摘要

血液透析用水是生产透析液和消毒发生器所必需的基本要素。每个病人的血液透析疗程大约需要 120 升过滤水。阿苏特大学医院的血液透析设施每天治疗 300 多名病人,每年进行 85,000 多次血液透析。这项研究包括对血液透析废水和处理装置废水的细菌学和物理化学质量进行评估。采集的样本按照废水分析的标准方法进行检测。理化调查的重点是潜在氢(pH 值)、电导率(EC 值)、化学需氧量(COD 值)、生化需氧量(BOD 值)、氯化物、溶解固体总量(TDS 值)、镁(Mg 值)、钾(K 值)、钙(Ca2 值)、氮(N 值)、磷(P 值)、钠(Na 值)、氯化物(Cl 值)、碳酸氢盐(HCO3 值)、油脂、总酚的含量。此外,还通过膜过滤法对粪大肠菌群进行了计数,并通过微生物学调查对链球菌和铜绿假单胞菌进行了搜索。研究结果表明,未经处理的污水不能直接用于灌溉。需要事先进行处理,以提高废水的质量。重金属铅 (Pb)、汞 (Hg)、铁 (Fe)、钴 (Co)、银 (Ag)、镍 (Ni)、镉 (C) 和锰 (M) 的检测结果显示符合可接受的标准。研究回收利用阿苏特大学医院血液透析中心污水的可能性是有益的。这是否有助于节约水资源和保护环境?研究再利用或回收的可能性至关重要。这项研究通过评估血液透析废水回用的可行性,使人们开始关注这一被忽视的课题,尤其是在血液透析治疗中。

Characteristics and quality analysis of wastewater resulting from medical uses ‎in Assiut University Hospitals: A case study on hemodialysis wastewater and ‎reverse osmosis reject water
Hemodialysis water is an essential element necessary for the production of dialysates as well as ‎disinfection generators. Each patient's hemodialysis session requires around 120 liters of filtered ‎water. Assiut University Hospitals' hemodialysis facilities treat more than 300 patients each day and ‎perform over 85,000 hemodialysis sessions per year. This study includes an evaluation of the ‎bacteriological and physicochemical quality of blood dialysis waste and water rejected from the ‎treatment units. Samples were collected and tested in accordance with standard methods of ‎wastewater analysis. The physicochemical investigation focused on the extent of potential hydrogen ‎‎(pH), electrical conductivity (EC), chemical oxygen demand (COD), biochemical oxygen demand ‎‎(BOD), chloride, and total dissolved solids (TDS), as well as Magnesium (Mg), Potassium (K), ‎Calcium (Ca2), Nitrogen (N), Phosphorus (P), Sodium (Na), Chloride (Cl), Bicarbonate (HCO3), Oil ‎& Grease, total phenol. Also, enumeration of fecal coliforms was performed by membrane filtration ‎and searches for Streptococci sp. and Pseudomonas aeruginosa were conducted through ‎microbiological investigation. According to the findings, untreated effluents cannot be used directly ‎for irrigation. Prior treatment is required to improve the quality of the wastewater. The results for ‎the heavy metals Lead (Pb), Mercury (Hg), Iron (Fe), Cobalt (Co), Silver (Ag), Nickel (Ni), ‎Cadmium (C), and Manganese (M) revealed compliance with acceptable norms. It would be ‎beneficial to investigate the possibility of recycling effluent from Assiut University Hospital's ‎hemodialysis center. Which leads to saving water resources and protecting the environment? It is ‎critical to investigate the possibility of reusing or recycling it. This work brings attention to this ‎neglected subject, particularly in hemodialysis therapy, by evaluating the feasibility of hemodialysis ‎wastewater reuse.‎
