摘要:
对规模为45×104 m3/d的某污水厂进行异地新建，出水标准由一级B提高至准Ⅳ类标准。新厂选用污泥浓度高、出水水质优、运行稳定的“速沉池+多级AO+矩形周进周出二沉池+DN生物滤池+高效澄清池+V型滤池+臭氧催化氧化+紫外消毒”处理工艺。工程设计总规模为60×104 m3/d（其中一期为45×104 m3/d），占地面积33 hm2，一期工程费16.79亿元。实际运行结果表明，各出水指标可稳定达到天津市地标A标准（准Ⅳ类标准）。该工艺可有效应对北方地区污水的高排放标准处理，该污水厂实际吨水电耗0.27 kW·h/m3，运行成本约1.31元/m3，属低能耗环境友好型污水厂。
Abstract:
A wastewater treatment plant with a scale of 45×104 m3/d was rebuilt in a different place, and the discharge standard was raised from first level B limit to quasi class Ⅳ limit. The treatment process of the new plant was characterized by high sludge concentration, high effluent quality and reliability, which consisted of rapid sedimentation tank, multi-stage AO, rectangular peripheral-feed peripheral-overflow secondary clarifier, DN biofilter, high-efficiency clarifier, V-type filter, ozone catalytic oxidation and UV disinfection. The total design scale of the project was 60×104 m3/d (phase Ⅰ project was 45×104 m3/d), the footprint area was 33 hm2, and the investment of phase Ⅰ project was 1.679 billion yuan. The actual operational results showed that each index in effluent stably met the A limit specified in the Tianjin local discharge standard (quasi class Ⅳ standard). The process was effective in treating wastewater to meet a high discharge standard in northern China. The actual unit power consumption was 0.27 kW·h/m3, and the operating cost was approximately 1.31 yuan/m3, indicating that the wastewater treatment plant was energy consumption and environmentally friendly.
