5results about How to "Avoid water quality deterioration" patented technology

This utility model provides a crab and bass polyculture device, relating to the field of aquaculture technology. It includes a pumping device, an outer box, and an inner box coaxially arranged with a clearance fit. Two limiting grooves are formed inside the inner box. A water pump is fixedly connected inside the inner box, and rotary joints are connected to both ends of the water pump. The other end of each rotary joint is connected to a circular box slidably connected to the limiting grooves. A motor drives a synchronous pulley and a synchronous belt to drive the circular box to slide within the limiting grooves, allowing the water inlets on the circular box to connect with water pipes in different directions. Combined with the power of the water pump, this enables bidirectional water flow between the two ponds, constructing a bidirectional water exchange system between the crab and bass ponds. This improves water resource utilization, prevents water quality deterioration in a single pond, promotes the sharing of beneficial substances between the two ponds, and reduces aquaculture costs.

This utility model provides a high-efficiency and energy-saving integrated tank-pump pressure-stabilizing water tank, relating to the field of water supply equipment processing technology. It includes an integrated tank-pump pressure-stabilizing water tank assembly, with a filter component on its side, and reinforcing and buffer components on its top. The assembly comprises a water tank and an energy-saving pressure-stabilizing pump. In this utility model, multiple filter elements are installed inside the filter box, which effectively filters the water source, removing impurities and particulate matter to prevent them from accumulating inside the tank. The activated carbon box further adsorbs microorganisms in the water source, further purifying the water quality, reducing corrosion and wear of the tank, extending the service life of the integrated tank-pump pressure-stabilizing water tank assembly, and maintaining the cleanliness of the water inside the tank, preventing water quality deterioration due to bacterial growth caused by impurities.

The application discloses a photoelectric coupling device and treatment method for continuously disinfecting and purifying swimming pool water, and belongs to the technical field of swimming pool water treatment. The device comprises an electrochemical treatment unit and an ultraviolet treatment unit which are sequentially connected. The electrochemical treatment unit is provided with a filter assembly, a water pump and an in-situ E-peroxone reactor, and an integrated coaxial electrode is arranged in the reactor. The ultraviolet treatment unit is provided with an ultraviolet reactor with a VUV / UVC light source. The swimming pool circulating water is first subjected to electrochemical treatment and then subjected to ultraviolet treatment to form a synergistic oxidation system. Preferably, the residence time of the electrochemical unit is 5-10 min, the residence time of the ultraviolet unit is 10-15 min, the current density is 10-200 mA / cm 2 , and the ultraviolet dose is 200-1000 mJ / cm 2 . The device is suitable for continuous flow treatment of swimming pool water with a chlorine ion concentration of 200-2000 mg / L, containing urea, creatinine and / or hippuric acid.

The utility model discloses a kind of aquaculture pond sewage discharge devices, it is related to pond sewage discharge technical field, including aquaculture pond, the left end of aquaculture pond is connected and is installed with filter device, the lower end of aquaculture pond left side is fixedly installed with sewage collection device.The utility model said a kind of aquaculture pond sewage discharge device, by setting pond bottom and sewage collection device, water flow is flowed to left side through the top of pond bottom, and then make sludge slowly slide to the inside of mud collection foundation pit, by the circulation flow of water, and then facilitate to collect sludge;By setting filter device and sewage collection device, realize the staged filtration to dirt, improve the sewage efficiency of aquaculture pond;By the action of fixed button and float, the water level inside the water tank connected is detected, sludge pump is extracted to the inside of sewage collection tank through sludge extraction pipe and sludge discharge pipe to the sludge in the inside of mud collection foundation pit, so that sewage collection tank collects sludge, realizes the automatic cleaning of sludge, avoids the deterioration of water quality in aquaculture pond.
