- Abstract:
- The total design capacity of the phase Ⅳ expansion project in a wastewater treatment plant in Jiangsu Province is 5.0×104 m3/d. The secondary biochemical treatment system consists of Bardenpho biochemical tank and secondary settling tank, while the advanced treatment utilizes a combination of denitrification filter, high-efficiency settling tank and ultraviolet disinfection. The design effluent quality is required to meet the limit in table 2 specified in Discharge Standard of Main Water Pollutants for Municipal Wastewater Treatment Plant & Key Industries of Taihu Area (DB 32/1072-2018), where COD shall not exceed 41 mg/L. In this project, the biochemical tank, secondary settling tank, sludge pumping house, and secondary pumping house were constructed as a unified facility, the denitrification filter, backwashing blower chamber, and backwashing wastewater tank were integrated into a single system, and micro-sand was introduced into the high-efficiency settling tank. These designs enhanced the treatment capacity while significantly reducing the footprint area of the wastewater treatment plant and addressing the land constraint issue.
