3results about How to "Guaranteed water purification effect" patented technology

The invention discloses an algae control ecological enclosure, a river and lake bank algae control system, a river and lake bank algae control and removal method, a reservoir water intake algae control system and a reservoir water intake algae control and removal method, and relates to the technical field of water environment treatment. The face, facing the water flow direction, of the flexible enclosure body is an intercepting face, the near-shore end of the flexible enclosure body is bent to form a fixing part, a fixing piece used for fixing the flexible enclosure body is arranged on the fixing part, and the flexible enclosure body is made of waterproof materials. The river and lake bank algae control system and the reservoir water intake algae control system comprise a plurality of algae control ecological enclosures. The device can intercept and gather algae on the water surface and the upper layer of the water body in the flowing water body to achieve the purpose of centralized control and centralized removal of the algae on the water surface and the upper layer of the water body, meanwhile, the algae on the lower layer of the water body can still freely flow, and a proper number of algae are kept to maintain the algae water purification effect.

The utility model discloses a circulating type industrial sewage treatment device, which relates to the technical field of industrial sewage treatment and comprises a hopper and a stirring barrel, a support I and a filter cartridge are arranged in the stirring barrel, the support I is cross-shaped, the stirring barrel is provided with a slag outlet, two ends of the filter cartridge are fixedly connected with the support I and the hopper respectively, the filter cartridge is communicated with the slag outlet, and the hopper is provided with a slag outlet. A screw is rotatably arranged in the filter cartridge, the two ends of the screw are rotatably connected with the hopper and the first support respectively, and a water inlet pipe is fixedly arranged at the lower end of the stirring barrel. When the circulating industrial sewage treatment device is used for treating sewage, the sewage is firstly poured into the hopper and enters the filter cartridge, so that the sewage and water-insoluble impurities can be filtered, then under the action of the screw rod, the impurities in the filter cartridge are extruded out of the filter cartridge, and the sewage enters the box body below through the water inlet pipe to wait for further treatment; the graded filtering treatment not only can ensure the filtering effect, but also can reduce the workload of each stage of filtering device.

The application relates to the technical field of fluid purification, and provides a water purification assembly of a household appliance, a control method of the water purification assembly and the household appliance. The water purification assembly comprises an electrodialysis membrane stack arranged on a water channel of the water purification assembly; a first sterilization component arranged upstream of the electrodialysis membrane stack; and a second sterilization component arranged on a soft water channel downstream of the electrodialysis membrane stack. The water purification assembly provided in the application can improve the bacteriostatic effect.
