline and alkali in water. This way, water will not aggravate salinization in farmland after being irrigated into farmland. Thereby, crops in the farmland can grow up in a normal way, guaranteeing the yield. Rosin and zeolite powder can better purify water quality and clear peculiar smell in water by being added to the formula.

Description

technical field [0001] The invention relates to the technical field of filter materials, in particular to a multifunctional composite filter material and a preparation method thereof. Background technique [0002] Filter material is the general term for water treatment filter materials, mainly used for the filtration of domestic sewage, industrial sewage, pure water and drinking water. With the development of society and economy, water pollution is becoming more and more serious, the composition and content of pollutants are more difficult to control, and the requirements for water treatment technology are getting higher and higher. The original conventional treatment materials can no longer meet the needs of production. Therefore, it is necessary to improve the water quality treatment effect from the source, and improving the performance of the filter material is undoubtedly the most direct and efficient method. At present, the widely used filter materials mainly include qu...

Problems solved by technology

With the development of society and economy, water pollution is becoming more and more serious, the composition and content of pollutants are more difficult to control, and the requirements for water treatment technology are getting higher and higher. The original conventional treatment materials can no longer meet the needs of production. Therefore, it is necessary to improve the water quality treatment effect from the source, and improving the performance of the filter material is undoubtedly the most direct and efficient method. At present, the widely used filter materials mainly include quartz sand filter material, anthracite filter material, volcanic rock filter material and Plant fiber filter materials, etc. These filter materials have their own advantages and disadvantages when used. Generally speaking, improving the use efficiency of these filter materials and reducing production costs are still problems that need to be solved.

[0003] The composite filter material can clean and filter the impurities and harmful substances in the sewage, but the existing composite filter material only cleans the ordinary sewage, but cannot clean the salinity and alkalinity in the sewage. It can eliminate the peculiar smell in the sewage, which will increase the salinization of the farmland when the water is irrigated into the farmland, causing the crops in the farmland to not grow normally, which reduces the yield of the crops
