随着污染防治攻坚战的推进,我国污水处理率已超过90%,作为污水处理重要副产物的污泥也伴随污水处理规模的扩大而大量产生。但与高污水处理率形成鲜明对比的则是低于30%的污泥无害化处置率。根据《“十三五”生态环境保护规划》目标的明确指示,2020年底前,地级及以上城市污泥无害化处理处置率将达到90%,污泥处置走出“泥泞“困境已刻不容缓。
With the advance of the battle of pollution prevention and control, the sewage treatment rate in China has exceeded 90%. As an important by-product of sewage treatment, sludge is also produced in large quantities with the expansion of sewage treatment scale. However, in sharp contrast to the high sewage treatment rate, the harmless disposal rate of sludge is less than 30%. According to the clear instructions of the objectives of the 13th five year plan for ecological and environmental protection, the harmless treatment and disposal rate of sludge in prefecture level and above cities will reach 90% by the end of 2020. It is urgent for sludge disposal to get out of the "muddy" dilemma.
据统计,我国目前污水处理总量大约2亿吨/天,粗算产生湿污泥量约为20万吨/天,产量惊人。但由于行业内长期“重水轻泥”,我国每年产生的大量污泥中,约3000万吨没有得到妥善安置,形势不容乐观,污泥处置成为制约污水处理厂良性发展的重要瓶颈。
According to statistics, the total amount of sewage treatment in China is about 200 million tons / day, and the roughly calculated amount of wet sludge is about 200000 tons / day, which is amazing. However, due to the long-term "heavy water and light mud" in the industry, about 30 million tons of sludge produced every year in China have not been properly placed, and the situation is not optimistic. Sludge disposal has become an important bottleneck restricting the sound development of sewage treatment plants.
