| titleOfInvention | A purification process and equipment for fly ash pretreatment of high humus raw water |
| abstract | A purification process and equipment for fly ash pretreatment of high-humus raw water, the purification process includes the following steps: (1) preparation of fly ash suspension; (2) mixing fly ash suspension and coagulant Mix with high-humus raw water for fly ash pretreatment, add fly ash ≥ 20mg per rise in humic raw water during treatment; (3) Add sodium carbonate solution to adjust pH to high humus raw water after fly ash pretreatment Precipitate after 6.5-8.5. The invention also includes equipment used in said purification process. The pretreatment effect of the water purification process of the present invention is good, and the resource utilization of fly ash is realized. When the dosage of fly ash pretreatment is ≥30mg/L, the removal rate of humic acid in high-humus raw water is ≥80%. , The operation, management and maintenance of the equipment is convenient, which can save the cost of water purification. |
