农村污水特点Features of the Rural Wastewater

• 水量小• Small flow rate

• 污水水质、水量波动很大• The quality and flow of wastewater fluctuate intensely.

• 由于处理规模小,工程建设费和运行费相对偏高• High cost of project and operation because of the small

scale of WWTP

• 经济承受能力弱,可供选择的技术和设备少• Lack of alternative technologies and instruments because

of the backward economy

农村污水处理面临问题的讨论Discussion for the Problem of the Rural Wastewater

Treatment• 排水系统:因地制宜,尽量采用分流制或截流式合流制,如果条件不

允许,可采用其他经济合理的排水系统方案。• Wastewater Sewer System: It’s better using the Separate

Sewer system or Combined Sewer Overflow system. But may use other economy sewer system when condition no allowed.

• 排放标准:由于经济水平较低,避免“建得起,用不起”的情况,可根据情况调整排放标准。

• Wastewater Emission standards: Lower down the Emission standards for rural WWTP because of backward economy.

• 污水处理工艺 : 充分考虑水质水量变化大的特点,选择合适的工艺• Treatment Process : Chose suitable process by Considering

changing a lot of water flow and quality.• 污水处理厂的经济性• Economical Efficiency of the rural WWTP

农村污水处理工艺Process for Rural Wastewater Treatment

• 适合规模小、水质水量变化大、经济的工艺:• Process suitable for Small scale, diversification of wastewater

quality and flow, and economy:– 生物接触氧化– bio-contact oxidation

– 厌氧生物滤池– Anaerobic Bio-filter

– 膜生物反应器– Membrane Bioreactor

– 人工湿地等 – wetland – ……

农村污水处理厂面临的问题Problem of the Rural WWTP

• 问题 /Problem:– 进水负荷变化很大,出水却要达标。– Inflow load fluctuate intensely, but effluent should be up to the

standards.– 规模小,吨水处理费用高– Small scale, high cost for treating each ton of wastewater

• 解决方案 /Solutions– 选择合适的工艺以适应农村污水– Select suitable process for the rural WWTP– 集中处理,并根据进水负荷实时调整工艺参数,以适应农村污水– Adjust the process parameter from time to time according to the

inflow load
