High Performance Wastewater Treatment Design Proposal - Nanchang City, China – JDL

Location: Nanchang City, China

Time: 2020

Treatment Capacity: 20,000 m³/d

WWTP Type: Facility Type FMBR WWTP

Project Brief:

In order to solve the environment issues caused by domestic sewage, and to effectively improve the quality of urban water environment, and at the same time, considering the disadvantages of traditional sewage treatment plants, such as large land occupation, heavy odor, need to stay away from the residential area and huge investment in pipe network, the local government chose JDL FMBR technology for the project, and adopted the concept of “Park aboveground, treatment facilities underground” to build a new ecological sewage treatment plant with a daily treatment capacity of 20,000 m³/d. The sewage treatment plant is built near the residential area and covers an area of only 6,667m². During the operation, there is basically no odor and the organic residual sludge is greatly reduced. The whole structure of the plant is hidden in the underground. On the ground, it is built into a modern Chinese garden, which also provides a harmonious ecological leisure place for the surrounding citizens.

FMBR technology is a sewage treatment technology independently developed by JDL.The FMBR is a biological wastewater treatment process that removes carbon,nitrogen and phosphorus simultaneously in a single reactor.Emissions effectively solve the “neighboring effect”. FMBR successfully activated the decentralized application mode, and is widely used in municipal sewage treatment, rural decentralized sewage treatment, watershed remediation, etc.

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.
