- Abstract:
- The process of a semi?underground wastewater treatment plant (WWTP) with scale of 5×104 m3/d in Guangdong Province consists of modified AAO, micro-flocculation and fiber turntable filter. The setting of landscape cover, the reasonable distribution of comprehensive building, electric distribution room and the main factory building, and the highly intensive combined design of the internal structures solved the difficulties in adjacent to the residential area, scattered land and serious shortage of footprint area. The operational results show that the effluent quality is better than the stricter values of the first level A limit specified in Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002) and the first level limit during the second period specified in the Guangdong local standard of Discharge Limits of Water Pollutants (DB 44/26-2001). The boundary environment of the plant is coordinated with the surrounding area. The wastewater unit investment is 3 334 yuan/m3, and the variable cost is 0.57 yuan/m3, indicating that good economic benefit is obtained.
