This invention discloses a resource recovery system for dredged sediment treatment based on ultrasonic extraction and flotation synergy, comprising: a pretreatment unit, a first-stage ultrasonic extraction reaction unit, a second-stage solid-phase adsorption reaction unit, a third-stage flotation separation unit, a dewatering unit, a residual water treatment unit, and a nitrogen and phosphorus recovery unit. It also discloses a resource recovery method for dredged sediment treatment based on ultrasonic extraction and flotation synergy. This invention solves the problems of low pollutant removal rate, high risk of secondary pollution of dredged soil, and limited resource recovery in traditional dredged sediment treatment. Through the synergistic effect of multiple units including "ultrasonic-liquid-solid-phase adsorption-micro-nano bubble flotation," it achieves efficient release of nitrogen and phosphorus, simultaneous removal of microplastics, rapid separation of clean sediment from polluted phases, and recovery of nitrogen and phosphorus for fertilizer production and resource recovery of clean sediment. The entire process is green and low-consumption, suitable for compact layout on water or near shore, and can simultaneously meet the requirements of sediment reduction, harmlessness, and resource recovery.

This invention relates to the field of beer production technology and discloses a mixing device and process for beer production. The device includes a tank with an upper water pipe and a lower liquid pipe at its upper and lower ends, respectively. The side wall of the tank has inlet and outlet ports. An internal filter screen is installed inside the tank. The tank also contains a stirring shaft, a rotating ring, a vertical rod, an anchor-shaped paddle, and a tillering paddle. The stirring shaft is rotatably mounted inside the tank. This mixing device, through the arrangement of the stirring shaft, rotating ring, vertical rod, anchor-shaped paddle, and tillering paddle, and in conjunction with a lifting control mechanism, achieves synchronous reverse lifting and lowering movements of the anchor-shaped paddle and the tillering paddle. This eliminates the need to transfer the mash and malt between the mashing tank and the filter tank, thus completing the integrated mashing and malt washing process. This effectively shortens the production process, reduces equipment footprint, avoids heat loss and material residue during wort transfer, improves raw material utilization and production efficiency, reduces the risk of microbial contamination, and ultimately ensures the quality of the produced beer.

This invention discloses a deep defluorination device and its defluorination process for wastewater, relating to the field of defluorination equipment. It includes a resin column with an inner temperature-regulating column coaxially arranged inside and an outer temperature-regulating column coaxially arranged on its outer wall. The inlet of the outer temperature-regulating column is located at its top, and its outlet is located at its bottom. The inlet and outlet of the inner temperature-regulating column are opposite to those of the outer temperature-regulating column. A spiral tube is located inside the outer temperature-regulating column, with its top end connected to both an air inlet pipe and a regeneration liquid inlet pipe located outside the resin column. The bottom end of the spiral tube is connected to a cleaning water inlet pipe located outside the resin column. This invention utilizes flowing temperature-regulating water to transfer heat through the side walls of the resin column and the inner temperature-regulating column, rapidly achieving indirect temperature regulation of the liquid inside the resin column during both the adsorption and regeneration phases, thus balancing the adsorption efficiency and capacity during the adsorption phase.

The application provides a method for preparing fish skin collagen peptides with high antioxidant activity by DHPM and UIO-66 molecular imprinting, and relates to the technical fields of aquatic product deep processing and bioactive peptides. The method comprises the following steps: fish skin pretreatment, DHPM-induced collagen protein unfolding, endogenous enzyme autolysis, crude separation, selective target enrichment by using UIO-66 material with histidine as a molecular imprinting template, and drying collection. The application destroys the dense triple helix structure of collagen protein by using the physical field effect of dynamic high pressure microfluidization, exposes the enzyme cutting site, uses the endogenous enzyme of fish skin for autolysis, and then uses the histidine molecular imprinting UIO-66 material to accurately capture the high antioxidant activity peptide segment, so that the enzymolysis efficiency and the antioxidant activity of the product are significantly improved. The application does not need to add exogenous enzymes, and has the advantages of green process, low cost and high product purity. The obtained fish skin collagen peptides can be widely applied to the fields of functional food, cosmetics and medicine.
