5results about How to "Improve the efficiency of solid-liquid separation" patented technology

This invention provides a method for producing single-cell protein using a mixed bacterial culture, comprising the following steps: performing primary seed culture on methanogenic bacteria, *Tricholoma materata*, and *Glucosinolate methyl-eating bacteria* to obtain primary seed solutions; mixing the primary seed culture solutions evenly to obtain a mixed bacterial solution; inoculating the obtained mixed bacterial solution into a secondary seed culture medium for cultivation to obtain a secondary seed solution; inoculating the obtained secondary seed solution into a fermentation medium for scale-up cultivation to obtain a fermentation broth; separating the solid and liquid components of the obtained fermentation broth, harvesting the bacterial cells, and obtaining single-cell protein. This method for producing single-cell protein using a mixed bacterial culture improves the utilization rate of the carbon source methane and the yield of single-cell protein.

The utility model relates to the technical field of cheese production discloses a liquid separation device for cheese production, include: conveying separation cylinder, its top is equipped with feed inlet, bottom is equipped with solid -liquid separation net and base, driving mechanism, including fixed in conveying separation cylinder top's drive motor and the conveying shaft of penetrating cylinder body, spiral conveying subassembly, including install on the small interval spiral vane of conveying shaft, middle distance spiral vane and big interval spiral vane, three groups of spiral vane follow the solid -liquid separation net from feed inlet along material conveying direction and set gradually. The spiral conveying subassembly that sets up realizes the effective extrusion and the delivery of cheese raw materials through the spiral vane design of different interval, improved the efficiency that solid -liquid separated. Small interval spiral vane carries out close extrusion to raw materials in initial stage, is helpful to discharge the superfluous liquid among it, and gradually increasing spiral vane interval provides more relaxed delivery environment in the subsequent process, avoids the solid component damage caused by excessive extrusion.

This invention discloses a humic acid-based water pollution treatment device, comprising a treatment tank and a sludge extraction and aeration device. The treatment tank contains a filtration mechanism and a humic acid adsorption mechanism arranged sequentially along the water flow direction. The humic acid adsorption mechanism includes a support plate horizontally installed inside the treatment tank and several humic acid balls placed above the support plate within the treatment tank. The support plate has several through holes, and the humic acid balls accumulate on the support plate to form an adsorption medium layer. The top of the support plate has several pressure relief holes, which are unidirectionally connected to the exhaust end of the sludge extraction and aeration device. The filtration mechanism includes an annular collection tank, a conical filter plate, and a floating shielding assembly. The annular collection tank is coaxially fixed to the inner wall of the treatment tank. This invention effectively solves the problems of easy caking of filter media, low cleaning efficiency, incomplete pollutant adsorption, and high energy consumption in traditional wastewater treatment equipment, achieving highly efficient wastewater purification.

The utility model relates to centrifuge technical field, the utility model provides horizontal vibration centrifuge, including the casing, having the side opening in one end of casing, the bottom has the discharge gate, the door body for plugging the side opening is hinged on the casing, the sieve basket subassembly rotation is arranged in the casing, is used for screening material, the scraper assembly is connected in the casing, and extends to the sieve basket subassembly, the scraper assembly can scrape the material adhered on the sieve basket subassembly when the sieve basket subassembly rotates, the scraper assembly has the gas outlet, the gas outlet is used for to sieve basket subassembly spouts gas to remove the material in the sieve slit of sieve basket subassembly. Through the above technical scheme, the material adhered on the sieve basket subassembly and the material in the sieve slit can be effectively removed. Reduce the material accumulation on the sieve basket subassembly, improve the screening efficiency and processing capacity of horizontal vibration centrifuge, avoid the low dehydration efficiency problem caused by the poor screen surface cleaning.

The application discloses a method for treating pathogenic bacteria in reclaimed water by using biochar-microalgae biofilm particles, which comprises the following steps: culturing chlorella, preparing biochar-microalgae biofilm particles, and adsorbing. The biochar-microalgae biofilm particles can effectively fix the microalgae and prevent the microalgae from flowing out of the reactor. After the treatment is completed, the microalgae can be easily separated from the wastewater, and the separation cost is low. The microalgae has high activity and strong secretion of extracellular excretion, and the overall treatment efficiency is high.
