This invention relates to the field of water pollution purification, specifically to a process for purifying and recycling industrial wastewater. The process provided by this invention induces the in-situ crystallization and precipitation of calcium and magnesium ions, primarily in the form of aragonite-type calcium carbonate, by adding a crystal form regulator to the wastewater. This replaces the traditional precipitation method using precipitants, fundamentally preventing the generation of secondary sludge. Simultaneously, a quencher regulates the type and concentration of active free radicals within the system, achieving targeted degradation of organic matter while maximizing the retention of beneficial ions in the water, ensuring the corrosion inhibition performance of the recycled water. This invention features a simple operation, requires no mechanical structural modifications, and can be directly adapted to existing industrial water treatment systems. It effectively solves the problem of simultaneously addressing hardness removal and organic matter degradation in circulating water wastewater treatment, significantly improving the purification and recycling efficiency of wastewater. The treated effluent can be directly reused in industrial circulating water systems.

The invention discloses a honeycomb biological carrier and a manufacturing method thereof, and relates to the technical field of sewage treatment. Comprising a supporting frame, at least one layer of honeycomb structure, a spiral outer rib and a coating, wherein a treatment space is formed in the supporting frame in a surrounding manner; the honeycomb structure is connected with the supporting frame and is arranged in the treatment space; the spiral outer rib is arranged between the honeycomb structure and the supporting frame, and the surface of the supporting frame, the surface of the honeycomb structure and the surface of the spiral outer rib are coated with the coating; the spiral outer ribs are used for increasing spiral disturbance of water flow, by arranging the spiral outer ribs, original linear or disordered motion of the water flow can be forcibly converted into rotary motion guided by the outer contours of the spiral outer ribs, and a retained water film on the surface of a carrier can be effectively damaged; and the substance exchange between the sewage and the surface of the biological membrane is changed from diffusion to convection, so that sludge and impurities are prevented from being deposited in pore channels.

The invention provides a high-water-retention-rate water-absorbent resin and a preparation method thereof. Aiming at the problems of poor water retention performance and the like of the traditional water-absorbent resin, in a polyacrylic acid-acrylamide and polyvinyl alcohol double-network system, a hyperbranched polysiloxane prepolymer and a traditional cross-linking agent are compounded for use to jointly prepare the high-water-retention-rate interpenetrating network water-absorbent resin, and the high-water-retention-rate interpenetrating network water-absorbent resin can be practically applied to the fields of agricultural water-retaining agents, industrial slow-release materials and the like.

The invention discloses an aeration control method and device for sewage treatment, equipment, a storage medium and a program product, and relates to the technical field of sewage treatment.The aeration control method for sewage treatment comprises the steps that modal decomposition is conducted on water quality sequence data, and a multi-layer modal sequence of the water quality sequence data is obtained; determining correlation characteristics based on the multilayer modal sequence and the aeration index; screening out a target model index from the aeration indexes according to the correlation characteristics; and constructing an aeration control model based on the target model index. Due to the fact that the fluctuation interference problem in the original water quality data is solved through modal decomposition, the influence of noise on aeration control is reduced, and the accuracy of aeration control is improved. Through correlation mapping, only key indexes in the water quality data are reserved, light-weight control of sewage treatment is achieved, and system resources needed by aeration control are reduced.

The utility model relates to the technical field of coast breakwaters, and discloses an arc-shaped breakwater group arrangement structure which comprises a plurality of first breakwaters and a plurality of second breakwaters, and a plurality of wave absorbing grooves are formed in the outer walls of the front ends of the first breakwaters at intervals. And permeable waterproof agents are arranged on the outer walls of the front ends and the outer walls of the rear ends of the first breakwater and the second breakwater correspondingly, and corrosion-resistant layers are arranged on the sides, away from the first breakwater and the second breakwater, of the permeable waterproof agents correspondingly. The arc-shaped structure guides a wave propagation path, promotes wave energy to be dissipated step by step and achieves efficient wave dissipation, in terms of ecological friendliness, water exchange channels are specially reserved in the layout, natural water power circulation of a sea area is maintained, and the problems of water quality deterioration, biological inhabitation environment damage and the like caused by water flow blocking are solved. By means of the design, wave dissipation is achieved, meanwhile, smoothness of water exchange is guaranteed, a stable living space is created for marine organisms, and the characteristic of being friendly to the ecological environment is highlighted.

The implant delivery funnel may include a funnel body, a funnel opening, and a funnel outlet, the funnel opening and outlet being located at opposite ends of the funnel body. The funnel body may include an outer base layer and an inner coating layer fixed to the functionalized mating surface of the outer base layer. The inner coating layer may be hydrophilic, forming a lubricating coating with retained water. The funnel opening is sized to receive the implant through the opening without the implant becoming permanently deformed. The funnel outlet has an adjustable size to compress and deliver the implant through the outlet while temporarily reducing its size.
