High-salt complex wastewater reuse and zero discharge integrated equipment and technology

The invention relates to high-salt complex wastewater reuse and zero discharge integrated equipment and a technology. The equipment provided by the invention comprises a pretreatment system, a reuse and reduction system and a zero discharge system. The technology comprises the following steps: carrying out homogenization and averaged quantity on high-salt complex wastewater, successively adding sodium hydroxide, sodium carbonate, PAC and PAM to carry out coagulation treatment, letting a mixed liquor which has undergone coagulation treatment enter a filter tank for sedimentation and filtration by the use of an immersed microfiltration membrane, letting a supernatant enter a reverse osmosis treatment process, letting pure water obtained by reverse osmosis treatment enter a reuse water tank for utilization, further condensing condensed brine, and crystallizing the condensed brine or putting the condensed brine into an evaporation pond for atomization and evaporation processing, wherein the reverse osmosis treatment adopts three-level RO: a medium-pressure membrane element is firstly used for desalination and condensation; a high-pressure membrane element is then used for further desalination and condensation; and a ultrahigh-pressure membrane element is finally used for further desalination and condensation. According to the invention, 95% of reverse osmosis concentrated water or analogous high-salt complex wastewater can be recovered for reutilization, only 5% of high strong brine is left to undergo evaporative crystallization or enter the natural evaporation pond. Water resources are fully recycled, and reuse and zero discharge costs of high-salt complex wastewater are reduced.

Method for preparing microbial symbiotic fermented bread kvass beverage

The invention discloses a method for preparing a microbial symbiotic fermented bread kvass beverage, relates to the method for preparing fermented beverages, and solves the problems of sterilization and turbidity due to small accumulation of metabolite and incomplete fermentation in the conventional method for preparing the bread kvass beverage by inoculating lactic acid bacteria and yeast in a big tank for fermentation and then filling the obtained product. The method comprises the following steps of: fermenting water, hop liquid, bread fermentation culture solution and flour for three times; fermenting, baking, slicing and baking the fermented product again to obtain sliced bread; dipping the sliced bread in water to obtain bread extract; adding water, rice, high-temperature-resistant amylase and saccharifying enzyme into a saccharifying tank for saccharification to obtain rice saccharifying liquid; fermenting the bread extract, the rice saccharifying liquid, solution of lactic acidbacteria and the bread fermentation culture solution twice; and filtering, filling and sterilizing the obtained product to obtain the beverage, wherein the total acidity of the beverage is 6.4 to 6.8DEG T, the total ester content is 0.05 to 0.06 percent and the beverage is clear. The method can be used for preparing the kvass beverage.

Wet-type ammonia flue gas spiritualization technics of associated desulfuration demercuration

The invention relates to a wet ammonia flue gas purification process for the combined sulfur and mercury removing and the system thereof. The process adopts chlorine gas as oxidizing agent to completely oxidize elemental mercury in the flue gas, and gas phase divalent mercuric ion after being oxidized is converted into liquid phase divalent mercuric ion through the improved wet ammonia desulphurization process, and further the liquid phase divalent mercuric ion is converted into stable mercuric sulfide sendimentation through liquid phase divalent mercuric ion stabilizing agent. The system comprises a flue gas oxidizing demercuration preprocessing system composed of an oxidizing agent injection device and an electrostatic precipitator, a wet ammonia flue gas sulfur and mercury removing system composed of a reaction absorbing tower, a sulfur removing accessory substance processing system composed of a cyclone cleaner, a dewaterer, and a dryer, and a mercuric sulfide HgS sendimentation processing system composed of a wastewater buffer pool, a liquid phase mercuric ion reaction chamber, and a settling pond. The process and the system can effectively improve the oxidation rate of the elemental mercury in the flue gas, overcome the defaults that the divalent mercuric ion is easy to be reduced and released and the secondary pollution problem is caused by excess oxidizing agent, and greatly improve the efficiency of sulfur removing and mercury removing.

Magnetic toner

Provided is a magnetic toner in which enhancement of initial transfer efficiency and transfer efficiency that is stable during a long-term use are achieved by simultaneously suppressing the friction force between the toner and a drum and the cohesion between toners, and further the degradation in chargeability and fluidity caused by the deterioration of the toner. The magnetic toner includes: a magnetic toner particle; a first external additive; and a second external additive. The first external additive includes an organic-inorganic composite fine particle, a plurality of convexes derived from an inorganic fine particle being present on a surface of the organic-inorganic composite fine particle, and has a number-average particle diameter of 50 nm or more and 500 nm or less. The second external additive includes a silica fine particle and has a number-average particle diameter of 5 nm or more and 30 nm or less. A shear load calculated from a rotation torque is 0.50 kPa or more and 2.00 kPa or less when a disc-shaped disc is pressed against a surface of a magnetic toner powder layer, the magnetic toner powder layer being produced by applying a vertical load of 9.0 kPa to the magnetic toner, under a vertical load of 5.0 kPa, and the disc which is being pressed is rotated, and an absolute value |ζ(T)−ζ(A1)| of a difference between a zeta potential ζ(T) of the magnetic toner particle dispersed in water and a zeta potential ζ(A1) of the first external additive dispersed in water is 50 mV or less.
