Description
技术领域technical field
本发明涉及一种污水处理方法，特别是用于微絮凝过滤或者混凝沉淀过滤的自动加药控制方法。The invention relates to a sewage treatment method, in particular to an automatic dosing control method for micro-flocculation filtration or coagulation sedimentation filtration.
背景技术Background technique
目前，全世界都面临着水资源短缺的问题，作为有限资源，水的再生回用即污水深度处理成为了唯一解决问题的途径。At present, the whole world is facing the problem of shortage of water resources. As a limited resource, the recycling of water, that is, the advanced treatment of sewage, has become the only way to solve the problem.
研究开发经济、高效的污水深度处理工艺对于消减污染物总量，改善水环境，营造良好的水环境及提高人们的生活质量，具有迫切的现实意义。深度处理一般采用微絮凝过滤或混凝沉淀过滤工艺等，进一步去除二级出水的主要污染物，而投加的絮凝剂是微絮凝过滤或混凝沉淀过滤工艺的主要运行成本，现有的投加系统只是根据进水流量和浊度来确定絮凝剂的投加量，然而投加絮凝剂进行过滤除了去除浊度外，还对总磷(TP)和固体悬浮物(SS)具有很好的去除效果，而TP和SS是污水厂二级出水中污水综合排放标准一级标准A标准的不能达标的最重要指标，并且很不稳定，这样投加絮凝剂过少出水不能达到标准，絮凝剂投加过量不仅会浪费，并且会产生大量的污泥。因此建立基于TP、SS和水量变化的自动加药系统具有重要的现实意义。Research and development of economical and efficient sewage advanced treatment technology has urgent practical significance for reducing the total amount of pollutants, improving the water environment, creating a good water environment and improving people's quality of life. Advanced treatment generally adopts micro-flocculation filtration or coagulation-sedimentation filtration process to further remove the main pollutants in the secondary effluent, and the flocculant added is the main operating cost of micro-flocculation filtration or coagulation-sedimentation filtration process. The addition system only determines the dosage of flocculant according to the influent flow rate and turbidity. However, adding flocculant for filtration not only removes turbidity, but also has a good effect on total phosphorus (TP) and suspended solids (SS). Removal effect, and TP and SS are the most important indicators that cannot meet the standard A standard of the comprehensive discharge standard of sewage in the secondary effluent water of the sewage plant, and are very unstable. In this way, too little flocculant is added and the effluent cannot meet the standard. The flocculant Dosing too much will not only waste, but also generate a lot of sludge. Therefore, it is of great practical significance to establish an automatic dosing system based on TP, SS and water volume changes.
另外，随着社会的迅速发展，污水处理厂逐渐普及使用在线监测仪代替人工来检测出水主要指标，这样购买的昂贵的在线监测仪就仅仅作为在线监测系统，并没有考虑到用于其他用途。In addition, with the rapid development of society, sewage treatment plants have gradually popularized the use of on-line monitors instead of manual labor to detect the main indicators of water. The expensive online monitors purchased in this way are only used as online monitoring systems, and are not considered for other purposes.

以江苏某污水处理厂为例，该污水处理厂提标改造，应用微絮凝-砂滤技术作为深度处理工艺，使出水由污水排放标准一级B提高到一级A，采用聚合氯化铝(PAC)作为絮凝剂。在使用过程中，首先设定最佳加药量ΔXPAC，通过现场长期大量数据得出k＝1、L＝7.18、a＝0.995、b＝0.058，进水流量Q大约为4166.67m3/h，一级A标准的TP浓度为0.5mg/L，SS浓度为10mg/L，最后得出XPAC值。Taking a sewage treatment plant in Jiangsu as an example, the sewage treatment plant was upgraded and transformed, using micro-flocculation-sand filtration technology as an advanced treatment process, so that the effluent was raised from the first-level B of the sewage discharge standard to the first-level A, and polyaluminum chloride ( PAC) as a flocculant. In the process of use, first set the optimal dosing amount ΔX PAC , and obtain k=1, L=7.18, a=0.995, b=0.058 through a large amount of long-term field data, and the influent flow Q is about 4166.67m 3 /h , the TP concentration of the primary A standard is 0.5mg/L, the SS concentration is 10mg/L, and finally the X PAC value is obtained.
