背景技术 Background technique
化工污水一直是污水处理领域的难点，污水中污染物浓度高、毒性大，对水处理微生物具有毒害和抑制作用，很多技术工艺难以达标，即使有少量的技术手段达标，但处理成本较高。 Chemical sewage has always been a difficult point in the field of sewage treatment. The concentration of pollutants in sewage is high and the toxicity is high, which has poisonous and inhibitory effects on water treatment microorganisms. Many technical processes are difficult to meet the standards. Even if a small number of technical means meet the standards, the treatment costs are high.
废水化学处理法是通过化学反应和传质作用来分离、去除废水中呈溶解、胶体状态的污染物或将其转化为无害物质的废水处理法。以投加药剂产生化学反应为基础的处理单元有混凝、中和、氧化还原等；以传质作用为基础的处理单元有萃取、汽提、吹脱、吸附、离子交换以及电渗吸和反渗透等。有废水臭氧化处理法、废水电解处理法、废水化学沉淀处理法、废水混凝处理法、废水氧化处理法、废水中和处理法等。与生物处理法相比，能较迅速、有效地去除更多的污染物，可作为生物处理后的三级处理措施。此法还具有设备容易操作、 Chemical wastewater treatment is a wastewater treatment method that separates and removes dissolved and colloidal pollutants in wastewater or converts them into harmless substances through chemical reactions and mass transfer. Treatment units based on chemical reactions generated by dosing agents include coagulation, neutralization, redox, etc.; treatment units based on mass transfer include extraction, stripping, stripping, adsorption, ion exchange, and electroosmotic absorption and reverse osmosis etc. There are wastewater ozonation treatment method, wastewater electrolysis treatment method, wastewater chemical precipitation treatment method, wastewater coagulation treatment method, wastewater oxidation treatment method, wastewater neutralization treatment method, etc. Compared with biological treatment, it can remove more pollutants more quickly and effectively, and can be used as a tertiary treatment measure after biological treatment. This method also has the advantages of easy operation of equipment,
容易实现自动检测和控制、便于回收利用等优点。化学处理法能有效地去除废水中多种剧毒和高毒污染物。废水处理类型主要包括1、废水臭氧化处理法是用臭氧作氧化剂对废水进行净化和消毒处理的方法。用此法处理废水所使用的是含低浓度臭氧的空气或氧气。臭氧是一种极不稳定、易分解的强氧化剂，需现场制造，工艺设施主要由臭氧发生器和气水接触设备组成。这种方法主要用于：水的消毒，去除水中酚、氰等污染物质，水的脱色，水中铁、锰等金属离子的去除，异味和臭味的去除等。主要优点是反应迅速、流程简单、无二次污染。在环境保护和化工等方面广泛应用。2、废水电解处理法，是应用电解的基本原理，使废水中有害物质通过电解转化成为无害物质以实现净化的方法。废水电解处理包括电极表面电化学作用、间接氧化和间接还原、电浮选和电絮凝等过程，分别以不同的作用去除废水中的污染物。其主要优点：①使用低压直流电源，不必大量耗费化学药剂；②在常温常压下操作，管理简便；③如废水中污染物浓度发生变化，可以通过调整电压和电流的方法，保证出水水质稳定；④处理装置占地面积不大。但在处理大量废水时电耗和电极金属的消耗量较大，分离的沉淀物不易处理利用，主要用于含铬废水和含氰废水的处理。3、废水化学沉淀处理法，是通过向废水中投加可溶性化学药剂，使之与其中呈离子状态的无机污染物起化学反应，生成不溶于或难溶于水的化合物沉淀析出，从而使废水净化的方法。投入废水中的化学药剂称为沉淀剂，常用的有石灰、硫化物和钡盐等。根据沉淀剂的不同，可分为：①氢氧化物沉淀法，即中和沉淀法，是从废水中除去重金属有效而经济的方法；②硫化物沉淀法，能更有效地处理含金属废水，特别是经氢氧化物沉淀法处理仍不能达到排放标准的含汞、含镉废水；③钡盐沉淀法，常用于电镀含铬废水的处理。化学沉淀法是一种传统的水处理方法，广泛用于水质处理中的软化过程，也常用于工业废水处理，以去除重金属和氰化物。上述方法均采用的化学处理方法，处理的过程中需要大量的化学反应物质，在处理了污水的过程中，又产生了其他的污染问题，不能够彻底达到污水的目的，还要浪费大量的化学物质，浪费能源。 It is easy to realize automatic detection and control, easy to recycle and so on. Chemical treatment can effectively remove a variety of highly toxic and highly toxic pollutants in wastewater. The types of wastewater treatment mainly include 1. Wastewater ozonation treatment method is a method of purifying and disinfecting wastewater by using ozone as an oxidizing agent. What this method uses to treat wastewater is air or oxygen containing low concentrations of ozone. Ozone is an extremely unstable and easily decomposed strong oxidant, which needs to be manufactured on site. The process facilities are mainly composed of ozone generators and gas-water contact equipment. This method is mainly used for: disinfection of water, removal of pollutants such as phenol and cyanide in water, decolorization of water, removal of metal ions such as iron and manganese in water, removal of peculiar smell and odor, etc. The main advantages are rapid response, simple process and no secondary pollution. It is widely used in environmental protection and chemical industry. 2. Wastewater electrolysis treatment method is a method of applying the basic principle of electrolysis to convert harmful substances in wastewater into harmless substances through electrolysis to achieve purification. Wastewater electrolysis treatment includes electrode surface electrochemical action, indirect oxidation and indirect reduction, electroflotation and electroflocculation, etc., which remove pollutants in wastewater with different functions. Its main advantages: ①Using a low-voltage DC power supply, there is no need to consume a lot of chemicals; ②It is operated under normal temperature and pressure, and the management is simple; ③If the concentration of pollutants in the wastewater changes, the voltage and current can be adjusted to ensure the stability of the effluent water quality ; ④ The processing device occupies a small area. However, when treating a large amount of wastewater, the consumption of electricity and electrode metal is relatively large, and the separated sediment is not easy to process and utilize, and is mainly used for the treatment of chromium-containing wastewater and cyanide-containing wastewater. 3. The wastewater chemical precipitation treatment method is to add soluble chemicals to the wastewater to make it chemically react with the inorganic pollutants in the ionic state, and form insoluble or hardly soluble compounds to precipitate out, so that the wastewater method of purification. The chemicals put into the wastewater are called precipitants, and the commonly used ones are lime, sulfide and barium salt. According to different precipitants, it can be divided into: ① hydroxide precipitation method, that is, neutralization precipitation method, is an effective and economical method to remove heavy metals from wastewater; ② sulfide precipitation method, which can more effectively treat metal-containing wastewater, Especially the mercury-containing and cadmium-containing wastewater that cannot meet the discharge standards after the hydroxide precipitation method; ③The barium salt precipitation method is often used for the treatment of electroplating chromium-containing wastewater. Chemical precipitation is a traditional water treatment method, which is widely used in the softening process in water quality treatment, and is also commonly used in industrial wastewater treatment to remove heavy metals and cyanides. The chemical treatment methods used in the above methods require a large amount of chemical reaction substances in the process of treatment. In the process of sewage treatment, other pollution problems have occurred. The purpose of sewage cannot be completely achieved, and a large amount of chemical substances have to be wasted. matter, waste of energy.
因此，通过对污水处理器合理的结构设计，达到出水水质好、经济实用的效果是本实用新型需要解决的问题。 Therefore, it is a problem to be solved by the utility model to achieve good effluent quality, economical and practical effects through reasonable structural design of the sewage processor.
