制药废水中污染物组分繁杂，具有污染物含量高、COD值高、难以生物降解物质多、有毒有害物质多等特点，因此制药废水已经逐渐成为重要的水质污染源之一。而发酵过程是制药工艺中极为重要的一个环节，发酵工程制药废水的治理尤为重要。 本设计对一药用氨基酸发酵工业废水处理厂进行了工艺流程、工艺参数、构筑物尺寸等的初步设计。在整个设计过程中，严格遵循相关的专业规范的要求，参考相关资料和有关最新的国家标准规范，根据设计要求和求新的思想，通过工艺比选，确立了以加压上流式厌氧污泥床（UASB）和周期循环活性污泥法（CASS）为处理核心，辅以调节池、混凝沉淀池、接触消毒池等处理构筑物的工艺流程。本设计工艺流程简单，通过酸碱调节池和混凝沉淀减少有毒有害物质，提高废水可生化性，后续利用UASB和CASS对有机污染物进行有效的生物降解，而且省去了初次沉淀池、二次沉淀池和污泥消化系统，节省了基建投资和运行费用，并能保证出水达到废水排放标准，做到了水资源的合理利用。 |

Pharmaceutical wastewater contains complex mixtures of contaminants with high levels, along with its other characteristics such as, high COD value, large quantities of difficult biodegradable, toxic, and hazardous substances, thus the pharmaceutical wastewater has gradually become one of the most important water pollution sources. Since the fermentation process is a very important part of the pharmaceutical process, the treatment of fermentation engineering pharmaceutical wastewater is particularly important. This study focus on the preliminary designs of technological process, process parameters, structure dimensions for a medicinal amino acid fermentation industrial wastewater treatment plant. In the whole design process, we strictly followed the relevant professional regulatory requirements, referred to the relevant information and the latest national standards, according to the design requirements and innovation thinkings. Through the election of process, we established the technical process with the processing core by using pressurized Upflow anaerobic sludge blanket (UASB) and Cyclic Activated Sludge System（CASS）, supplemented by regulation pool, coagulation-sedimentation tank, and contact disinfection tank and other treatment structures. This process designed is simple, and to reduce the toxic and hazardous substances and improve the biodegradability of wastewater, by pH regulation pool and coagulation-sedimentation tank. Then the following UASB and CASS were used to realize the effective biological degradation of organic pollutants. This process eliminates the need for primary sedimentation tank, secondary sedimentation tank and sludge digestive system, which saves the investment in infrastructure and operating costs, guarantee that the effluent can meet the wastewater discharge standards, and also realize the rational utilization of water resources. |
