Nanchang City, China
Location: Nanchang City, China
Treatment Capacity: 10 WWTPs, the total treatment capacity is 116,500 m3/d
WWTP Type: Decentralized Integrated FMBR Equipment WWTPs
Process: Raw Wastewater→ Pretreatment→ FMBR→ Effluent
Due to the insufficient treatment capacity of the existing wastewater treatment plant, a large amount of wastewater overflowed into the Wusha River, causing a serious water pollution. In order to improve the situation in a short time, local government selected JDL FMBR technology and adopted the decentralized treatment idea of “Collect, Treat and Reuse the Wastewater On-sit”.
Ten decentralization wastewater treatment plants were set up around the Wusha River basin, and it just took only 2 months for one of the WWTP’s construction work. The project has a wide range of treatment points, however, thanks to FMBR’s characteristic of simple operation, it does not need professional staffs like the traditional wastewater treatment plant to stay on the site. Instead, it uses the Internet of Things + Cloud Platform Central Monitoring System and mobile O&M station to shorten the response time on site, so as to realize long-term and stable operation of wastewater facilities under the unattended conditions. The effluent of the project can meet the standard, and the main indexes meet the Water Reuse Standard. The effluent replenishes the Wusha river to make the river clean. At the same time, the plants were design to integrate the local landscape, realizing the harmonious coexistence of wastewater facilities and surrounding environment.
FMBR is the abbreviation for facultative membrane bioreactor. FMBR uses the characteristic microorganism to create a facultative environment and form a food chain, creatively achieving low organic sludge discharge and simultaneous degradation of pollutants. Due to the efficient separation effect of the membrane, the separation effect is far better than that of the traditional sedimentation tank, the treated effluent is extremely clear, and the suspended matter and turbidity are very low.
