高难度废水处理技术与成套设备
物理法包括沉淀、过滤、吸附、萃取等,不改变污染物的化学形式。其设备简单、运行费用低、工艺成熟,主要用于去除水中难溶解的大颗粒污染物,为污水一级处理的首选技术。
Physical methods include sedimentation, filtration, adsorption, extraction, and so on, without changing the chemical form of pollutants. The equipment is simple, the operation cost is low, and the process is mature. It is mainly used for removing the large particles of refractory pollutants in the water. It is the preferred technology for the primary treatment of sewage.
多年来,科学家利用水体自净及土壤自净的原理,开发出了各种利用自然微生物处理工业废水及城市污水的技术,集中分布于活性污泥法和生物膜法两大系列。 现行污水处理技术主要可分为物理法、化学法和生物法。
Over the years, scientists have developed various techniques for treating industrial wastewater and municipal wastewater using natural microorganisms based on the principles of water self-purification and soil self-purification, which are mainly distributed in two series: activated sludge process and biofilm process. Current sewage treatment technologies can be divided into physical, chemical and biological methods.

化学法包括絮凝沉淀和化学氧化,改变污染物的存在形式,主要用于去除溶解于水中的小颗粒,通过电性改变、交联架桥等形式,使之成为大的颗粒沉淀分离出来。大量用于废水的预处理及深度处理。有高难度废水需要处理的单位,也可以到污水宝项目服务平台咨询具备类似污水处理经验的企业。
Chemical methods include flocculating precipitation and chemical oxidation, changing the existing form of pollutants, mainly used to remove small particles dissolved in water, through electrical changes, cross-linking bridges and other forms, so that it becomes a large particle precipitation separation. It is widely used for pretreatment and deep treatment of waste water. There are high-difficulty waste water need to be treated units, but also to the Sewage Treasure Project Service Platform consulting with similar sewage treatment experience of enterprises.
生物法是利用大自然处理废水的原始形式,利用微生物代谢来达到水资源净化的目的。微生物代谢环境存在好氧、厌氧、兼氧三种类型,由此也衍生了好氧、厌氧的处理方法。生物法主要用于污水的二级处理或高级处理,是目前污水处理的主要形式。
Biological method is the original form of using nature to treat wastewater, using microbial metabolism to achieve the purpose of water purification. There are three types of microbial metabolic environment: aerobic, anaerobic and facultative, which also derive aerobic and anaerobic treatment methods. Biological method is mainly used for the two stage treatment or advanced treatment of sewage, and is the main form of sewage treatment at present.
电子絮凝系统主要包括:电子絮凝器、离心澄清反应器、多介质过滤系统、控制系统等.
The electronic flocculation system mainly includes: electronic flocculator, centrifugal clarification reactor, multi-media filtration system, control system and so on.
