Yield is surprising.Beijing produces kitchen garbage about more than 1600 ton daily, is responsible for what is completed according to University Of Chongqing《Chongqing City
City kitchen garbage yield investigation and analysis of physical and chemical property report》, the daily yield of Chongqing kitchen garbage in 2007
About 1000 tons；By 2003, the kitchen garbage that Shanghai City is produced daily was also up to 1100 tons or so.
Organic solid castoff necessarily leads to odor pollution in biological treatment process.Odor pollution is one kind of atmosphere pollution
Form, but due to its particularity, many countries treat as single-row public hazards, belong to the typical public hazards in seven kinds of the world today (big
One of gas pollution, water pollution, soil pollution, noise pollution, vibration, land subsidence, stench).Foul gas is directly acted on
The smell of people is simultaneously damaged by breathing to human body, the increasingly raising with people to environmental quality requirement, and people are to various
The discontented mood that stench is caused and the ratio complained also more and more higher, especially in some developed countries, the complaint to stench
More than 90% always complained beyond environmental pollution.In the area such as Japan and Hong Kong, odor pollution has turned into the main ring that the public complains
Border problem.In recent years, China cities and towns odor pollution event frequently occurs, and stench is complained shared by whole environment tip-offs about environmental issues
Ratio occupies second, and odor pollution is increasingly becoming a serious society and environmental problem.Odor pollution preventing and treating has caused China
