Description
Technical field
The utility model relates to the processing of the high concentration organic sewage that produces in changing food waste (being commonly called as swill) that restaurant, dining room produce and worker, the agricultural production process, particularly relates to a kind of changing food waste high speed biological treatment system.
Background technology
The city changing food waste is the source that produces sewer oil, rubbish pig at present, and these rubbish enter people's dining table from various channels, have seriously jeopardized the healthy of the people.It is reported that restaurant, Zhengzhou City, dining room produce about 500 tons of leftovers leftovers changing food waste every day, add the changing food waste in restaurant, meal kitchen, the dining room sewage effluent, prediction is up to 700-800 tons; Annual restaurant, the whole nation, dining room changing food waste generation have reached 60,000,000 tons.Changing food waste, sewer oil have caused the great attention of central authorities and local governments at all levels to the impact of food safety, No. 36 files of General Office of the State Council's on July 13rd, 2010 are about " strengthening the suggestion of sewer oil regulation and kitchen castoff management ", require prefectures and cities with mayor's responsibility system, coordinate each functional department and strengthen the changing food waste management.China's changing food waste harmless treatment is started late, nearly two be only in indivedual cities such as Xining, rather sprinkle, cities such as Beijing, Shanghai are at the early-stage.Wherein administer the changing food waste effect best be the Xining, " Xining pattern " is that government specifies professional enterprise to establish changing food waste treatment plant to handle leftovers leftovers changing food waste, 200 yuan one ton of changing food waste government finance subsidies of the every processing of enterprise.Prefectures and cities learn " Xining pattern " one after another.
" but Xining pattern " has following " congenital " deficiency: 1, the changing food waste utilization ratio is low, and the processing cost height is handled one ton of changing food waste enterprise and will be lost more than 150 yuan.The at present domestic changing food waste treatment technology that generally adopts is a biochemical process, changing food waste treatment plant collects behind the changing food waste through physical and chemical processes such as oil removing, dehydration, oven dry, solid matter is made animal-feed, and sewer oil becomes industrial chemicals, and sewage is discharged through processing up to standard back.Establish that changing food waste treatment plant investment is big, processing cost is high, the changing food waste utility value is low, and the waste water that produces in the processing also needs processing up to standard, and changing food waste solids content 10-12%, large amount of sewage need handle has increased no small processing costs; Changing food waste causes secondary pollution easily in collection, transportation, processing, blowdown process.2, to handle fraction of coverage low for changing food waste, can only handle the restaurant, dining room leftovers leftovers changing food waste can not be handled the changing food waste in restaurant, meal kitchen, the dining room sewage effluent, can not block sewer oil, rubbish pig leak fully.More crucial reason is that changing food waste treatment plant does not have the government finance subsidy to be difficult to operation, so " Xining pattern " promotes difficulty.With the Zhengzhou City is example: 15 mu of the occupations of land of building up in September, 2007, more than 2,380 ten thousand yuan of total infusion of financial resourcess, the changing food waste treatment plant that design day is handled 50 tons of changing food wastes, losses due to poor management always after succeeding in the test run are finally but subsidized and were forced to stop production nearly 3 years because of can not get government finance.
The changing food waste biological treatment is under certain temperature, humidity, potential of hydrogen and anaerobic condition, and producing a kind of through various microbial fermentations, Decomposition is the waste disposal method of the mixed combustible gas body (biogas) of main component with methane.The byproduct biogas that the changing food waste biological treatment produces can be used as the energy, and natural pond fertilizer can be used as organic fertilizer and is used for the alternative chemical fertilizer of farm crop, and sewer oil can be used as biodiesel raw material, realizes garbage as resource fully.The development and use of rubbish biological treatment technology West Europe early; be that the rubbish biological of representative is handled company's treatment technology and led world trends with Germany; built up at present the rubbish biological treatment plant more or less a hundred that puts into effect in the world; treatment system year, processing power was all more than 1,000,000 tons, made positive contribution to promoting the environment protection and the utilization of resources.But, establish a rubbish biological treatment plant and need invest several hundred million units, improved the access threshold of large scale rubbish biological treatment, suppressed the rubbish biological treatment technology greatly and applied.China's organic waste biological treatment at present mainly is used in the biological treatment that fowl is raiseeed fowl and animal excrement, organic sewage and industrial organic sewage that professional raiser or farm produce, and processing power dry matter content every day is several tons scale.
