- 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.
