Description
Technical field
The utility model relates to the refuse disposal system field, and particularly a kind of compost ventilates and leachate collection system.
Background technology
Compost also claims the high-temperature aerobic biological fermentation, is the important process of processing at present organic waste, has been widely used in the recycling treatment of the organic wastes such as domestic waste, municipal sludge, kitchen waste, garden waste and feces of livestock and poultry.To pile rotten organic materials to mix according to a certain percentage with stopping composition in the technique, under suitable moisture content, aeration condition, make microbial reproduction and degraded organic, thereby produce high temperature, kill wherein pathogenic bacteria and weed seed, make organism reach stabilization.Composting Process often is divided into three phases.Fs is middle thermophase, and subordinate phase is hot stage, and the phase III is the stage of becoming thoroughly decomposed.The sign that middle thermophase finishes is heap temperature rise to 45 ℃; The hot stage oxygen consumption rate is high, temperature is high, the volatile organic matter degradation rate is high, stink is dense; Becoming thoroughly decomposed, then temperature was low, oxygen consumption rate is low, voidage increases, soil ulmin increases and stabilization the stage.The control parameter that affects composting process has temperature, water ratio, oxygen level, carbon-nitrogen ratio etc., and temperature wherein, anhydrates and oxygen level is all controlled by ventilation system.Reasonably ventilation not only can improve the composting production quality, and can save energy consumption; Otherwise too high rate of venting not only causes ventilation loss excessive, is unfavorable for keeping heap temperature, and can cause a large amount of nitrogens loss, lowers the fertilizer efficiency of composting production, increases the compost energy consumption; But cross low rate of venting, will reduce the oxygen concn of heap in the body, and then cause heap body part to detest (lacking) oxygen, thereby produce a large amount of foul smell and NOx, methane isothermal chamber gas, bring serious pollution and harm to surrounding enviroment.So ventilating is considered to most important factor in the compositing system.
So the operation of the efficient stable of ventilation system is the key factor of composting process success.The compost draft type mainly contains now: natural ventilation, turning, passive ventilation and forced ventilation.Forced ventilation is applied in most of compositing systems, generally is in the bottom of compost stockpile ventilation gallery or perforated pipe to be set, and then is pooled to blower fan, so that malleation air feed or negative pressure exhausting to be provided.Can be owing to the comparison of ingredients in the rubbish be complicated, particularly Chinese rubbish medium sand class material is many, and the phenomenon that ventilation system is stopped up often can occur, and has caused the treatment effect of many compost treatment engineerings barely satisfactory.
In addition, in most of garbage compost, can produce a certain amount of percolate.If this part percolate can not in time be discharged, can directly affect the water ratio of material, affect the treatment effect of compost.Owing to contain a large amount of biological bacteria in the percolate, anaerobically fermenting occurs in long-time accumulative total, and the secretory product of microorganism can cause hardening of bottom material, the direct interference ventilation effect.For the above problem that has a strong impact on compost engineering effect, research and develop ventilate in a kind of compost treatment engineering of efficient stable and the percolate blowdown system most important.
