摘要
严峻的水环境形势使得我国许多地区的污水厂正面临提标改造,但是进水碳源不足、规划场地受限等诸多因素一直困扰升级改造工艺的选择,常规的应对技术又具有投资大、运行费用高等不足,未必适合我国大部分地区采用,因此甄选投资及运行费用低廉的具有可持续发展特性的新工艺、新技术显得迫在眉睫。侧流污泥生物强化技术近些年在国外得到快速发展和应用,对其中的侧流污泥水解技术、侧流污泥原位生物富集技术、侧流腐殖土污泥培养技术进行了介绍,并对其在升级改造中的适用性进行了分析。
Most wastewater treatment plants are facing with upgrading and reconstruction due to the severe situation of water environment in China. However, the choice of upgrading technologies is hindered by lack of influent carbon source, limited proposed land and many other factors. Because of high investment and operating cost, conventional technologies may not be suitable for use in most parts of China. Therefore, the selection of new process and technology with low investment and operating cost and sustainable development appears urgent. Side-stream sludge bio-augmentation technology has developed and applied rapidly abroad in recent years. Side-stream sludge hydrolysis, in-situ bio-concentration and humus sludge culture are introduced, and their applicability in the upgrading and reconstruction is analyzed.
