Polyaluminium chloride treatment of power plant wastewater

source:xsj992.cn time:2017-11-22 09:46

Polyaluminium chloride treats power plant wastewater. Each city has a power plant, which is a medium that relies primarily on water to transfer energy during operation. Power plant wastewater sources are very wide, complex components, oily wastewater, desulfurization wastewater, ash wastewater, acid and alkali wastewater, etc. are mixed together, it is difficult to handle. As the country attaches importance to environmental protection, it is especially important for power plant wastewater treatment.

Common power plant wastewater treatment methods include activated sludge process, contact oxidation process, facultative biological method and chemical treatment method. Lvyuan clean water reminds you that there are several types of industrial wastewater, domestic sewage, coal-containing wastewater, acid-base wastewater, and the selection of treatment methods according to classification. The process is different.

The polyaluminium chloride water purifying agent commonly used in power plant sewage treatment is used in combination with an organic flocculant. If the flocculant is used alone, it needs to be high concentration to be effective. After using the polyaluminium chloride, the amount of the organic flocculant can be greatly reduced. This makes it possible to prevent the flocculant from being deposited on the heat exchange surface of the cooling tower or the like due to the large amount, thereby accelerating the corrosion and scaling of the equipment. When treating power plant wastewater, we generally choose 28% polyaluminium chloride water purifying agent for AL2O3.
