| titleOfInvention | Preparation method of ecological flocculating agent for removing phosphorus and algae in eutrophic water body |
| abstract | The invention relates to a preparation method of an ecological security flocculating agent for effectively removing phosphorus and algae in a eutrophic water body. The preparation method comprises the following steps of preparing materials, uniformly mixing original clay with water to obtain clay suspension, adjusting the basicity to 50-90% by dropping dilute acid into the clay suspension, uniformly mixing aluminium polychlorid powder with water to prepare aluminium polychlorid solution, adjusting the basicity to 50-90% by dropping dilute acid or dilute alkali into the aluminium polychlorid solution, pouring the aluminium polychlorid solution into the clay suspension, standing and curing at 50-80 DEG C to obtain curing solution, drying the curing solution at 50-80 DEG C, and crushing and sieving to obtain the flocculating agent. According to the invention, the removal rate of total phosphorus is 93% or more; the removal rate of CODCr is 53% or more; the removal rate of total nitrogen is also above 3%; the removal rate of water-blooming cyanobacteria is 96% or more; the removal rate of algal toxin MC-LR is 7% or more; and the risk in rapidly releasing algal toxin is not caused. |
