| titleOfInvention | Adsorbing material for phosphorus and heavy metal polluted water and preparation method thereof |
| abstract | The invention provides an adsorbing material for phosphorus and heavy metal polluted water, which comprises a fibrous membrane, an iron slow-release agent and an oxygen slow-release agent, wherein the ratio of the iron slow-release agent to the oxygen slow-release agent is 5-15: 0.5-2, the adsorbing material is prepared by making a fiber membrane into a bag shape and sealing the bag, wherein an iron slow release agent and an oxygen slow release agent are contained in the adsorbing material, and the preparation method comprises the following steps: weighing ferrous sulfate powder, ascorbic acid, beta-cyclodextrin and starch according to a ratio, uniformly mixing and compacting to prepare iron sustained-release agent granules; weighing sodium percarbonate powder, beta-cyclodextrin and starch according to the proportion, uniformly mixing and compacting to prepare oxygen sustained-release agent particles; carrying out hot-pressing sealing on the fiber membrane on a plane packaging machine to form a strip-shaped bag; the iron slow-release agent particles and the oxygen slow-release agent particles are respectively filled into the prepared packaging bags according to the proportion and sealed. |
