表面曝气叶轮是最近二十多年来国际上发展的一项新设备。美、苏、日、英等资本义国家,把表面曝气叶轮制造技术作为专利,实行垄断,有关这方面的详细资料比较缺乏。文化大革命中,在毛主席革命路线的指引下,在轻工业部的领导下,以安徽纺织印染总厂为主,在河北印染厂、山东济宁印染厂、山西印染厂、四川第一棉纺织印染厂的协作下,成立了三结合叶轮会战小组。小组坚持“独立自主,自力更生”的精神,经过近一年时间的努力,进行八百多次试验,设计了三十七种不同型式的叶轮,制成泵型表面曝气叶轮。目前在印染、煤气、石油化工、农药等各方面工业废水处理中都广泛采用。据不完全统计,全国已有五十多个企业采用,有数百台泵型叶轮在运转中。
Surface aerating impellers are a new device developed internationally in the last two decades. The US, the Soviet Union, Japan, and Britain, capital-meaning countries, have used the surface aeration impeller manufacturing technology as a patent and implemented a monopoly. The detailed information on this aspect is relatively lacking. During the Cultural Revolution, under the guidance of Chairman Mao’s revolutionary line, under the leadership of the Ministry of Light Industry, Anhui Textile Printing and Dyeing Plant was the mainstay, and Hebei Printing and Dyeing Factory, Shandong Jining Printing and Dyeing Factory, Shanxi Printing and Dyeing Factory, and Sichuan No. 1 Cotton Textile Printing and Dyeing Factory. With the collaboration, a three-combined impeller battle group was established. The group adhered to the spirit of “independent, self-reliant, self-reliant”. After nearly a year of hard work, it conducted more than 800 trials and designed 37 different types of impellers to make pump-type surface aeration impellers. It is widely used in the treatment of industrial wastewater in various aspects such as printing and dyeing, gas, petrochemicals, and pesticides. According to incomplete statistics, more than 50 enterprises have adopted the country and there are hundreds of pump impellers in operation.
