Main features of integrated sewage treatment equipment
In addition to containing a large amount of phosphate, zinc ions, acid-base substances and organic matter, wastewater sometimes also contains a certain amount of nickel ions, copper ions or lead ions and other pollutants such as heavy metals and surfactants depending on the production process. Complex and difficult to handle. At present, the treatment of this type of wastewater is mainly based on physical and chemical methods, that is, according to different treatment objects and treatment purposes, combined processes such as dispersed precipitation, air flotation, filtration, activated carbon adsorption, and membrane separation are used. In process selection, it is necessary to consider reducing process links, reducing project investment and operation difficulty, and also considering the mutual interference between different pollution factors to reduce the treatment effect. Phosphate and zinc ions are the main pollution factors of pickling phosphate wastewater, and phosphate is also a difficult point in the treatment of this type of wastewater.
Sewage treatment equipment process specification-design and requirements
1. Adopt advanced and reliable technology, high degree of automation, less land occupation, stable mud discharge and good effect;
2. Humanized design, practicality, aesthetics and sense of the times. Adopt advanced technology, stable and reliable operation, easy maintenance, simple operation, organically combine advancement and reliability, ensure that sewage treatment reaches the design goal, and reduce project investment and operating costs as much as possible. Use less technology, sewage treatment facilities must Efficient, energy-saving, economical and durable, and equipment should be reasonable to ensure the normal and stable operation of the system.
3. Low investment, convenient operation, low operating cost, economical and efficient; According to the actual situation of the project and the characteristics of sewage, choose a treatment process with mature technology, reasonable investment, easy operation, convenient management, stable and reliable operation, and low treatment cost.
