ABSTRACT
Reclaimed water is called renewable water, recycled water, or reuse water. It mainly refers to the city waste water which achieves certain water quality standards after being treated; also the non-potable water that can be reused within the certain limits, and the water quality is between supply water to sewerage. The reclaimed water reusing can not only recycle water resources to create economic benefit well, but also bring the corresponding environmental benefits. BFBS is a typical compound system, which has high density microbes, high load capacity, good condition on mass transfer, high reaction rate, high impact load ability, etc. It is a useful exploration to apply BFBS to deal with municipal wasterwater which can improve efficiency highly and reduce processing cost.
