Natural polymer,synthetic macromolecule and modified polymer were widely used in liquor-making industry.

In order to increase the output of bioflocculant,improve its efficiency and stability and enlarge its application scope,four yeast-like flocculant-producing strains were cultured in distillery wastewater and the optimum culture conditions were investigated.

The distillery wastewater was used as culture medium instead of traditional expensive culture medium to culture their mixed strains HXJ-1.

Turbidity easily occurs in blending liquor due to the change of solubility conditions of the solute.

Although the causations for precipitate in blending liquor are in many ways and the precipitate components are complicated, we can use different methods for the analysis of the relative precipitate components: Silico-tungsten acid method, Mayer method and Dragendorff method for the analysis of alcaloid; Ninhydrin method, Biuret Reation method etc.

Then after blending,flavoring,sterilization,storage and bottle filling,kiwi fruit liqueur was finally developed.

Application of two-stage bio-contact oxidation processto alcohol wastewater treatment;

Bacillus cereus,Pichia membranifaciens and mix-strains(named as HXJ-1) consisting of these two strains were used to produce bioflocculant by utilizing alcohol wastewater.

Contrast tests of direct sample injection approach(DSI), wine dilution sample injection approach (WDSL)and sample calcinations approach (SC)were done by the application of atomic absorption spectrophotometer to analyze manganese ion contents in imitation wine.

Raw materials and production techniques and production environments could pollute imitation wine, in order to improve its sanitary quality and prolong its shelf period, we have analyzed the examination results of the samples and found that it is necessary and feasible to formulate microbial indexes for imitation wine.
