Can Polyacrylamide Be Used In Power Plant Wastewater Treatment?
There are many sources of power plant wastewater, which are mainly divided into the following categories: ash washing wastewater, desulfurization wastewater, chemical wastewater and oily wastewater. Polyacrylamide is used in various types of wastewater from power plants. The wastewater from thermal power plants has the following characteristics: the water quality and quantity vary greatly, and there are many types of wastewater classified; the pollutants in the wastewater are mainly inorganic substances, and the organic pollutants are mainly oil; there are many intermittent drainages.
The sources and water quality characteristics of power plant wastewater are summarized in:
1. Ash flushing wastewater treatment
The first idea for gray water treatment is to reduce the amount of water used, and the second is to treat wastewater for reuse or meet discharge standards. Polyacrylamide PAM plays a vital role in the treatment process. Only water with good flocculation and sedimentation effects can be treated and reused up to standard!
2. Desulfurization wastewater
The impurities in desulfurization wastewater from thermal power plants come from flue gas and limestone used for desulfurization, and mainly include suspended solids, supersaturated sulfites, sulfates and heavy metals: many of which are the first type of pollutants required to be controlled in environmental protection standards. Due to the special water quality nature, it is difficult to treat desulfurization wastewater.
3. Treatment of chemical wastewater and oily wastewater from power plants
The general term for various industrial drainage in power plants, including industrial cooling water drainage, chemical water treatment system acid-base regeneration waste liquid, coal conveying system flushing wastewater, oily wastewater, cooling tower sewage wastewater, etc.; the pollutant types and emissions of various types of wastewater The amount changes at any time, making the composition of industrial wastewater very complex. The pollutants in industrial wastewater are mainly organic matter, oil and suspended matter.
