With an in-depth understanding of the water environment treatment needs of industrial enterprises, Hezhong has launched zero-discharge solutions for high-salt wastewater in view of the special situation of industrial wastewater treatment in China and the complex and changeable specific situation of industrial water.
Adhering to the purpose of "mainstream technology, mature process", the program comprehensively understands the characteristics of water quality, pollutant composition and actual working conditions, and formulates the most suitable treatment process solutions for the complex and changeable water quality combination. With mature and perfect pilot test equipment and perfect data storage database analysis, the feasibility of the process is verified accurately, and the perfect process design is realised according to different water quality conditions, so as to ensure high standard and low miscellaneous salt rate, meet the demand of resource recycling, and realise the continuous and stable operation of the system. At the same time, pay attention to technical details, think about what customers think, multi-link consideration to help enterprises reduce the cost of water treatment, establish water/salt circular economic model, achieve cost optimisation.
Customised process design
The composition of industrial wastewater is complex, and the water quality and quantity fluctuate greatly. In order to ensure the output of high-quality resource-based crystalline salt, it is necessary to fully analyse the characteristics of water quality and customise the process design according to the water quality. The industrial wastewater contains salts, mainly salt and the nitrate different according to different water quality, salt nitrate than, and combined with such as COD, ammonia and other harmful ingredients, customise the zero discharge of the overall solution: pretreatment - deep processing - evaporation crystallisation, get high quality crystal salt products, product water recycle, ultimately achieve zero emissions.
Customized use of evaporative crystallization technology for wastewater zero discharge——mainly dependent on the salt-nitrate ratio of wastewater:
Design basis of evaporative crystallization technology
