Decolorization treatment method of high color wastewater by polyferric sulfate

High chroma wastewater is easy to cause visual angle pollution, affect photosynthesis of plants in the water, and destroy the ecological balance in this section of water. In addition, high chroma wastewater is generally caused by pollutants such as iron, copper and heavy metals, which will have a great impact on water, animals and plants and human body.

In the practical application of high chroma wastewater treatment, complex alkali, flake alkali, etc. are usually added as required to adjust the pH value, so that the pH value environment in the water can reach its better treatment range. In addition, a small amount of polyacrylamide is added as coagulant aid to improve the treatment efficiency and reduce the total cost of wastewater treatment.

The concentration of the product we usually refer to is actually the content of the product. polyferric sulfate is mainly composed of solid and liquid products with different contents. Generally speaking, the content of solid products in sewage treatment agents is close to twice that of liquid products. Therefore, the content of the liquid polyferric sulfate product is not particularly high, preferably 10% - 11%. So, what effect does its concentration change have on sewage treatment?

As a polymer water purifying agent, liquid polyferric sulfate can be used to flocculate high chroma wastewater. Based on the principles of electric neutralization, compression of electric double layer, bridging adsorption and sedimentation, through the precipitability of suspended particles in the water, it will settle under the action of gravity, and then through solid-liquid separation, the colored particles in the water will be discharged into the water by sludge discharge. The higher the concentration of polymeric ferric sulfate, the higher the purity. From the perspective of content, the lower the dosage will be. This product is applicable to domestic sewage, municipal sewage, food wastewater, paper-making wastewater, printing and dyeing wastewater, etc. except for the wastewater with high concentration, it is generally diluted with water before adding. The higher the concentration, the less the dosage of chemicals. However, it should be noted that the dosage is adjusted and determined according to the concentration of sewage.

If the dosage is too small, the flocculation effect will be poor, unable to meet the treatment standard, or even unable to achieve the flocculation effect. Too much dosage or too high concentration will also cause the sewage to change from turbid to clear and then turbid, or poor sedimentation of pollutants and waste of chemicals. The concentration of polyferric sulfate required to be added has a great relationship with the concentration of water quality, water quantity and dosage. Products with high content and good stability can be purchased, and then the dosage can be adjusted and determined according to the demand, so as to reduce the dosage, save the cost and total cost.
