Paint is a product mainly processed with vegetable oil as the main raw material. It mainly contains resin, vegetable oil, mineral oil, additives, pigments, solvents, heavy metals, etc. Its color is ever-changing and its composition is complex and diverse. Direct discharge will cause serious pollution to the water body, seriously threatening human health and destroying the ecological balance.
Characteristics of paint wastewater quality:
1. Wastewater is discharged indirectly. The concentration of pollutants in paint wastewater varies greatly over time. At the same time, the water quality components are complex and vary greatly. With the different processing techniques, the overall water volume and water quality vary greatly, which brings great difficulties to the biochemical treatment of sewage.
2. The concentration of organic matter is high and the composition is complex. Most of them are high-molecular organic matter, which is difficult to biodegrade.
3. The chromaticity is extremely high and diverse.
4. The nutrients in the sewage are single and lack some nutrients necessary for microbial production.
5. The concentration of suspended solids is high.
6. It contains some toxic substances. When the toxicity is high, it will affect the biochemical effect. At this time, it must be effectively absorbed and reacted before treatment.
Analysis of treatment difficulties
The main difficulties in the treatment of paint are that it contains a variety of toxic substances in oil, high concentration of organic matter, complex pollutant composition, difficult biodegradation, high solid content, etc., which make the treatment of paint wastewater difficult.
Yixing Cleanwater Chemicals Co., Ltd.’s Coagulant For Paint Fog is generally divided into two components, A and B. Agent A is a special treatment agent that can decompose and remove the viscosity of various types of paints. Its main component is a special organic polymer. It is especially suitable for adding to the circulating water system of the paint spraying room to decompose and remove the viscosity of residual paint, remove heavy metals in the paint in the water, and control the biological activity of the circulating water, so that the circulating water is not easy to produce odor, and at the same time reduce the COD content and wastewater treatment costs. Agent B is a special polymer that can remove the sticky paint residue and condense and suspend it to achieve a complete floating effect, which is easy to remove.
