Especially targeting the Southwest mountainous areas of China, a new anaerobic baffle reactor was designed for treating rural decentralized domestic wastewater. The reactor can be easily adjusted the proportion of the upper chamber and the down chamber to meet the variables of input water quality and quantity fluctuations not stabilized effluent technical bottlenecks, adapted to the multi-state variable flow to the different requirements..

1. Occupy little space. The reactor has a compact cylindrical structure.

2. Adapt to the variables of water quality and quantity.

3. Output water is used for agricultural irrigation.

Apply to the treatment of rural decentralized domestic wastewater in the mountainous areas.
