Compound enzyme preparation for treating rural domestic garbage as well as preparation method and application of compound enzyme preparation

Abstract

The invention belongs to the technical field of garbage treatment, and discloses a compound enzyme preparation for treating rural domestic garbage as well as a preparation method and application of the compound enzyme preparation. The compound enzyme preparation specifically comprises the following components in parts by weight: 15-30 parts of cellulase, 10-20 parts of medium-temperature amylase, 7-15 parts of protease, 8-18 parts of glucanase, 10-20 parts of xylanase, 10-25 parts of lipase, 10-20 parts of pectinase and 15-30 parts of compound enzyme preparation protection liquid. The compound enzyme preparation disclosed by the invention has efficient and specific catalytic activity, cellulose, starch, protein, fat, pectin and other macromolecular substances in the rural household garbage can be quickly decomposed, the use and production cost is low, the use is convenient, and the rural household garbage can be quickly treated.

Description

technical field [0001] The invention belongs to the technical field of garbage treatment, and in particular relates to a compound enzyme preparation for treating rural household garbage and its preparation method and application. Background technique [0002] With the rapid development of my country's economy, the speed of urbanization continues to accelerate, people's living standards continue to improve, the amount of solid waste, especially urban and rural domestic waste, continues to increase, and the pollution to the environment is becoming more and more serious. The treatment and disposal of domestic waste The problem has become a hot spot of close concern to relevant government departments, environmental protection and environmental sanitation management units, design departments, scientific research institutes, colleges and universities, and the industry; seeking an efficient and environmentally friendly domestic waste disposal method is the current domestic ecological...

AI Technical Summary

Problems solved by technology

[0003] At present, the domestic waste treatment methods widely used at home and abroad mainly include: sanitary landfill, composting, incineration, and fermentation to produce biogas; today, with the rapid development of urbanization, it is becoming more and more difficult to select a landfill site , Sanitary landfill treatment occupies a large amount of land resources, and the landfill takes a long time, which is not conducive to the reuse of land resources, and a large amount of leachate, landfill gas and garbage dust will be generated during the landfill process, which will pollute the environment

[0004] The main problem faced by waste incineration is the generation of tail gas from waste incineration, including particulate matter, SO 2 , SO 3 , NOX, HCl, HF, heavy metals, dioxins and other pollutants, among which dioxins are the most concerned and controversial; especially in my country, domestic waste has high moisture and ash content, low calorific value, and requires more Auxiliary fuel, except for a few economically developed cities, the mixed waste in other cities has a low calorific value and high slag content, and the incineration fly ash has not been safely disposed of

[0005] The composting method uses natural microorganisms to degrade the organic matter in the garbage, turning it into a stable humus, which can be used as a fertilizer; but this method has slow heating, long processing time, incomplete fermentation, and cannot effectively kill harmful pathogenic bacteria in domestic garbage. , will also release ammonia, amine salts, sulfides and other harmful substances with a foul smell, which has a strong smell and pollutes the environment
