摘要
目前,大部分污水处理厂面临着进厂碳源浓度不足的问题,导致系统生物脱氮除磷效果不佳,影响出水水质效果。为提高系统的可生化性,大部分污水处理厂采取的措施为额外投加碳源,最常见的碳源种类是葡萄糖,但同时药耗的增加提高了厂内的运行成本。为降低运营成本,响应落实节能降耗工作,采取必要的措施降低药耗是未来污水处理行业的重要改革方向,其中如何充分挖掘内碳源、优化运行工艺、选择合适外加碳源等均是可探讨的技术研究方向。
At present,most sewage treatment plants are facing the problem of insufficient carbon source concentration,which leads to poor-effective of biological denitrification and dephosphorization,thus affecting the effluent water quality.Most wastewater treatment plants take the measure of adding additional carbon sources to improve the biochemical properties of the system,and the most common type of carbon source is glucose,which increases the operating costs of the plant.In order to reduce operating costs and respond to the implementation of energy conservation and consumption reduction,it is an important reform direction for the future sewage treatment industry to take necessary measures to reduce drug consumption,in which how to fully exploit the internal carbon source,optimize the operation process,select the appropriate additional carbon source,etc.are the technical research direction can be explored.
