Description
Technical field
The invention belongs to environmental protection technical field, be specifically related to a kind of bacteriostatic agent and preparation and application thereof of controlling the discharge of Domestic Waste Collection fortune process dusty gas.
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 exceedes 10,000 tons, and so a large amount of rubbish will pass through garbage-compressing transfer conventionally, then receipts are transported to destructor plant.Household garbage-compressing transport process is as the binding site that connects 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, foul odour, airborne dust, the sewage that garbage collecting and transferring produces and the insect pest (mosquitos and flies) thereupon bringing, be a troubling problem, especially from city neighborhood, fortune station is received in the transfer close to always, and what the public complained more and strong reaction is foul odour.Therefore,, for solving the waste transportation problem that disturbs residents, seek effective and practicable peculiar smell control technology imperative.
In rubbish, contain a large amount of carbohydrate, protein and fat, in anoxic process, can produce multiple smell substance, 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 grown, also can produce methane isothermal chamber gas.Smell substance belongs to colourless gas mostly, its odor threshold extremely low (mostly being ppb level), has strong impulse stench taste, and some also has larger toxicity, and very easily combine with airborne moisture, grit, enter harm health with respiratory system.In order to improve resident living environmental quality, stop air pollution hidden danger, to improve city image, the smell pollution control of garbage collecting and transferring process has become one of some environmental problems regional urgently to be resolved hurrily at present.
The air pollution control measure of garbage collecting and transferring process mostly is the closure equipment that adopts, adopt once in a while screening agents such as spraying plant extraction liquid, these methods have played certain effect to alleviating 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 current this field and pollute the development trend of controlling.
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.Can be divided into two large classes by its antibacterial mechanism.
(1) oxidized form bacteriostatic agent.Common have liquid chlorine, clorox, bromine, ozone, chloramines, chlorated fulminuric acid and salt, a 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, dodine hydrochloride, quaternary alkylphosphonium salt etc.).
Above bacteriostatic agent is many because extensive higher, the antibacterial broad spectrum activity of use cost is poor or have secondary pollution (as hypochlorous acid is pressed, liquid chlorine, bromine, chloramines, chlorophenol, heavy metallic salt etc.), thus in disposal of refuse place seldom for smell pollution control.
The mushroom that causes waste odor to produce mainly concentrates on strict anaerobes, to gram-positive bacteria, and Gram-negative bacteria, bacterial spore and fungi, acid-producing bacteria, methanogen etc., therefore, choice for use, for the bacteriostatic agent of such bacterium, can effectively be controlled smell pollution.
Summary of the invention
The object of the invention is to overcome defect of the prior art, a kind of bacteriostatic agent environmentally friendly, that the good plant resource class compound preservative of anaerobic bacteria inhibition is polluted as the gas with foreign flavor of garbage collecting and transferring process is provided, and its preparation method and using method are further provided.Bacteriostatic agent of the present invention is for suppressing the growing of anaerobic fermentation bacterium of house refuse, and this bacteriostatic agent, for the control of distributing of garbage collecting and transferring process smell substance, is avoided the generation of smell substance, and had sterilizing effect concurrently.
The bacteriostatic agent of control Domestic Waste Collection fortune process dusty gas of the present invention discharge 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.
More specifically, described plant material is pressed dry weight basis, comprises the component of following weight portion:
