| 1、化工废水成分复杂，反应原料常为溶剂类物质或环状结构的化合物，增加了废水的处理难度; 1. Chemical wastewater is complex in composition, and the reactants are usually solvents or ring-shaped compounds, which increase the difficulty of wastewater treatment. 2、该废水中含有大量污染物物质，主要是由于原料反应不完全和原料或生产中使用大量溶剂造成的； 2. The wastewater contains a lot of pollutants, which are mainly caused by incomplete reactions of raw materials and the use of a large number of solvents in production. 3、有毒有害物质多，精细化工废水中有许多有机污染物对微生物是有毒有害的，如卤素化合物、硝基化合物、具有杀菌作用的分散剂或表面活性剂等; 3. There are many toxic and harmful substances. Many organic pollutants in fine chemical wastewater are toxic and harmful to microorganisms, such as halogen compounds, nitro compounds, dispersants or surfactants with bactericidal effect, etc. 4、生物难降解物质多，B比C低，可生化性差。 4. There are many biodegradable substances, B is lower than C, and its biodegradability is poor. 废水性质 Properties of wastewater 化工产品生产过程中产生的废水表现为：排放量大、毒性大、有机物浓度高、含盐量高、色度高、难降解化合物含量高、治理难度大,但同时废水中也含有许多可利用的资源，而膜技术作为高新技术在化工领域的生产加工、节能降耗和清洁生产等方面发挥着重要。 Wastewater produced in the production of chemical products is characterized by large discharge, high toxicity, high concentration of organic matter, high salinity, high chroma, high content of refractory compounds and great difficulty in treatment. At the same time, wastewater also contains many available resources. Membrane technology, as a high-tech, can save energy in the production and processing of chemical industry. Consumption reduction and clean production play an important role. |
