灾后重建规划中城市、城镇排泄物的沼气综合应用建议
|
摘要
目前,城市与城镇排泄物被大量浪费,未被合理利用,阻断了生态循环,导致化肥大量增加,污水处理工作量大增,环境污染、能源消耗等日益严重。文章认为应抓住汶川大地震重建带来的契机,将排泄物的沼气池综合利用纳入城乡重建规划,进行试点,逐步推广,促进城乡统筹、节能减排及环境保护。
Waste and unreasonable use of the excreta in cities and towns blocked the ecological cycle, resulted in a substantial increase in fertilizer and sewage treatment. At the same time, environmental pollution, energy consumption grew. Based on this, the purpose of this paper is to take the advantage of the earthquake reconstruction in Wenchuan to bring the comprehensive utilization of waste methane-generating pits into the reconstruction of urban and rural planning, then pilot and gradually spread in order to promote urban and rural harmonious, energy saving and environmental protection.
