1. Technical parameters (1) generally use a mechanical reaction, the reaction time was 15 minutes. Upflow velocity (2) contacting zone flotation chamber was 47mm / sec combination flotation device, after the separation of 0.46mm / sec. (3) a reflux ratio is generally 30%, treated water is 0.25-0.4m3 / hr. Sewage flow impact on the treatment effect. Affect the flow of sewage treatment effect can not be ignored. In the flotation machine is running must be guaranteed in each flotation tank water distribution uniformity, traffic changes mean changes in the amount of pollution flotation device, you need to adjust the dosage of medicine in order to achieve the best results. When the water flow is too large flotation device role flotation tank level flow speed, shorter residence time of floating floc separation unfavorable; the flow rate through the General Assembly flow turbulence caused by the separation zone is too large and cause bubbles floc combination broken. When excessive water should promptly adjust the height of the weir system to prevent sewage into the scum. CAF equipment, Heilongjiang flotation equipment, new environmental protection provided by Seoul Seoul Environmental Protection Equipment Co., Ltd. Weifang new. The new Environmental Protection Equipment Co., Ltd. Weifang Seoul (www.wfxiner.com) strong, credible, Weifang in Shandong sewage treatment equipment industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead the new Seoul into the brilliant green and you work for a better future!
