- Abstract:
- The design scale of the first phase of a printing and dyeing industrial wastewater treatment plant (WWTP) in Wuxi, Jiangsu Province is 5.0×104 m3/d. The composition of the wastewater is complex, and the concentration of refractory organic matter is high. While the requirements of effluent reuse rate and quality are high. The effluent quality is required to implement the level A in table 1 of Discharge Standard of Pollutant for Municipal Wastewater Treatment Plant (DB 32/4440-2022) in Jiangsu Province. Based on the characteristics of influent quality, the WWTP is designed into the high concentration and the low concentration wastewater treatment systems. The treatment process adopts pre-treatment, biochemical treatment, and advanced treatment units, and the effluent was reused in multi-level. In response to the tight land use, the processing technology was selected reasonably, the individual design was optimized, intensive and compact layout was adopted to reduce land occupation. The main design parameters of constructures were elaborated and the engineering investment and operating costs were also analyzed.
