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 relates to a blank supplying and automatic bottle shedding mechanism of a plastic blowing machine, which comprises a stander, a template, a die, a die opening and closing mechanism and a blowing mechanism, wherein the template, the die and the die opening and closing mechanism are arranged on the stander. The blank supplying and automatic bottle shedding mechanism of the plastic blowing machine is characterized in that a blank supplying device and an automatic bottle shedding mechanism are arranged on the die, the blank supplying device comprises a supporting plate which is arranged on the stander or the die, a plastic bottle blank guide cylinder is arranged in the supporting plate, the center of the guide cylinder is in the same straight line as the center of the die, and ablank receiving fork is arranged on a die orifice of the movable die and contacted with a plastic bottle blank; the automatic bottle shedding mechanism comprises a bottle mouth extruding device and abottom die rotating device, the bottle mouth extruding device comprises a pushing plate and a spring which are fixed on the die orifice of the fixing die, and a post rod is arranged on the movable die and matched with the pushing plate; and the bottom die rotating device comprises a rotating shaft which is connected in series with bottom dies, the head of the rotating shaft is provided with a pulling block which is contacted with a contact rod arranged on the stander or the die to rotate, and the rotating shaft is provided with a resetting spring.

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.
