医院污水处理的主要特点
Main Characteristics of Hospital Sewage Treatment
现阶段,国内医院对污水处理的主要有两种方法:
At present, there are two main ways for domestic hospitals to treat sewage:
第一,利用消毒剂进行消毒之后将其排入市政下水道。
First, disinfectants are used to disinfect and then discharged into municipal sewers.
第二,对污水采取生化处理并在消毒之后向自然水体中排放。这两种污水处理方式的主要特点表现在:首先,病原微生物浓度较高,医疗单位对污水的消毒达不到合格标准。
Secondly, the sewage is treated biochemically and discharged into natural water after disinfection. The main characteristics of these two sewage treatment methods are as follows: first, the concentration of pathogenic microorganisms is high, and the disinfection of sewage by medical units can not meet the qualified standards.
尤其大多医院在规模缩小、等级降低之后,其消毒方法、污水处理设备以及自我检测方面的完善程度也呈现递减趋势。其次,消毒过程中主要以氯为主。国内大多地区目标所采用的一般为一级或二级处理加氯消毒、次氯酸钠消毒剂或者利用液氯、二氧化氯进行消毒。
Especially after the scale of most hospitals has been reduced and the level has been reduced, the improvement of disinfection methods, sewage treatment equipment and self-detection has also shown a decreasing trend. Secondly, chlorine is the main disinfection process. In most areas of China, the target is to use chlorinated disinfectant, sodium hypochlorite disinfectant or liquid chlorine or chlorine dioxide for disinfection.
第三,消毒剂投加量过量或不足的情况比较常见。一部分医院为保证杀菌比较彻底,使用过量的消毒剂,也有部分医院为节约成本,投加量明显不足,达不到良好的消毒效果。
Thirdly, excessive or insufficient dosage of disinfectant is common. In order to ensure complete sterilization, some hospitals use excessive disinfectants. In order to save costs, some hospitals have obviously insufficient dosage, which can not achieve good disinfection effect.
