Therefore, the embodiment establishes the bacteria-algae coupled water treatment system without aeration, and can be used for removing nitrogen and phosphorus from the water body with low cost and high efficiency and removing COD.
Specifically, the pretreatment area of the embodiment comprises a micro-filter 1 and a protein separator 2, the micro-filter 1 is provided with a water inlet, and a water body to be treated is pumped into the micro-filter 1 through the water inlet of the micro-filter 1 by a pump body so as to remove solid suspended matters with the particle size of more than 70 mu m in the water body.

Thus, the water treatment system of the embodiment performs preliminary treatment on the water body through the pretreatment area.
After the water body is subjected to preliminary treatment by the pretreatment area, the water body enters the aerobic bacteria treatment area for further treatment. The aerobic bacteria treatment area comprises a biochemical pool 3, and a water inlet of the biochemical pool 3 is communicated with a water outlet of the protein separator 2. The biochemical tank 3 is internally provided with activated sludge and aerobic bacteria such as nitrifying bacteria, bacillus subtilis, enterococcus faecalis and the like, the activated sludge is domesticated by the aerobic bacteria, and ammonia nitrogen and nitrite in the water body are converted into nitrate.
