Description

A kind of weight control method of the microorganism decomposition technique for organic matter and its control System
Technical field
The present invention relates to organic matter decomposition technique fields, are to be related to a kind of microorganism for organic matter point specifically Solve the weight control method and its control system of technique.
Background technique
House refuse is to pollute urban and rural environment, influence people's lives and perplex the global social concern of urban development.Mesh Before, China generates 66,000,000 tons of kitchen garbages every year, and increases with annual 10%.Annual processing cost is up to 50,000,000,000 or more.Meal Kitchen garbage disposal ability wretched insufficiency, domestic harmless handling rate is only 10% at present.Kitchen garbage promise processing is not good at then can be to water Body, soil, atmosphere generate pollution.Promise kitchen garbage reflux dining table can then damage resident's health.In kitchen garbage Rubbish source of generation is handled with microorganism decomposition method come volume reduction decrement, to reduce garbage collection, transport, treatment process In on soil, environment, health and it is financial caused by influence, not only have the economic benefit of highly significant, there are also far-reaching societies Benefit.
In China, realize " innoxious, minimizing, recycling and it is innoxious under the premise of it is cost effective " be garbage disposal Target.China's municipal refuse mainly passes through landfill, compost and burning and is handled at present, and more regions still generallys use directly Landfill method.It is easy to cause the secondary pollution of environment and groundwater resources.Organic domestic waste and animal wastes, in microbial action Under, biochemical reaction can be carried out, a kind of substance of similar humus soil is eventually formed, can serve as fertilizer or improvement soil. It is more than the month to generally require 3-4 for traditional composting process, is easy pollution environment, smelly, and the time is long.Many sections in recent decades Scholar one until power in developing a kind of modern science and technology, correct Traditional compost method there are the problem of.
The processing equipment or control technology using microorganism decomposition organic matter currently on the market mainly has a following two categories: one Class is to need outside plus either physically or chemically, such as crush, is dry, compression and chemical immersion, could help microorganism Complete entire organic waste decomposable process.The shortcomings that this method, is: sewage discharge can be generated, it is smelly.Another kind of is using temperature Spend control method, but at present it is all using temperature controlled method come the processing equipment and processing method of decomposing organic matter, all Design effectively and intelligent control, base are not carried out according to the growth of microorganism, breeding, the biological law of decomposition and temperature change Using thermostatic control on this, sets heating temperature and click through trip temperature switch control, keep the temperature at a temperature region. The shortcomings that this method, is: cannot reflect growth, breeding and the material decomposing state of microorganism during microorganism decomposition comprehensively Requirement to different temperatures region causes organic matter to decompose insufficient, and decomposition efficiency is low, is extremely difficult to without sewage discharge, process In be easy to happen stink.This is also the main reason for miniaturization, source processing equipment are rarely employed currently on the market.
The invention mainly relates to be that aerobic decomposition is carried out to organic matter by microorganism.Aerobic decomposition is by organic materials It is mixed in a certain ratio with filler material, strain and after mixing evenly is added, pass through the corresponding temperature of control, humidity and ventilation oxygen supply Condition releases a large amount of enzyme using strain, and larger molecular organics are decomposed into low point of the short chains such as sugar, fatty acid and amino acid Sub- organic matter, strain is discharged as nutrient, gas and biological heat energy, and the high temperature of generation kills pathogen therein and miscellaneous Grass seed makes organic matter reach stabilisation.
Currently, all using high temperature aerobic composting mostly.Aerobic decomposition temperature is high, generally at 40-80 DEG C, therefore also known as high temperature Compost.Since During High-Temperature Composting can kill pathogen to the maximum extent, meanwhile, final product fast to the degradation speed of organic matter It is water, carbon dioxide, heat, humus.Strain is bred rapidly with geometric progression simultaneously in decomposable process.Such strain can week And it renews ground constantly " eating " and falls the organic waste newly put into.With the accumulation of metabolite, strain can gradually aging, generally process It the 1-3 month needs to put into new strain in microorganism organic garbage disposal.Usual strain is to the decomposition rate of organic waste 12~48 hours, about 24 hours average, residue rate is 10%~20%.The residue that organic matter is generated after microbiological treatment can As organic fertilizer or feed addictive, the moisture of generation by surface evaporation, circulation damping or can be expelled directly out, generation H may be contained in gas2S、NH3Equal odorants, can make the gas of discharge without malodorant by pyrolytic deodorization Matter.
In equipment in the prior art using microorganism decomposition organic matter, there are no any equipment or method using weighing Sensor carries out process control.Without being using the shortcomings that weighing sensor acquisition control: it is micro- that organic waste solution can not be understood Biological decomposition state can not effectively control the moisture content generated in decomposition.It is much that the water leaching method used is come currently on the market As a result control water inlet and draining generate large amount of sewage discharge, cause secondary pollution, decomposable process is easily smelly, micro- life to control humidity The object flora service life is short.
