| Abstract: |
| The annual generation amount of household waste in the villages and towns of China has exceeded that in cities, whereas its treatment level is low by now. Based on the survey about the generation of household waste in domestic villages and towns, the present work analyzed the waste treatability. Combining with the investigation on the typical patterns of their treatment methods in China and in the world, the work focused on how to select appropriate pattern for the treatment of household waste in Chinese villages and town. By comparing the environment, resource and economy of different patterns, the work suggested to separately use the patterns of “completely centralized” and “cooperation among villages, towns and counties”, depending on the area density of their waste generation. The “cooperation” pattern is effective to coordinate the environmental and economic benefits of local household waste treatment in low population or waste generation density areas. The suitable technology route for implementing the “cooperation” pattern is firstly to in-situ sort the household waste by collection personnel, secondly to in-situ treat the biodegradable fraction and in-situ landfill the sand and soil fraction, and at last to transport the rest fractions to counties or cites for centralized treatment. |
