Study on decolorizing method and mechanism in reclamation of black water;

Due to the more and more stringent requests for black water treatment and reuse, and the high-energy consumption of the traditional membrane bioreactor(MBR),a new hybrid membrane bioreactor with gravity outflow was developed.

In reclamation and reuse of black water, to lower the color of effluent is a difficult issue.

Study on seawater toilet-flushing sewage treatment by immobilized activated sludge;

on seawater toilet-flushing system were expounded.

Popularization of seawater toilet-flushing is one of the effective measures to solve the shortage of fresh water in coastal cities.

The emphasis of this paper was to investigate the COD and ammonia nitrogen removal rates of blackwater with treatment of recycling water flushing bio-toilet.

In view of the fact that the mass concentration of ammonia nitrogen in wastewater from toilet in tourism areas is high,the key factors that influence the improvement of the A/O biological denitrification process was selected by orthogonal experiment,the relativity between key factors and the removal rate of ammonia-nitrogen,as well as the optimal condition for the process were discussed.

Study was made on the treatment effect on seawater from toilet-flushing (simulation) by using phragmites communis, suaeda salsa, typha latifolia, and their combination.
