本文利用细菌学、寄生虫学及化学等指标对城市大型污水处理厂污水二级处理的效果及污泥中温消化的效果进行了不同月份的监测和评价。并用Ames试验方法对污水致突变活性物去除效果进行了观察。通过与国内外报告资料相比肯定了城市大型污水处理厂对城市污水进行二级处理,生物性污染物的去除效果是好的。其中BOD可去除92.2-98.2%、大肠菌群可去除74.6—99.6%,蠕虫卵可去除96.5—97.1%、肠道致病菌检出率由100%降至33.3%。城市污水中含有一定致突变物质,经二级处理后水中致突活性明显下降。污泥中温消化,对杀灭肠道致病菌是显著的,但蠕虫卵去除率仅40.3%,消化后污泥仍有大量蠕虫卵且活卵占60%。并通过监测提出了污水、污泥处理尚存问题。

In order to seek for the more effective and economic disposal system of foul water in hospital, the serial survey end experimental and spot inves- tigations were conducted early and late. The results showed: The disinfection must be taken as key link in treatment of foul water in hospital; after primary treatment and chlorination, when the product value of concentration (mg/L) multiplied by the time (min. ) achieved to 240 (oridinary hospital)and 540 (tuberc- ulosis hospital), the content of suspended substances (SS) fell to 37mg/L; the clearance rate of SS achiev- ed to 82%; the BOD_5 fell to 35mg/L; the BOD_5 descreased to 42%; the value of bacteria coli was less than 9 thalluses/L, the killing rate achieved to 99.99999%; the intestine pathogens and tubercul- osis bacillus were completely wiped out. The sludge from foul water can be treated with lime (Ca(OH)2) and when the pH value rose to 12, the requirement of disinfection was satisfi- ed and both the sludge and foul water all can be drained; the aeration of sewage through shooting flow, bicchlorination combined with sediment pas- sing rectining tube is a effective way for the sec- ondary treatment of foul water in hospital. In addition, we developed the double siphon equipments with waterpower-automatic controller, the WD-700 flowmeter, the anticorrosive paint coa- ting the contact pond; according to test parameters, we designed and painted a simplified evaluation graph for the use of surveillance. Above investigations well resolved the technic problems of foul water in hospital, and provided the scientific basis of foul water treatment in hos- pital.

我们为寻找一套效果好又较节省的医院污水处理系统,先后进行了一系列调查、实验研究和现场研究。结果证明:医院污水处理应以消毒为主,综合性医院和结核病医院污水经一级处理和氯化消毒,浓时积值(ms/LXmin)分别为240和540,处理后SS含量37mg/L,去除率82%,BOD_535mg/L,下降率42%,大肠菌群<9个/L,杀灭率99.99999%,肠道致病菌和结核杆菌全部灭活。医院污泥用熟石灰消毒,使pH达到12。污水和污泥均达到了安全排放要求。结果还证明:射流暴气、生物氧化与斜管沉淀相结合,是医院污水二级处理较好的方法。此外,我们还研制成水力自控双虹吸投氯装置、WD-700型计量浮杯,筛选出接触池防腐蚀涂料,根据实验请参数,设计、绘制了简化监测用“评价图”等。上述研究较好地解决了医院污水处理的技术问题,为开展医院污水处理工作提供了科学依据。
