The features and treatment process of coal contained wastewater in thermal power plants have been presented,a highly effective clarifier being used in the treatment system of coal contained wastewater in Wenzhou Power Plant.

To improve the non-biology-stability of navel orange dry wine,the clarification effects of 5 different quantities clarificants of agar,glutin,diatomite,benotonite and chitosan on navel orange dry wine were compared at zero to 2,40 to 45 centigrade degree and normal temperature,respectively.

This paper compared the clarification effect and physical-chemical compositions of mulberry juice,and the results showed it produced better clarification result to use 700 mg/L Bentonite,160 mg/L Pectinase,200 mg/L Casein,50 mg/L PVPP singly at 3-5 ℃ for 18 hours.

The result of the experiment showed that chitosan had the best clarification effect on litchi juice, and its optimum concentration for the most rapid flocculation settlement of litchi juice was 0.

By way of improve the actuality of sulphitation process's low lustration efficiency, this research will discuss the clarification result of producing saccharate replace milk of lime as clarifier by the third mill's extracted juice.
