An Overview on Rural Domestic Waste Pollution and Treatment Technologies in China

With the improvement of people's living standards in China, rural solid waste emissions increase sharply. In rural areas where most people live, domestic waste mainly deposited in the open air as one of the most important culprit of rural ecological pollution. Domestic waste is piled up randomly in rural area of China, which enter into river and lake and float on the water, and expand the pollution area. According to data research, The composition of rural domestic waste is mainly kitchen waste, waste plastics, waste paper, broken glass, broken pottery, waste fiber, used batteries and other articles for daily use and other things. There are some differences in component between different areas, while kitchen waste still takes a relatively large proportion. Thus organic matters are one of the most important components of domestic waste, which needs to be considered in devising treatment technology. Landfill, compositing and incineration is three basic methods to treat solid waste. Some featured technology such as biomass gasification, worm composting and anaerobic fermentation is developed to treat rural domestic waste considering its specialties. The treatment of rural solid waste of China is faced with many difficulties like environmental consciousness deficiency. Some technology corresponding to the reality of China needs to be developed and popularized . For the rich organic matters in rural domestic waste and specialties of rural economic situation, technologies need to concentrate on recycling biogas and fertilizers..
