The advantages of polyaluminum chloride in the treatment of high-concentration organic wastewater

Polyaluminum chloride(PAC) is usually also called basic aluminum chloride or coagulant. It is mainly used to clarify muddy water. To put it simply, it is to pump the water in the river and the reservoir into the pool and then add polychloride. Aluminum can make water clear, but its reaction with water has time and speed requirements. It is better to use a machine to stir the polyaluminum chloride aqueous solution and water for 15 minutes. Add it to the swimming pool), and then you will see a lot of small yellow particles in the water, that is called sail flower, the sail flower is the product of the combination of impurities in the water and the medicine, and then the sail flower will sink to the bottom of the pool by itself, and the sail flower will sink to the bottom of the pool. Water is clear water.

Polyaluminum chloride has great advantages in the treatment of high-concentration organic wastewater, but it also has certain disadvantages, such as a long start-up time, a high level of management, and easy to produce odor, especially for small scale This is especially true of industrial process engineering. However, in the anaerobic reaction, the methane fermentation stage with long reaction time and high control conditions can be abandoned, and the reaction can be controlled in the acidification stage, which has the following advantages compared with the anaerobic reaction of the whole process:

(1) Since the reaction is controlled rapidly in the hydrolysis and acidification stages, the volume of the hydrolysis tank is small;

(2) There is no need to collect the generated biogas, which simplifies the structure, reduces the cost and facilitates maintenance;

(3) The degradation function of the sludge is completely the same as that of the digester, and the amount of excess sludge produced is small.

(4) Under the action of hydrolase, oil molecules generate glycerol and fatty acids, and macromolecular organic matter is decomposed into small molecular substances. After the hydrolysis reaction, the solubility and biochemical properties in wastewater are improved, which is beneficial to the uptake of substrates by microorganisms and is used in the metabolism of microorganisms. An important link is reduced in the process, which will accelerate the degradation of organic matter and create more favorable conditions for subsequent biological treatment.
