I. The basic principle of welding fume treatment equipment
Aiming at the toxic and harmful substances in the influent water to microorganisms, the composite oxidant, composite reducing agent, composite flocculant, and coagulant aid are catalyzed into the inflow water by agreeing to the structure in the pretreatment unit. Various physical and chemical reactions such as oxidation, reduction, flocculation, adsorption, precipitation, etc., are carried out through the coupling of two efficient water treatment processes: inclined plate precipitation and air flotation, which remove, transform and reduce their toxicity.
1. Catalytic oxidation, reduction, flocculation, adsorption, precipitation, a variety of physicochemical reactions and inclined plate precipitation, air-float coupling technology.
2. Compound oxidant, compound reducing agent, compound flocculant formulation technology.
3. Dissolved air flotation technology, inclined plate precipitation technology.
4. Fenton, Fenton-like advanced oxidation technology.
Main equipment and operation management of welding fume processing equipment
I. Main equipment physical and chemical pretreatment structure, biochemical pool, accident pool, blower room, deodorization workshop, production control scheduling center. The core part of the technology is an efficient reaction separation tank, which contains mixing, flocculation, inclined plate sedimentation and air flotation.
Second, the operation management operation mode is divided into normal operation mode and error operation mode.
In the normal operating mode, the physical and chemical reaction system operates in two ways. The first is to maintain the operating state with the lowest dosage, and the second is the non-dosing operating state.
