人类及牲畜排泄物的综合利用途径

Comprehensive Utilization of Human & Animal Wastes

本文述及厌氧消化技术处理人及牲畜排泄物的生态环境和卫生效果,以及厌氧消化后的沼气、 沼液和沼气发酵残留物的各种可能利用途径。农村处理人畜粪便的沼气技术与农业的可持续发展联系 紧密,能合理兼顾能源、生态(环境和卫生)、社会和经济各个方面的效益,并可因地制宜地建立以沼 气为纽带的各种生态农业模式。在利用厌氧消化技术无害化处理城市公共厕所粪便同时,可开发精制人 粪高效有机液肥。

The paper discusses how to treat human and animal wastes with anaerobic digestion to obtain environmental benefits and realize sanitation as well as various approaches to utilize biogas and biogas fluid and biogas fermentation residues. In rural area biogas technology treating human and animal wastes is closely connected with the development of sustainable agriculture, which can rationally balance energy exploration, environmental protection, social progress and economic results. Moreover, it is possible to establish various eco-agricultural patterns linked with biogas suiting local conditions. Efficient organic liquefied fertilizer is developed from human wastes while anaerobic digestion is adopted to make public-hazard-free excrements from public toilets in cities.
