制药废水的水质成分复杂、污染物浓度高、COD含量高、含盐量高和降解性差，一直是难以处理的一种工业废水。内蒙古某制药有限公司的废水主要来源为生产三氯异氰尿酸粉料产品时所产生的废水以及冲洗废水，属于高盐有机废水，需要对其进行处理后才可排放入城市污水管道。本文采用物理吸附、电化学氧化、Fenton氧化、低温蒸发四种方法研究了高盐有机废水的处置，试图寻求最适合处理该废水的方式。采用物理吸附方法处理高盐有机废水，能够有效地去除废水中的部分TOC、TN含量。其中，活性炭粉末、活性炭棒和活性氧化铝对高盐有机废水中TOC、TN的去除效果较好。自制的小型吸附柱在处理高盐有机废水时，也能够达到20%左右的TOC、TN去除率，具有一定效果。采用电化学法和Fenton氧化法处理高盐有机废水，仅能够在一定程度上处理废水中的TOC、TN。但是，不能够对废水除盐，并且Fenton氧化法会引入新的离子，提升了废水含盐量，因此处理该废水不适宜采用电化学及Fenton氧化法。采用低温蒸发法处理高盐有机废水，能够快速、高效的去除废水中的无机盐、TOC、TN。在旋转蒸发温度为60-75℃时，旋转蒸发用时的缩短最快，其蒸发的效率最高，能够在达到水质排放目标的同时减低能耗。针对高盐有机废水的特点，设计了采用低温蒸发技术的工艺流程和设备，在真空条件下，63.8℃能够达到最优效益，为工业生产提供了指导。

Pharmaceutical industrial wastewater produces' wastewater has been a serious problem. It has the characteristics of complex composition, high concentrations of pollutants, high COD content, high salinity and poor degradability. In this research, the main sources of pharmaceutical wastewater is a production of TCCA produced by an Inner Mongolia Company. It belongs to high salt organic wastewater and needed to be treated.In this paper, four method were used to treat high salt organic wastewater such as physical adsorption, electrochemical oxidation, Fenton oxidation ,Low-temperature evaporation to treat high salt organic wastewater, which are trying to find the most appropriate way to deal with the waste water.Experiments show that, by using the physical adsorption method for processing high-salt organic wastewater, the part of wastewater can effectively remove the content of TOC, TN. Activated carbon powder, activated carbon and activated alumina rod removal of high salt organic wastewater TOC, TN. By using adsorption column to treat high salt organic wastewater, it is possible to remove about 20% of the TOC, TN.Experiments show that, the electrochemical method and Fenton oxidation treatment can reduce the content of TOC and TN. However, both methods are not able to reduce the salt content in the wastewater, and Fenton oxidation treatment will introduce new ions which enhance the wastewater salinity. Therefore, chemical treatments are inappropriate to this wastewater.Experiments also show that, it can efficiently remove the TOC and TN of the wastewater by using low-temperature evaporation method which can also reduce the number of ions. According to the data, the rotary evaporator can stay at the status of high efficiency of evaporation at the temperature of 60-75 °C which will reduce energy consumption, at the same time achieve the target effluent quality as possibleFinally, based on laboratory studies, this paper combines the characteristics of the rotary evaporator and the characteristics of high salt organic wastewater, design a process and equipment for industrial production which provides guidance by using low temperature evaporation.
