Process flow and characteristics of treating paint wastewater with Polyaluminum chloride(PAC) (from the perspective of YuXinHuan Water Treatment)
Paint wastewater, as one of the common pollutants in industrial production, contains a large amount of organic solvents, heavy metals, and other harmful substances, posing a serious threat to the environment. Yuxin Environmental Chemical, as a professional water treatment solution provider, uses Polyaluminum chloride(PAC) as the core precipitant to provide an efficient and economical solution for the treatment of paint wastewater.
1、 Process flow
Pre treatment stage: Firstly, preliminary physical treatment is carried out on the paint wastewater, such as grid filtration, regulating tank homogenization, etc., to remove large impurities from the wastewater and regulate the water quality.
-
- Chemical precipitation: PAC colloidal particles react chemically with suspended solids, organic matter, and heavy metal ions in wastewater to form stable precipitates. During this process, PAC has a fast precipitation rate and can quickly separate pollutants from wastewater.
- Solid liquid separation: Separate the formed precipitate from the supernatant through a sedimentation tank or filtration equipment. After the supernatant meets the emission standards, it can be directly discharged or further processed; Sediments require subsequent disposal.
- Sludge treatment: The generated sludge contains a high concentration of pollutants and requires dehydration, drying, and other treatments to reduce sludge volume and facilitate transportation and disposal.
2、 Processing characteristics
- Efficient removal of pollutants: PAC has excellent precipitation and adsorption properties, which can efficiently remove suspended solids, organic matter, and heavy metal ions from wastewater, significantly reducing the pollutant content in wastewater.
- Easy to operate: The process of treating paint wastewater with PAC is simple to operate. Simply add PAC in proportion to the wastewater and stir and mix, without the need for complex equipment and processes.
- Economical and practical: The dosage of PAC is relatively small, which can effectively save costs. At the same time, the PAC products provided by YuXinHuan Water Treatment have high cost-effectiveness and are suitable for the wastewater treatment needs of small and medium-sized enterprises and individuals.
- Environmentally friendly: Although sludge is generated during PAC treatment, the sludge treatment solution provided by YuXinHuan Water Treatment can ensure proper treatment of sludge and avoid secondary pollution to the environment.
3、 Precautions
- Sludge treatment: The sludge generated during the PAC treatment of paint wastewater needs to be properly disposed of to avoid secondary pollution to the environment.
- Water quality monitoring: During the treatment process, it is necessary to regularly monitor water quality indicators to ensure that the treatment effect meets the discharge standards.
- Technical support: For paint wastewater containing high concentrations of organic solvents, it may be necessary to combine other treatment technologies to improve the treatment effect.
In summary, the process flow of treating paint wastewater with Polyaluminum chloride(PAC) provided by YuXinHuan Water Treatment has the characteristics of high efficiency, simplicity, economy, and environmental protection. By using PAC treatment technology reasonably, paint wastewater can be effectively purified, protecting the environment and human health.
