Process for treating high-concentration pyridine aqueous solution is carried out by boiling while distilling for high-concentration pyridine aqueous at constant temperature continuously, delivering itto top of tower to obtain pyridine-constant-hydrated boiling substances, circulation utilizing, hierarchical extracting 1-10 times with coarse pyridine biological diesel-oil as extracting solvent atnormal temperature, or countercurrent extracting continuously in proportion of solvent: waste water=5:1-1:10 and pH=4-10 for 3-30 mins, laying aside for 5-15 mins, separating, decompress distilling for extracting phase containing pyridine and biological diesel-oil, and recovering pyridine and biological diesel oil. It's simple, economical and has better effect and no environmental pollution.

The invention discloses a cationic dye dyeing wastewater decoloring agent as well as a preparation method and a use method thereof. The cationic dye dyeing wastewater decoloring agent is mainly prepared from black water-based ink printing waste liquid extracted sludge, pumice particles and calcium mineral powder, and the preparation method comprises the following steps: blending the black water-based ink printing waste liquid extracted sludge into a pulp state with a certain solid content, and adding an alkaline substance to neutralize the sludge to be neutral; adding a certain amount of the pumice particles and the calcium mineral powder into the sludge, and stirring uniformly; heating the sludge to 50-90 DEG C while stirring, and performing dehydration to enable the sludge to be blocky; squeezing and drying the blocky sludge; isolating the sludge from the air, heating to 350-750 DEG C, and keeping the temperature for 1-5h; cooling the sludge to a certain temperature, then crushing the sludge into particles, spraying a wetting agent solution, and then mixing uniformly; and adding a decoloring agent into cationic dye dyeing wastewater, stirring for 10-180min, performing filtration or air floatation to separate decoloring agent particles, and recovering the decoloring agent particles for recycling. With use of the prepared decoloring agent, the decoloring rate of the cationic dye dyeing wastewater is close to 100%, and the cationic dye dyeing wastewater can be reused.

The present invention relates to a method for separating and purifying lentinan, which is characterized in that after transforming the column type of the traditional chromatographic column to heterotype column, the lentinan coarse product is pretreated so as to ensure it to adopt the absorption of the heterotype column, the separating and purifying of the lentinan is changed to that of the lentinan dynamicly and high efficiently, thus to obtain single lentinan after a series of treatment of washing, elution, dialysis, deposition and freeze out etc. The advantage of the present invention is that it is suitable for producing large quantities and industrialisation, and can obtain high effect, low cost product with the precondition of method is simple as well as quality is good.

A spray-on plastic release agent, which is composed of A solution, B solution, C solution and D solution according to the volume ratio of 15~35:1.6:0.5:0.8~1; the A solution is prepared by the following method Preparation: get 100ml ethyl acetate, 15ml eucalyptus oil and 3ml glycerol carbonate and mix it; the B solution is made by mixing 100mL ethyl acetate and 15mL eucalyptus oil; the C solution is 10mL simethicone Prepared by dissolving in 100mL ethyl acetate; the D solution is a mixed surfactant solution prepared by dissolving 10g sodium stearate and 10g Tween-80 in 100mL water.
