Water purifying agent for rapid treatment of industrial wastewater and preparation method thereof

Abstract

The invention relates to a water purifying agent for rapid treatment of industrial wastewater and a preparation method thereof, wherein the water purifying agent comprises the following components inparts by weight: 20-35 parts of a nano diatomite powder/cellulose composite material, 5-10 parts of alkyl glycoside or derivative surfactant thereof, 60-75 parts of a flocculating agent and 2-6 partsof nitrifying bacteria. The water purifying agent prepared by the invention is simple in components and reasonable in proportion, does not contain heavy metal components in the formula, is mostly a natural compound, is an environment-friendly water purifying agent, and avoids secondary pollution to a water body; cellulose and diatomite powder are subjected to nanocrystallization and compounding, have huge specific surface area, can adsorb a large number of polluting organic matters, are fully mixed with specific contents of raw material components, and have the effects of rapid sedimentation,decolorization and COD removal; and alkyl glycoside or derivatives thereof are added, so that the water purifying agent has sterilization and disinfection effects on the water body, can effectively kill bacteria and microorganisms in the water body, and avoids water body pollution caused by mass propagation.

Description

technical field [0001] The invention relates to the field of industrial wastewater treatment, in particular to a water purifying agent for rapid treatment of industrial wastewater and a preparation method thereof. Background technique [0002] Water is the source of life, and water resources are the prerequisite for the survival of human society and are directly related to the sustainable development of society. However, with the rapid development of my country's national economy, a large amount of industrial wastewater, medical wastewater, urban wastewater, agricultural wastewater, etc. have been produced, and water pollution has become increasingly serious, seriously affecting people's physical and mental health and living environment. Coagulation treatment of wastewater by water purifier is one of the most commonly used means in water treatment. Water purifiers are agents that can react with other impurities in water when put into water, mainly for the purpose of water p...

AI Technical Summary

Problems solved by technology

Even after biochemical treatment, the chromaticity multiple of the effluent of the secondary sedimentation tank is still high, the biodegradability is poor, and COD is difficult to remove

However, direct injection of water purification materials has the disadvantages of single function, low removal rate of COD, slow sedimentation rate and poor decolorization.
