Description
Technical field
The invention belongs to environmental protection technical field, be specifically related to a kind of bacteriostatic agent and the preparation and application thereof that control Domestic Waste Collection fortune process contamination gas discharging.
Background technology
Along with expanding economy, the raising of people's living standard, the growth of urban population, the expansion of urban area, the generation of municipal refuse increases year by year.In Shanghai, the Shanghai City house refuse daily output is more than 10,000 tons, and so a large amount of rubbish usually will through garbage-compressing transfer, then receives and be transported to destructor plant.Household garbage-compressing transport process is as the binding site connecting rubbish source of generation and end disposal system, and its effect is more and more obvious, is the requisite link that current municipal refuse is cleared.But, the foul odour that garbage collecting and transferring produces, airborne dust, sewage and the insect pest (mosquitos and flies) thereupon brought, be a troubling problem always, especially receive fortune station from the transfer close to city neighborhood, what the public complained more and strong reaction is foul odour.Therefore, to disturb residents problem for solving waste transportation, it is imperative to seek effective and practicable peculiar smell control technology.
Containing a large amount of carbohydrate, protein and fat in rubbish, multiple smell substance can be produced in anoxic process, mainly contain ammonia (NH
3), hydrogen sulphide (H
2s), methyl mercaptan (CH
3sH), methyl sulfide CH
3sCH
3), trimethylamine ((CH

3), lower alcohol and fatty acid etc., the rubbish that the anaerobic fermentation time is longer, also can produce methane isothermal chamber gas.Smell substance belongs to colourless gas mostly, its odor threshold extremely low (mostly being ppb level), have strong impulse stench taste, some also has larger toxicity, and very easily combine with the moisture in air, grit, enter harm health with respiratory system.In order to improve resident living environmental quality, stopping air pollution hidden danger, improve city image, the smell pollution of garbage collecting and transferring process controls to have become one of environmental problem that some areas are urgently to be resolved hurrily at present.
The air pollution control measure of garbage collecting and transferring process mostly is and adopts closure equipment, adopt screening agents such as spraying plant extraction liquid once in a while, these methods serve certain effect to alleviation peculiar smell and dust pollution, but all can not fundamentally eliminate peculiar smell and contamination by dust, smell substance still leaks from gap.Therefore, develop the effective pollution control technology of a kind of garbage collecting and transferring process peculiar smell, meet the development trend of this field Environmental capacity current.
Bacteriostatic agent is often referred to the material of energy bacteria growing inhibiting.Daily bacteriostatic agent spininess is to Escherichia coli, staphylococcus, candida albicans and some fungi, be used for preventive medicine scope, consider bactericidal property simultaneously, be usually used in gynaecologic washing lotion, wet tissue, sanitary napkin, oral-cavity article, hand cleanser, melon and fruit fresh-keeping with sterilization, environment disinfected etc.Two large classes can be divided into by its antimicrobial mechanism.
(1) oxidized form bacteriostatic agent.Common have liquid chlorine, clorox, bromine, ozone, chloramines, chlorated fulminuric acid and salt, hydantoin halides etc.
(2) Non-oxidized bacteriostatic agent.Common have chlorophenols, quaternary ammonium salt, isothiazolinone, Chinese cassia tree aldehydes, heavy metallic salt (as copper sulphate, copper citrate), other organic matter classes (as metronidazole, sevin, fatty acid amine, dodecyl guanidine hydrochloride, quaternary alkylphosphonium salt etc.).
Above bacteriostatic agent many because of extensive use cost higher, antibacterial broad spectrum activity difference or exist secondary pollution (as hypochlorous acid by, liquid chlorine, bromine, chloramines, chlorophenol, heavy metallic salt etc.), thus seldom control for smell pollution in disposal of refuse place.
The mushroom causing waste odor to produce mainly concentrates on strict anaerobes, and to gram-positive bacteria, Gram-negative bacteria, bacterial spore and fungi, acid-producing bacteria, methanogen etc., therefore, choice for use, for the bacteriostatic agent of such bacterium, effectively can control smell pollution.
Summary of the invention
The object of the invention is to overcome defect of the prior art, a kind of bacteriostatic agent that is environmentally friendly, that pollute as the gas with foreign flavor of garbage collecting and transferring process the good plant resource class compound preservative of anaerobic bacteria inhibition is provided, and further provides its preparation method and using method.Bacteriostatic agent of the present invention is for suppressing growing of the anaerobic fermentation bacterium in house refuse, and this bacteriostatic agent distributes control for garbage collecting and transferring process smell substance, avoids the generation of smell substance, and has sterilizing effect concurrently.
The bacteriostatic agent of control Domestic Waste Collection fortune process contamination gas discharging of the present invention is plant extraction liquid, and the plant material component of described extract comprises: peppermint, galingal, Chinese honey locust, Radix Glycyrrhizae, Fructus meliae toosendan and vomiting nut.
