energy-saving integrated facility for seawater desalination in island has been built in the DongTou Da Qu Island.
The facility used advanced technology such as reverse osmosis, energy recovery, micro-electrolysis, electronic antibacterial to obtain excellent water
quality, low energy consumption, low cost and covers less area. The facility's demonstration breaks the monopoly of desalination energy recycling
facilities of foreign companies.
It is important to reduce the cost of seawater desalination project ,the energy consumption and the cost of the
equipments. It is also important to improve develop the water quality. It is better to alleviate water crisis of Chinese islands and some coastal villages. It
has great significance to insure the safety of supplying fresh water of Chinese desalination

Abstract :
Mine water pollution is serious. Drainage of this kind of water directly outside the row will take a threat to the mining area and the surround-
ing ecological environment. Taking the Xingwang coal mine as an example, the specific process of governance of the mining water, demonstrated the
feasibility of wastewater disposal technology, as well as mine water treatment costs were analyzed. The process can be effective in removing sewage
COD, SS, Fe. The treatment results meet the recycle and emission standards and the running costs were low.

Abstract:
According to the wastewater quality, a process of anaerobic fluid blanket -contact oxidation was used to treat wool textile and dyeing
wastewater. The results of the operation showed that the removal rate of COD, BOD
5
and color were 95%, 96% and 93%, respectively, when the COD,
BOD
5
, color of the inlet water were 1 700 mg·L
-1
, 450 mg·L

and 300. The effluent quality can come up to first-class criteria specified in the Effluent
standards of pollutants for dyeing and finishing of textile industry (GB4287-1992). The operating cost was about 0.54~0.84 yuan·m
