摘要本文所针对的废水来源于一家进行机械加工工厂的表面处理废水，进行水质测试后，发现废水中磷和铁的含量明显过高，未达到该地区的废水排放标准，决定先进行实验室小试，确定了除磷剂和除铁剂，除铁剂分别为TMT和DTC，经过多种条件下不同浓度的去除剂去除效果的实验，发现TMT比DTC相对来说更加出色，而除磷与除铁的pH值分别为8.0和8.5左右，在此基础上进行工程设计与施工，最终的调试结果除磷和除铁在pH分别为8.1和8.6达到了最高，为88.3%和96.9%，完全达到了设计要求和排放标准。近几年由于工业污水排放严重超标，导致水污染加剧，因此废水的治理受到越来越多的重视，对工厂进行污水治理工程是废水治理的必由之路，这也是本次设计的意义所在。44221
Abstact Surface treatment of waste water from the in a mechanical processing plants, water quality testing, found that the content of phosphorus and iron in the waste water was too high, has not reached the area of wastewater discharge standards, decided to conduct experiments in the laboratory, the phosphorus removing agent and in addition to iron, in addition to iron are respectively TMT and DTC through a variety of conditions, different concentrations of remover removal experiments found that TMT is more excellent than DTC, and the removal of iron removal and pH values were 8 and 8.5, the design and construction of Engineering on the basis of this, the final result of phosphorus and iron in pH were 8.1 and 8.6 reached the highest, was 88.3% and 96.9%, fully meet the design requirements and the emission standard. In recent years, the industrial wastewater discharge seriously exceeded, resulting in the deterioration of water pollution, and waste water treatment has been paid more and more attention, sewage treatment project of wastewater treatment plant is the only way, this is where the significance of this design.
