Description
Technical field
The present invention relates to a kind of waste disposal method, be specifically related to the method for comprehensive regulation percolate and garbage odor.
Background technology
The quick growth of domestic waste has become the thorny problem that countries in the world urban development generally faces.In China, the domestic refuse of nearly 1.5 hundred million tons is had to produce every year.Domestic refuse, in the prevention and cure of pollution of transfer and landfill process, is particularly disliked, percolate is controlled, become the problem great deeply concerned that domestic rubbish disposal is disposed.Compared with the sorted rubbish of most of developed country, China's domestic refuse has the features such as Combination is high, water ratio is high, organic composition is high, be easy to especially form percolate and odor pollution air, soil, water source, Environmental capacity and intractability are also very large.
Because domestic refuse is in biodegradation process, the particularly katabolism of protein, carbohydrate etc., various foul gas in meeting sustained release.The main component of the foul gas of domestic refuse release includes 5 classes: 1. sulfocompound, as hydrogen sulfide, thiomethyl alcohol, dimethyl sulfide, dimethyl disulfide etc.; 2. nitrogenous compound, as ammonia, amine, indoles etc.; 3. halogen and derivative, as chlorine, halohydrocarbon etc.; 4. hydro carbons and aromatic hydrocarbon; 5. oxygen-bearing organic matter, as alcohol, phenol, aldehyde, ketone etc.Various component is not only relevant with concentration to the contribution margin of stench, has substantial connection with its olfactory threshold.
At present, functional microbial flora (EM bacterium etc.) is mainly comprised both at home and abroad about domestic refuse original position reodorant, the agent of conventional oxidation chemical deodorizing, plant extract agent (essentialoil), microbial inhibitor and various stench screening agent.Wherein traditional chemical oxidation style is by adding various oxygenant, comprise H2O2, KMnO4, FeCl3, Fe2 (SO4) 3 etc., to improve the redox potential in domestic refuse, reduce the activity of sulphate reducing bacteria, and the foul gass such as oxidation of sulfureted hydrogen, with reduce foul gas in domestic refuse release (as Chinese patent 201010166835.6 the odor removal that provides and method thereof).But, traditional chemical oxygenant is difficult to improve the redox potential in rubbish system, and does not possess oxidation selectivity due to it, easily by non-in rubbish system cause smelly reducing substances consume, therefore there is action time short, the problems such as additive amount of medicament is larger.Especially for the refuse disposal system of middle large-scale city, need to carry out free of discontinuities sprinkling, deodorizing to domestic refuse in the step such as transhipment, transferring storage in process domestic waste process, comparatively large to the demand of reodorant, adopt traditional chemical oxidizing agent deodorizing that deodorizing cost will be caused to be difficult to control.Biological process refers to and spray certain micro-organisms in domestic refuse system, as effective microorganism (EM bacterium) and other Deodorizing Bacterias screened, utilize the Degradation of microorganism, repugnant substance decomposition and inversion is become innoxious substance, thus reduce the release of foul gas in domestic refuse.Although utilize microorganism to carry out deodorizing to domestic refuse achieved certain achievement, its problem that there is breeding strain and preserve the aspects such as difficulty, Deodor effect and reliability are not strong.Especially, under different areas, Different climate environment, its inside of deodorizing microorganism all can change to the metabolic pathway of organic pollutant, metabolic efficiency and product etc., macroscopical then under showing as varying environment reodorant have inconsistent deodorizing effect, cause its scope of application of prior art biological deodorant narrower, or needed to tame it, screen before deodorizing process.Meanwhile, existing biological deodorant initially makes it in deodorizing, is in the adaptive phase, needs can to enter logarithmic phase through overactivation, stationary phase plays deodorizing effect, cause its deodorizing treatment time longer.Chinese patent 201210191084.2 discloses a kind of method utilizing percolate domestication soil bacteria to prepare reodorant, can tame and filter out the microorganism species that can be used for deodorizing quickly and efficiently, but the method still needs to screen soil microorganisms and tame, and due to microbe-derived instability, cause the deodorizing effect of the method unstable.
In addition, the percolate that rubbish produces also is one of source of domestic refuse stink, and prior art lacks a kind of method of comprehensive treating process percolate and stink, percolate process is separated with deodorizing process and administers respectively, with high costs and poor effect.
Therefore, the domestic refuse deodorizing method that cost of development is cheap, easy and simple to handle, reliability is strong, controls to have very important effect to the stench of domestic refuse transhipment station, transport chain and landfill yard.
