Description
Technical field
The utility model relates to a kind of rubbish deodoration system, is specifically related to the system of a kind of 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 controls in the prevention and cure of pollution, particularly stench of transfer and landfill process, has 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, is easy to especially form stench, and 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, comprising H
2o
2, KMnO
4, FeCl
3, Fe
2(SO

3deng, 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.
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.
Utility model content
In view of this, the utility model discloses a kind of with low cost, easy and simple to handle, domestic refuse deodorizing that reliability is strong, percolation liquid treating system.
The purpose of this utility model is achieved through the following technical solutions:
A system for comprehensive regulation percolate and garbage odor, comprises leachate purification unit and deodorization unit, and described leachate purification unit comprises rubbish heap buried module, leachate collection module and Multi-stage downstream formula biochemical treatment module; Described Multi-stage downstream formula biochemical treatment module comprises multiple treating pond connected successively, biofilm packing is provided with in treating pond, described deodorization unit is comprised the percolate acquisition module, the reodorant configuration module be connected with percolate acquisition module and the reodorant be arranged in rubbish heap buried module that are connected by the first pipeline with Multi-stage downstream formula biochemical treatment module and sprays module, and reodorant spray module is connected by second pipe with described reodorant configuration module.
Because domestic refuse all can produce a large amount of percolates when transfer, transhipment, landfill, its kind of stink substance in areal contained by percolate, concentration and domestic refuse etc. are more consistent, and deodorizing process and landfill leachate treatment integrate by the utility model especially.First the utility model adopts microorganism to purify percolate in Multi-stage downstream formula biochemical treatment module, through the domestication of percolate, the microbial population of wherein surviving is to kind, the concentration of pollutent in percolate, and even the weather of environment, oxygen level etc. have higher adaptability, and intracellular organic metabolism approach also has higher degrading activity for the organic pollutant in this area's domestic refuse; The utility model utilizes percolate acquisition module to gather percolate and configure reodorant in reodorant configuration module, because the microbial bacteria in prepared reodorant is in highly active Exponential growth stage or the stage of stable development, without the need to efficient degradation can be carried out to the stink substance in domestic refuse through long activation treatment, significantly can eliminate the stink substance in rubbish at short notice, reduce the stink in environment.Meanwhile, landfill leachate treatment unit also can be deodorizing process and provides high vigor bacterial classification continuously, and cost can be split in percolate process and deodorizing process two portions respectively, and final realization reduces costs, improves the object of odor removal efficient.Adopt system of the present utility model, not only can purify percolate and refer to and reach emission standard, prevent it to the pollution of natural water; More can improve the Air quality in waste transportation, heap buried process, the pollution that minimizing refuse collection and treating processes cause air, utilize the principle of systems engineering, finally realize the innoxious landfill disposal to domestic refuse.
