Artificial crystal processing plant wastewater treatment flocculation process should be used artificial crystal processing plant wastewater treatment which flocculation process should be used artificial crystal in the decoration industry has made a significant contribution, not only that, nowadays artificial crystal gradually make up the natural Crystal's inherent deficiencies, it also makes the current crystal processing industry Peng Peng Sheng. However, due to the cumbersome process of artificial crystal processing and the use of a large amount of chemical materials, a large amount of processing wastewater is generated. So now also for the treatment, the treatment method commonly used traditional physical method, mainly because this method can not only do the zero discharge of crystal processing wastewater, is also expected to achieve recycling of waste water. However, the treatment of such wastewater is sometimes not so smooth, just take a recent crystal processing plant wastewater treatment is good, the details are as follows. Crystal processing plant crystal wash Beads waste water treatment, the centrifugal pump to the surface of the reaction tank to float a layer of white floating objects, physical and chemical treatment, by adding sodium hydroxide, polyaluminum chloride, polyacrylamide, to form Part alum flower. However, there are also some small floating like mortar, can not always precipitate, but floating on. Finally, the surface area of ​​the coagulation tank is slowed down by the coagulation floating material. Moreover, the water in the sedimentation tank has many suspended particles with small particles and can not precipitate and seriously affect the subsequent biochemical treatment. How to solve this kind of problem? If the past has been normal, the recent case of such a situation, it may be the raw water quality changes, it is estimated organic matter increased. Proposed to extend the sedimentation tank hydraulic retention time, the appropriate reduction of centrifugal pump flow (through the return valve adjustment), but also increased the coagulation time, the other should pay attention to the sedimentation of the PH value, such as the simple use of coagulation treatment will have a major impact Coagulation of the various factors, coagulant corresponding to the best coagulation effect of the pH value, the use of PAC, then the best precipitation PH is 7--9. General coagulation requirements of organic matter in the water (soluble), some relatively stable latex can not be too much. You can determine the best coagulation conditions in a lab test. Observed under the water floating objects have bubbles, bubbles have a physical method to break the bubble (ultrasound).
