Developed by Kimberly-Clark Company, using 100 meter deep well aeration, oxygen is not easy to escape, and the utilization rate can reach over 90%. Sufficient oxygen can fully oxidize and decompose organic pollutants in sewage, thus reaching the discharge standard. Moreover, the amount of sludge produced by this method is only 1/5 of that of ordinary aeration method, and the sludge problem that plagues printing and dyeing enterprises can be solved easily. In addition, because this "deep well" is sealed with steel plates and concrete is poured outside, there will be no leakage and groundwater pollution.
Not only that, "deep well aeration" also saves land, saving 1/50 or even less than ordinary aeration tanks. Shaoxing "Poseidon Printing and Dyeing" is one of the first enterprises to taste the sweetness. "The area is only over 60 square meters, and the daily electricity consumption can be saved by half; It is not easy to rust and corrode, and it can also greatly save maintenance costs. " The person in charge of "Poseidon Printing and Dyeing" said. Now, through this new technology, the enterprise can treat about 4,000 tons of wastewater every day, saving 490,000 kWh of electricity every year. According to the calculation of relevant experts, if Shaoxing13 printing and dyeing enterprises adopt this new technology, they can save 40 million kWh of electricity throughout the year.
At present, Kimberley deep well aeration activated sludge treatment technology has been implemented in Changzhou, Jiangsu, Jiaxing, Zhejiang and Shaoxing. Daiwa Textile, Beihai Printing and Dyeing, Xinao Co., Ltd. and other enterprises have adopted this method to treat wastewater and achieved ideal results.
