This application discloses an integrated cleaning device, relating to the field of cleaning equipment, comprising a frame; a loading rack installed at one end of the frame; a unloading rack installed at the other end of the frame; a transfer mechanism installed on the frame and used for transferring optical components; a hydrocarbon cleaning unit installed on the frame and adjacent to the loading rack, the hydrocarbon cleaning unit being used to clean optical components using hydrocarbon solvents; and an HFE cleaning unit installed on the frame and adjacent to the unloading rack. This application reduces the footprint by integrating the hydrocarbon cleaning unit and the HFE cleaning unit onto the frame; it reduces mutual interference and improves safety by physically isolating the hydrocarbon cleaning unit and the HFE cleaning unit with partitions; and it prevents large amounts of hydrocarbon solvent from entering the next process by using air knife purging, greatly reducing the contamination load of subsequent HFE solvents and minimizing cross-contamination.

This application discloses a seaweed oligopeptide fertilizer for promoting root growth and seedling development, and its production process, belonging to the field of fertilizer technology. The fertilizer, by weight, comprises: 2-10 parts seaweed oligopeptide complex, 1-8 parts seaweed extract, 10-30 parts compound amino acids, 1-10 parts blueberry pomace, 20-50 parts oxytetracycline waste decomposition products, and 30-60 parts recycled organic matter from kitchen waste. By combining seaweed oligopeptides with chitosan to form a complex, the stability of the active ingredients is improved; simultaneously, the synergistic utilization of oxytetracycline fermentation waste, kitchen waste, and blueberry pomace achieves resource utilization. Experiments show that this fertilizer significantly promotes crop root growth and seedling development.

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.

The invention relates to the technical field of sewage treatment, and discloses a method for treating chicken raising wastewater based on coupling of ultrasonic ozone and a sulfur autotrophic fungicide, which comprises the following steps: (1) performing ultrasonic-ozone combined pretreatment on the chicken raising wastewater; and (2) treating the effluent in an anaerobic reaction system containing a compound microbial agent and a sulfur-containing filler. According to the method, dephosphorization and wall breaking are enhanced through ultrasonic ozone, ammonia nitrogen is directly converted into nitrogen through the synergistic effect of the specially-made filler and the functional bacteria under the anaerobic condition, efficient nitrogen and phosphorus removal is achieved, the process is simplified, and operation is stable.

The application provides a modular aquatic higher plant ecological treatment method and system for sea urchin / sea cucumber breeding tail water, and belongs to the technical field of breeding tail water treatment. The application adopts a tail water introduction-primary rough filtration-secondary ecological purification-tertiary deep purification gradient process, and the treated tail water is divided into two streams, one of which is used for breeding ponds and the other is discharged up to the standard. The application does not add chemical agents, realizes residue bait reuse and tail water circulation, is stable, efficient, low in cost, easy to maintain, suitable for large-scale breeding, and can directly reuse the treated tail water after disinfection, greatly saves seawater resources, forms a complete breeding water circulation closed loop, and has the advantages of ecology, practicability and economy, and is suitable for tail water treatment and resource utilization of various sea urchin / sea cucumber breeding modes.
