The invention relates to a filtering device comprising a casing, wherein a water inlet and a water outlet are formed on the top and the bottom of the casing respectively; a double-layer filter plate is arranged on the inner wall of the casing and is provided with mesh holes; filtering media are arranged between the double-layer filter plate; a filter cloth is arranged at the water inlet; a filter element is arranged on the lower part of the double-layer filter plate; the lower part of the filter element is conic; and the filter element is communicated with the water outlet. The filter media and the filtering element of the filtering device have high pollutant absorbing capability, high filtering speed, good purification effect, safety and reliability, zero pollution, and a long service life, meanwhile, residues can be sucked away by a suction pump and a suction pipe so as to prevent the filter cloth from blockage.

The invention discloses a sewage suction device for a filter used in agricultural irrigation, which mainly includes a sewage suction pipe and a plurality of high-pressure suction nozzles, and the multiple high-pressure suction nozzles are evenly fixed on the outer wall of the sewage suction pipe and communicated with the sewage suction pipe , the plurality of high-pressure suction nozzles are all provided with high-pressure nozzles inside, and the high-pressure nozzles can spray high-pressure water flow. The high-pressure nozzle is concentric with the high-pressure suction nozzle, and a high-pressure pipe concentric with the sewage suction pipe is arranged inside the sewage suction pipe. The high-pressure nozzles are all communicated with the high-pressure pipe, and the high-pressure pipe can obtain high-pressure water flow from a high-pressure pump. In the present invention, high-pressure nozzles concentric and coaxial with the high-pressure suction nozzles of the original sewage suction device are provided. High-pressure water flow can be sprayed from the high-pressure nozzles to spray the inside of the fine filter screen, so that both sides of the filter screen can be thoroughly cleaned. The moment the fouling is washed away by the high-pressure nozzle, the suction nozzle will suck. After such improvement, it can realize spraying and suction at the same time, so that the dirt suction capacity is obviously improved.

A multi-purpose indoor wiping tool, including a wiping tool and a wiping cloth processing device, characterized in that: the wiping tool is composed of a pressing plate (2), a cloth connecting device and a wiping cloth (4); the pressing plate is a rectangular plate The wiping cloth is a rectangular piece of cloth; only one side of the wiping cloth is connected with the cloth connecting device, and the cloth connecting device is installed on the pressing plate; the pressing plate is provided with a handle; the wiping cloth The processing device consists of a net stripper and a base 7 on which the net stripper is installed. The multi-purpose indoor wiping tool of the present invention has simple structure, convenient operation and wide application, and can help people quickly and efficiently wipe the surfaces of various indoor objects without dirty or damaging hands, thus having strong practicability.

The invention discloses an undercurrent artificial wetland plant breeding and domesticating method, and relates to biological treatment of water, wastewater or sewage. The undercurrent artificial wetland plant breeding and domesticating method comprises the following steps: by a dry-wet alternate seedling domestication method, through primary domestication, with 14 days as a period, gradually increasing a hydraulic load and an organic load to screen out seedlings with the heights of 1.8-2.0 m; performing secondary domestication to obtain wetland plants with high stress resistance, strong pollution absorbing capacity, a developed root system and dense stems and leaves. By the undercurrent artificial wetland plant breeding and domesticating method, the treatment capacity of a wetland is increased by 10-20%; intergenerational transmission can be performed on the seedlings with a certain genetic property, which are bred and domesticated for a long time.

A two-stage filtering self-cleaning filter adopting internal and external filter cylinders comprises a seal casing constituting a filter cavity, a pollution absorption pipe and a driving device, wherein a first-stage filter cylinder and a second-stage filter cylinder are arranged in the casing, a water inlet communicates with an inner cavity of the first-stage filter cylinder, water enters an outer cavity of the first-stage filter cylinder through the inner cavity of the first-stage filter cylinder to realize first-stage filtration, the first-stage filter cylinder is covered with the second-stage filter cylinder, the outer cavity of the first-stage filter cylinder is divided into an inner cavity of the second-stage filter cylinder and an outer cavity of the second-stage filter cylinder by the outer cavity of the first-stage filter cylinder, and water enters the outer cavity of the second-stage filter cylinder through the inner cavity of the second-stage filter cylinder to realize second-stage filtration. According to the two-stage filtering self-cleaning filter adopting the internal and external filter cylinders, the internal space utilization rate of the filter is effectively increased, and the maintenance space of the filter is reduced. With the adoption of the internal and external dual-filter-cylinder layout design, the first-stage filter cylinder is arranged in the second-stage filter cylinder, only the length space of the second-stage filter cylinder is required, so that the height of the filter is reduced, and then the maintenance space of the device is reduced effectively.
