What is the principle of the acid-base neutralization water treatment method? Author: pH in wastewater and water treatment method is a method for wastewater treatment industrial wastewater treatment process common acid-base and water have different operations. Today, the editor will specifically introduce to you what is the principle of the acid-base neutralization water treatment method? Intermediate neutralization of environmentally friendly acid and alkali wastewater 1. When the water quality and quantity change small or the wastewater buffer capacity is large, or the subsequent structure has a large range of pH requirements, the flow mixing and reaction can be continuously performed in the collection well, pipeline, and mixing tank The neutralization pool is not set separately. 2. When there is little change in water quality and quantity, and the wastewater has a certain buffer capacity, a separate continuous flow neutralization tank should be set up to ensure the pH value of the effluent. 3. When the water quality and volume change greatly, and the water volume is small, the continuous flow neutralization tank cannot guarantee the PH value of the effluent, or the effluent quality is high, or the wastewater contains other impurities or heavy metal ions, a more stable method It uses intermittent neutralization tank. At this time, there should be at least two neutralization tanks for alternate use. The volume of each pool can be calculated based on the amount of wastewater discharged in one shift or one day and night. Environmental protection agent neutralization equipment and facilities 1. There are two methods for adding neutralizer: dry method and wet method. The equipment used and the method of adding coagulant are the same. 2. The mixed reaction tank is generally a baffle-type mixed reaction tank, which uses compressed air or mechanical stirring, and the sedimentation tank generally uses an advection sedimentation tank. Filter and neutralize facilities. There are two types of filtration and neutralization equipment: gravity neutralization filter and upflow expansion filter.
