Large, laboratory scale biological treatment tests of real industrial wastewater, generated in a large industrial laundry facility, was conducted from October 2014 to January 2015. This research sought to develop laundry wastewater treatment technology which included tests of a two-stage Moving Bed Bio Reactor (MBBR); this had two reactors, was filled with carriers Kaldnes K5 (specific area - 800 m/m) and were realized in aerobic condition. Operating on site, in the laundry, reactors were fed actual wastewater from the laundry retention tank. The laundry wastewater contained mainly surfactants and impurities originating from washed fabrics; a solution of urea to supplement nitrogen content and a solution of acid to correct pH were added. The daily flow of raw wastewater Qd varied from 0.6-1.0 m/d. Wastewater quality indicators showed that the reduction of pollutants was obtained: BOD by 95-98%, COD by 89-94%, the sum of anionic and nonionic surfactants by 85-96%. The quality of the purified wastewater after the start-up period met legal requirements regarding the standards for wastewater discharged into the environment.
2014 年 10 月至 2015 年 1 月，对大型工业洗衣厂产生的实际工业废水进行了大型实验室规模的生物处理试验。本研究旨在开发洗衣废水处理技术，包括两级移动床生物反应器（MBBR）的测试；该反应器有两个，填充了 Kaldnes K5 载体（比表面积-800 m/m），并在有氧条件下运行。在现场，在洗衣店，将来自洗衣池的实际废水送入反应器。洗衣废水中主要含有表面活性剂和来自洗涤织物的杂质；添加尿素溶液以补充氮含量和酸溶液以校正 pH 值。原废水的日流量 Qd 从 0.6-1.0 m/d 不等。废水质量指标表明，污染物的去除率达到：BOD 为 95-98%，COD 为 89-94%，阴离子和非离子表面活性剂的总和为 85-96%。启动期后净化废水的质量符合排入环境的废水标准的法律要求。
