Dual-System Solution for Urban Water Cycle Governance

Shanghai Shangzi Engineering Design Co., Ltd. is a design entity under MSW, specializing in water pollution control, water resource purification, ecological restoration and other related fields. As a national high-tech enterprise, it boasts comprehensive service capabilities covering planning, design and consulting throughout the entire process

1、Urban domestic sewage treatment

For domestic sewage from residents, the combined process of "pretreatment + biochemical treatment + advanced treatment" is adopted to efficiently remove pollutants, with the effluent meeting the first-class standard.

Through physical separation, microbial degradation and chemical purification, it can efficiently remove pollutants such as COD (Chemical Oxygen Demand), BOD (Biochemical Oxygen Demand), ammonia nitrogen and total phosphorus in sewage, while reducing the content of suspended solids and pathogens.

The modular design is suitable for scenarios of different scales, with a treatment efficiency of over 90%.

2、wetland park reclaimed water treatment system

Taking the tail water of sewage treatment plants as raw water, it integrates the ecological treatment technologies of "constructed wetland purification + aquatic plant absorption + microbial transformation". After 格栅拦截 (grille interception) and sedimentation tank pretreatment, it utilizes the adsorption and filtration of wetland substrates (soil, sand and gravel), the absorption and enrichment functions of submerged plants (such as Vallisneria natans and Hydrilla verticillata), as well as the degradation of microorganisms to deeply remove pollutants such as nitrogen, phosphorus and trace organic matter. It deeply purifies water quality and simultaneously constructs a composite system of "water treatment + ecological restoration + landscape", contributing to the construction of low-carbon cities.
