Recently, at the Hejiayan Wastewater Treatment Plant in Wanzhou District, staff were observed carrying out daily operational tasks. The plant began trial operations in September, with personnel conducting dissolved oxygen testing, pH level testing, and SV30 observations to monitor sludge settling performance, ensuring smooth and orderly trial operations.


The Hejiayan Wastewater Treatment Plant is expected to have a daily treatment capacity of 30,000 cubic meters, addressing the wastewater treatment needs of nearly 200,000 residents in the high-speed rail area.
