Alcohol wastewater is organic wastewater with high concentration, high temperature and high suspended matter. The wastewater in the production process mainly comes from the alcohol lees discharged after distillation and fermentation of mature mash, washing water of production equipment, and cooling water of cooking, saccharification, fermentation and distillation process, etc. The alcohol lees are acidic and the COD is high. In general, polyacrylamide is used in two processes: air floatation of raw water and drying of sludge.
Air flotation treatment can treat the suspended matter in wastewater, the main function is to adsorb and bridge the suspended matter to flocculate into larger particles and lower the resistance to accelerate the rise of suspended matter to achieve the purpose of wastewater treatment. Sludge drying treatment, sludge natural concentration will still have a high water content, the use of mechanical filter press to ensure that the sludge has sufficient filtration water and a certain size of granularity. In this process it is necessary to add polyacrylamide flocculant to achieve flocculation and help rate. Air flotation and sludge press are basically using cationic polyacrylamide.
The specific type of cationic polyacrylamide to be used needs to be determined by the model selection experiment. The effect of polyacrylamide treatment is mainly depends on the degree of coincidence, on the model selection is accurate or not, which is closely related to the size of the selection range, the wider the range, the more models, it is more likely to choose the right model. Guangdong Shouxin Environmental Protection Materials Technology Co., Ltd. is a global polyacrylamide brand with stable quality, after more than ten years of development Shouxin brand polyacrylamide has two obvious advantages.
1. More models of polyacrylamide: there are 107 different models of polyacrylamide, which can provide customers with accurate selection experiments and select the more cost-effective polyacrylamide models for customers.
2. Stability of polyacrylamide products: We can guarantee the stability of the products through professional technical engineers and advanced testing equipment, and do strict double supervision and testing when incoming and outgoing.
Due to the above advantages, Shouxin's polyacrylamide is favored by customers in the alcohol industry and widely used in alcohol factories such as COFCO.
