The invention discloses a
solar power nitrogen and
phosphorus removal biological box array used for in-situ purification for eutrophic slow flow
water body. The biological box array uses longitudinal array or other array combination, and the biological box array is composed of different functions of biological box monomers with similar shape. The biological box
monomer comprises a body framework, a floating body, a photovoltaic power
system, an
aeration or flow pushing facility and a biological box; the biological box body is a stainless steel box body or a plastic mesh cage, and combined biological carrier is filled in the box body. The biological boxes are divided into aerobic biological boxes and anoxic biological boxes which are combined into the array in a certain mode. An
aeration plate is arranged at the bottom of each aerobic box body, and the arrangement of the flow pushing facility is determined according to the
water flow. The
solar power nitrogen and
phosphorus removal biological box array used for the in-situ purification for the eutrophic slow flow
water body uses the combined biological carrier with special proportion and uses step-by-step
nitrification and
denitrification, the filler use ratio can be effectively improved, and accordingly the purification efficiency can be improved. The
solar power nitrogen and
phosphorus removal biological box array does not depend on the
plant, and the
disadvantage that a
plant type
floating island is difficult to manage is avoided. The solar power nitrogen and phosphorus removal biological box array is not limited by the power supply condition by means of using solar
clean energy.
