Embodiment 1
[0022] Get 75 kilograms of iron-free aluminum sulfate prepared by crystallization, 13 kilograms of lignin and 12 kilograms of rare earth compounds extracted from food-grade rare earth medical stone ore by extraction and separation technology, and prepare a kind of aerobic high-efficiency biochemical purification agent of the present invention. Aqueous products. This product is used in the domestic sewage treatment of Shanghai Caoyang Sewage Treatment Plant. As a result, the domestic sewage can be reduced from about 60mg / L of ammonia-nitrogen and about 15mg / L of phosphorus TP to ≤15mg / L of ammonia-nitrogen and Tp≤1mg / L, meet the emission standard.
Embodiment 2
[0024] Get 70 kilograms of iron-free aluminum sulfate prepared by crystallization, 15 kilograms of lignin and 15 kilograms of rare earth compounds extracted from food-grade rare earth medical stone ore by extraction and separation technology, and prepare a kind of aerobic high-efficiency biochemical purification agent of the present invention. Aqueous products. This product is used in the printing and dyeing wastewater treatment of Zhejiang Shaoxing Water Treatment Development Co., Ltd. As a result, the CODcr (chemical oxygen demand) in the printing and dyeing wastewater can be reduced from 1800mg / L to ≤120mg / L, and the chromaticity can be reduced from about 450 (dilution times ) dropped to ≤50, SS (suspended solids) dropped from about 300mg / L to ≤30mg / L, meeting the discharge standard.
Embodiment 3
[0026] Take 80 kilograms of iron-free aluminum sulfate prepared by crystallization, 10 kilograms of lignin and 10 kilograms of rare earth compounds extracted from food-grade rare earth medical stone ore by extraction and separation technology, and prepare an aerobic high-efficiency biochemical compound of the present invention. Water purifier products. This product can be used for sewage treatment in general sewage treatment plants.
