Problems solved by technology

The technology of microbial decomposition and treatment of polluted water is more and more widely used. In the prior art, the types of microorganisms in common microbial water purification agents are relatively single, and the decomposition and treatment of water are not thorough. Therefore, there is an urgent need for a decomposing treatment of water. Good pollution effect, economical and environmentally friendly composite micro-composite microbial water purifier
[0005] The Chinese patent application with the publication number CN 104445635 A discloses a high-efficiency biological water purifier and its preparation and use method. The composite micro-composite microbial water purifier is composed of microorganisms, biological enzymes and flocculants. The microorganisms are It is composed of Bacillus, nitrifying bacteria, photosynthetic bacteria, streptococcus, actinomycetes, phosphorus accumulating bacteria and yeast. The biological enzyme is composed of lipase, amylase, phytase, pectinase, cellulase, lignin Composed of enzyme mixture, the flocculant is composed of polyaluminum chloride, polyferric silicate, and polyacrylamide. Since the composite microbial water purifier is directly put biological enzymes into the water, it is difficult to ensure the activity of the enzymes and the purification effect is difficult to guarantee

Abstract

The invention discloses a compound microorganism water purifier and a preparation method and application thereof. The compound microorganism water purifier is prepared from, by weight, 20-35 parts ofpotassium peroxymonosulfate, 60-80 parts of a cyclodextrin microorganism compound, 40-60 parts of modified titanium dioxide waste residues and 10-20 parts of sodium copper chlorophyllin. According tothe compound microorganism water purifier, water disinfection, water harmful matter pollution degradation, water excessive ammonia nitrogen organic matter conversion and water micro-ecology balance restoration can be fundamentally achieved, the effects of purifying water, increasing oxygen and adjusting the flora are achieved, secondary pollution is avoided, and the advantages of being efficient and environmentally friendly are achieved. The compound microorganism water purifier can be applied to purifying urban sewage or industrial waste water or agricultural sewage, and is wide in application range.

Description

technical field [0001] The invention relates to the technical field of microorganisms and water body purification, in particular to a composite microbial water purifier and its preparation method and application. Background technique [0002] Water treatment has always been one of the most important issues in the world. Globally, water consumption is increasing rapidly everywhere. At the same time, the problem of water pollution has become increasingly serious, and serious contradictions between supply and demand of water resources have emerged in many regions and countries. Therefore, how to improve the sewage treatment capacity so that it can be used here is extremely important. At present, the main sources of water pollution in the world mainly include industrial pollution, agricultural pollution and domestic sewage. [0003] There are five main hazards caused by various sewage, namely pathogen pollution, aerobic organic pollution, eutrophication pollution, stench and ...
