WATER-POLLUTANT SEPARATION DEVICE, WATER-POLLUTANT SEPARATION AND FILTRATION DEVICE, ORNAMENTAL FISH TANK WATER-POLLUTANT SEPARATION AND FILTRATION SYSTEM, AND HIGH DENSITY CULTIVATION WATER-POLLUTANT SEPARATION, FILTRATION AND OXYGEN AERATION SYSTEM
Provided are a water-pollutant separation device, water-pollutant separation device based water-pollutant separation and filtration device, ornamental fish tank water-pollutant separation and filtration system, and high density cultivation water-pollutant separation, filtration and oxygen aeration system, comprising a tank, a water inlet pipe and a water outlet pipe respectively communicating with the top of the separation tank, and a pollutant discharge pipe disposed at the bottom of the tank the tank is provided with a separation structure in the inner cavity the separation structure is in an inverted barrel shape, has an upper closing cover and a profile slightly smaller than that of the tank, and provides a gap between the separation structure and the bottom of the tank a spoiler is installed on the water inlet pipe after the water inlet pipe passes through the upper closing cover of the separation structure in the tank the spoiler is sealed at the lower end, and is provided with a plurality of openings or slots on the side wall to generate a subcritical flow to spoil the water flow, the openings or slots being biased in the same direction. In the technical solution, a water-pollutant separation device is preferably added prior to fish tank filtration, and the multiple slots provided on the spoiler are suitable for splitting the flow of relatively large water flow, so that most pollutants in the water can be separated and discharged, thus reducing the accumulation of the pollutants on filtration material, and improving water quality and stability.Cette invention concerne un dispositif de séparation eau-polluant, un dispositif de séparation eau-polluant basé sur dispositif de séparation eau-polluant et filtration, un système de séparation eau daquarium décoratif-polluant et filtration, et un système de séparation eau de culture haute densité-polluant, filtration et aération/oxygénation, lesdits dispositifs ou systèmes comprenant une cuve, un tuyau darrivée deau e
