This invention relates to the field of sterilization treatment device technology, and discloses a sterilization treatment device for dishwasher water, including a dishwasher and a sterilization lamp installed inside the dishwasher, and further including: a filter section installed on the dishwasher; a backflushing section installed on the filter section; a sterilization section installed on the dishwasher; the filter section includes an installation assembly installed on the dishwasher; a limiting assembly installed on the installation assembly; the installation assembly includes a conveying pipe connected to the dishwasher, and a support ring is provided on the inner wall of the conveying pipe. This invention, by setting up a filter section, solves the problems of existing sterilization treatment devices where the filter screen uses a fixed or entirely enclosed installation structure, mostly requiring auxiliary tools, making operation difficult, and making timely and convenient maintenance difficult after the filter screen becomes clogged. Long-term accumulation of debris can easily cause water circuit blockage, slow water flow, and easily lead to water backflow.

The invention discloses a silurus meridionalis ecological breeding method based on a land-based round pond and a rice field system, which comprises the following steps: firstly, building the rice field system and the land-based round pond, connecting the rice field system with the land-based round pond through a water body circulating system, and limiting a water body volume ratio; and then putting the small-sized primary fries into the land-based round pond, feeding the small-sized primary fries with feeds with different particle sizes for cultivation, screening out large-sized secondary fries from the land-based round pond after cultivation for 30-45 days, transferring the large-sized secondary fries to a rice field system, feeding the large-sized secondary fries with feeds with different particle sizes and natural baits, and continuing to cultivate the large-sized secondary fries until adult fishes are obtained. The land-based round pond, the rice field system and the water body circulation system are combined to form an ecological circulation culture system, the relation between the nitrogen and phosphorus bearing capacity of the rice field system per unit water body and the discharge concentration of the tail water of the round pond is accurately defined by setting the water body proportion of the rice field system and the land-based round pond, the pollutant load is balanced, and the yield of the round pond is improved. Therefore, the water quality purification efficiency is improved, the problem of large water quality fluctuation in a traditional mode is solved, and the ecological coupling efficiency is improved.

The invention discloses an assembly type composite artificial wetland system and method in the technical field of water treatment. The assembly type composite artificial wetland system comprises a main body frame, a subsurface flow wetland module, an upstream flow deep bed composite biological filter and an integrated process intelligent water distribution system, the main body frame comprises a supporting structure, a grating and a bottom supporting structure, and the grating divides the interior of the main body frame into an upper layer and a lower layer; the subsurface flow wetland module and the upstream flow deep bed composite biological filter are respectively arranged on the upper layer and the lower layer of the main body frame; the upstream deep-bed composite biological filter forms a multi-stage hierarchical structure along the water inlet direction; the integrated process intelligent water distribution system is located in the main body frame; the main body frame adopts a structural ecological design, and compared with a traditional concrete / reinforced concrete pool body structure, the energy consumption in the building construction process is lower; the treatment system adopts novel environment-friendly functional materials, and is suitable for ecological restoration of river / landscape water, upgrading and recycling of municipal tail water, recycling of aquaculture wastewater and treatment of agricultural non-point source pollution.
