地下式污水处理厂用地指标分析及节地设计方向
- Title:
- Analysis of Land Quota and Land Conservation Design Direction of Underground Wastewater Treatment Plant
- 摘要:
- 针对目前国内地下式污水处理厂用地控制指标尚无相关标准的现状，通过对国内113座已建和在建地下式污水处理厂的实际用地指标进行统计分析，并结合理论计算，提出了不同规模地下式污水处理厂的用地按0.35~1.20 m2/（m3·d-1）指标范围进行控制的建议。对于地下式污水处理厂的节地设计，结合具体的工程案例，提出了工艺路线选择、工艺参数优化、总体布置节地和地块综合开发利用节地等设计方向。具体的工程设计中，需要综合考虑节地、安全、成本和管理等多方面因素，以实现在项目特定条件下最大程度节地。
- Abstract:
- At present, there is no relevant standard for land control quota of underground wastewater treatment plant in China. Based on the statistical analysis and theoretical calculation of the actual land quota of 113 underground wastewater treatment plants have been built and are under construction in China, the paper suggested that the land quota of different scale underground wastewater treatment plants should be controlled in the range of 0.35-1.20 m2/(m3·d-1). For land conservation design of underground wastewater treatment plant, this paper proposed the design directions of process route selection, process parameter optimization, land conservation by overall layout optimization and land conservation by comprehensive development and utilization based on specific engineering cases. In specific engineering designs, it is necessary to comprehensively consider many factors, such as land conservation, safety, cost and management, so as to achieve the maximum land conservation under the specific engineering conditions.
