Study on the Integrated Vortex-Grid Clarification Process and Its Application
Based on Micro-vortex coagulation and Hazen theory,the process of integrated vortex grid clarification bears four characteristics. Firstly,there are a lot of micro-whirling reactors whose surfaces hole rate is designed by the raw water quality in the first and second flocculation zone. Then,an inclined-tube in the precipitate zone is installed. Thirdly,a sludge concentration zone in the tank is also equipped. Lastly,by applying the low return or non-return technologies and changing some inner structure which will reduce the total energy cost. We have not only achieved a more efficient use of the cubage of the reactors,but also reduced the total energy consumption. The paper argues that in comparison to other clarification technology,the Micro-vortex clarification process deserves wide application for its various advantages,such as a higher coagulation efficiency,a shorter reactivity time,a better quality of finished water,a stronger adaptive capability,a more convenient construction and the like.
