背景技术Background technique
现有水处理工段投放聚合氯化铝PAC、聚丙烯酰PAM由人工完成，投药时溶解桶的水位和投药速度，操作人员很难做到准确一致。尤其是PAM投入过快会絮结成团，严重影响水处理质量。如果投加过量，易使悬浮的胶体颗粒处于稳定状态，不利于混凝沉淀；如果投加过少又达不到混凝的效果，也不利于沉淀。针对水处理人工投药导致水质量不稳定和公司对水处理设施自动化升级改造的需要，有必要设计出一种水处理定量投药装置。The injection of polyaluminum chloride PAC and polyacryloyl PAM in the existing water treatment section is done manually, and it is difficult for the operator to be accurate and consistent with the water level of the dissolution tank and the injection speed during the injection. In particular, if PAM is put in too quickly, it will flocculate into agglomerates, which will seriously affect the quality of water treatment. If you add too much, it will easily make the suspended colloidal particles in a stable state, which is not conducive to coagulation and sedimentation; if you add too little, the effect of coagulation cannot be achieved, and it is also not conducive to precipitation. In view of the instability of water quality caused by manual dosing of water treatment and the company's needs for automatic upgrading and transformation of water treatment facilities, it is necessary to design a water treatment quantitative dosing device.
