The invention relates to a water-permeable brick for a water-permeable dam and the water-permeable dam. The water-permeable brick for the water-permeable dam comprises a brick body and an adsorption assembly which is arranged on the brick body and is used for adsorbing pollutants in a water body. According to the water permeable brick, the adsorption assembly is arranged in the brick body, pollutants contained in water penetrating through the brick body are adsorbed by the adsorption assembly, the content of the pollutants in the water penetrating through the water permeable brick is reduced, and therefore the water permeable brick has a high water quality purification effect. When the water-permeable bricks are laid on the water-permeable dam, the water-permeable bricks are used for covering the surface of the water-permeable dam, the water body is prevented from directly scouring the dam body of the water-permeable dam, and therefore the problem that the dam body structure is damaged due to water body scouring is solved through the water-permeable bricks. Due to the water permeable function of the water permeable bricks, the water permeable function of the water permeable dam is not affected, and the water permeable dam can have higher water quality purification capacity by utilizing the higher water quality purification capacity of the water permeable bricks, so that the water quality of a water body is improved, and the environment quality is improved.

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 a circulating water treatment method and system. The circulating water treatment method comprises the steps that water quality indexes are detected, and the water quality indexes comprise the pH value, the conductivity, the temperature, the chloride ion concentration, the sulfate radical concentration, the alkalinity, the hardness, the calcium ion concentration and the phosphate radical concentration; sending the water quality index to a water treatment system control terminal, and calculating the ion concentration; calculating equilibrium constants of water at different temperatures, and judging the scaling condition according to the ion concentration and the equilibrium constants; when scaling begins, the electric valve is opened, water enters the filtering system to be filtered, and then scaling ions in the water are removed through electrodialysis. According to the invention, the problems of large water consumption and difficulty in sewage treatment caused by scale formation through quantitative sewage discharge in the prior art are solved.
