- 摘要:
- 为实现烟台市套子湾污水处理厂厂区臭气的有效去除，基于该厂的水质特点和设计要求，选择BENTAX离子净化法耦合生物滴滤除臭工艺，投资约1亿元，测算运行成本为0.18 元/m3。详细介绍了该厂臭气处理工艺流程、设计参数及运行效果。监测结果表明，BENTAX+生物滴滤工艺能够显著去除污水处理厂产生的臭气，处理后的硫化氢、氨和甲烷等最高浓度分别为0.011 mg/m3、0.20 mg/m3和0.002%，满足《城镇污水处理厂污染物排放标准》（GB 18918—2002）的厂界（防护带边缘）废气排放最高允许浓度的一级标准。目前运行成本约为0.06 元/m3，显著低于预测值。
- Abstract:
- In order to achieve the effective removal of odor in Yantai Taoziwan wastewater treatment plant (WWTP), based on the sewage quality characteristics and design requirements of the WWTP, the BENTAX ion purification method coupled with biotrickling filter was selected. The capital cost is 100 million yuan, and the operating cost is estimated to be 0.18 yuan/m3. The odor removal process, design parameters and operation effect are elaborated. The monitoring results show that the BENTAX and biotrickling deodorization process could significantly remove the odor generated during wastewater treatment, and the maximum concentrations of hydrogen sulfide, ammonia and methane after treatment are 0.011 mg/m3, 0.20 mg/m3 and 0.002% respectively, meeting the first level criteria in Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002). At present, the operating cost is about 0.06 yuan/m3, which is lower than the estimated value.
