The biological phosphorus removal system can put in a proper amount of the compound microbial inoculum in time according to the water quality condition, thereby realizing rapid and accurate biological phosphorus removal, avoiding redundant labor time consumption and reducing unstable factors during manual construction. By adding the needle bar algae and the phosphorus-accumulating bacteria, the synergistic phosphorus removal effect is exerted, so that the water quality is rapidly purified. But the system only aims at the index that water pollutes phosphorus.

But only the water body is sterilized by ultraviolet rays, other pollution indexes cannot be treated, and the water is sterilized by ultraviolet rays with poor effect.
Patent CN 103159292a proposes a continuous water treatment device, which comprises a rotary valve and at least two exchange columns, wherein the exchange columns are respectively connected with the rotary valve by pipelines. Compared with the prior art, the invention has the following advantages: the structure is simple, and the use is convenient; the operation steps of water treatment can be effectively simplified, and the possibility of errors is reduced; can continuously carry out water treatment, and greatly improves the efficiency of water treatment. However, the exchange column needs to be subjected to operations such as water production, regeneration, cleaning and the like, and is inconvenient to maintain at a later stage and high in cost.
