| titleOfInvention | Purification agent for organic polluted wastewater |
| abstract | An object of the present invention is to treat a polluted wastewater purifying agent that does not re-dissolve and re-elute in a natural state, and is mixed with SS in the polluted wastewater, and is dispersed, suspended and partially dissolved in the polluted wastewater. An inorganic coagulant / precipitant, which can coagulate substances by chemical change with a simpler processing apparatus, is provided. The purifying agent of the present invention comprises a pre-purifying agent and a main purifying agent. The purification pretreatment agent is composed of alums and / or sulfates, and the main purification agent is calcium salt 40 to 60% by weight aluminum sulfate 30 to 50% by weight alkali metal carbonate 15 to 25% by weight organic coagulant 1 About 5% by weight. By using this agent, SS and organic pollutants in polluted wastewater can be separated and removed at the same time, and the sludge separated and recovered by using this agent will be natural as long as strong chemical stress is not applied. It is stable without re-separation in the state. |
