| titleOfInvention | Biomass phosphorus-locking agent and method for removing phosphorus from bottom mud of polluted water body in situ |
| abstract | The invention relates to the technical field of sewage treatment, and discloses a biomass phosphorus locking agent and a method for removing phosphorus in bottom sludge of a polluted water body in situ. The biomass phosphorus-locking agent comprises: dehydrated sludge, plant fiber powder, organic food waste, clinker and shell powder. The mixed sludge is mixed with the bottom sludge near the root system of the hydrilla verticillata, and has good removal effect on the phosphorus in the bottom sludge of the polluted water body. The invention provides an in-situ phosphorus removal method for sediment of a polluted water body, which adopts fermented sludge and shell powder to prepare a biomass phosphorus locking agent and is combined with large submerged plants. The biomass phosphorus locking agent can effectively control phosphorus to be released to a water body, can convert part of solid phosphorus in the bottom sediment into plant absorbable phosphorus, can provide nitrogen, mineral elements and other nutrient substances for plants, effectively combines the advantages of a chemical phosphorus locking method and plant absorption, and achieves the purpose of efficiently removing the bottom sediment phosphorus in situ. |
