Treatment Process of Fluoride-containing Wastewater
The cost of fluoride wastewater treatment is high, especially for small and medium-sized enterprises, and the initial investment and operating costs may be stressful. In addition, whether the processed fluorine concentration can be stable to the standard, to avoid fines or production, this is also the customer is very concerned about.
The selection of the treatment process of fluorine-containing wastewater can effectively solve the problem of fluoride ion exceeding the standard
1. Fluorinated wastewater in the photovoltaic / semiconductor industry
Characteristics: Hydrofluoric acid, low PH, high fluoride (200-500mg / L)
High effluent requirements: fluoride ion needs <1mg / L
Recommended process: chemical precipitation-two-stage RO membrane- -ion exchange resin
2. Metallurgical industry / electrolytic aluminum industry
Wastewater characteristics: high fluorine (50-200 mg/L), high sludge disposal cost
Recommended process: electroflocculation and oil removal- -lime precipitation calcium fluoride (CaF 2) purification
3. Chemical / pesticide fluoride-containing wastewater
Characteristics of wastewater: containing machine fluorine, ingredients responsible for
Recommended process: advanced oxidation (O3 / UV) breaking aluminum salt coagulation activated carbon adsorption
In practical application, it is necessary to combine water quality testing and pilot experiment optimization, pay attention to multiple experts, and provide lower cost pharmaceutical solutions.
