Embodiment Construction
[0041] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:
[0042] Such as figure 1 As shown, a mechanical and plant purification system for artificial culture tail water includes a sedimentation tank 1c, an aeration tank 2c, a mechanical filtration device 3c, an algae purification tank 4c and an ozone disinfection tank 5c. In the sedimentation tank, several partition walls 1c1 are arranged to divide the sedimentation tank into tortuous water flow channels. There is an aeration device at the bottom of the aeration tank. The algae purification pond in this embodiment is a spirulina purification pond or a chlorella purification pond or a Synechococcus purification pond or a salina purification pond or a Phaeodactylum purification pond.
[0043] Such as figure 2 As shown, the mechanical filtering device 3c includes a frame, a garbage collection bucket 17 with an upper end opening, a water suction pipe 3...

Description
technical field [0001] The invention relates to a water body particle cleaning device, in particular to a mechanical and plant purification system for artificial breeding tail water. Background technique [0002] In recent years, with the rapid development of high-density artificial aquaculture and the aggravation of aquaculture environmental pollution, the degree of pollution of aquaculture water far exceeds the purification capacity of the water itself. Pollutants formed by residual feed and fish excrement in the process of artificial aquaculture cause water body self-pollution and even water quality deterioration, manifested as: severe eutrophication of water body, increase of suspended solids in water body, biological oxygen demand, chemical oxygen demand , nitrite nitrogen, etc. content increased, dissolved oxygen decreased. [0003] The traditional aquaculture wastewater treatment method is to discharge the aquaculture water and inject it into a fresh water body; this...
