摘要:
针对钢铁企业平流沉淀池、化学除油器等传统浊环水处理系统存在的水质不达标、提升环节多、排泥不顺畅、药剂投加量高等问题，设计了一种用于钢铁企业的承压式浊环水处理系统。通过螺旋中心筒等结构提高混合效果，促进原水中钢渣颗粒物絮团的快速形成；利用负压喷射结构，使污泥无动力循环，增大絮团粒径，提高沉淀效率；利用封闭承压的运行环境，减少提升环节，提高排泥顺畅度，同时保持周边环境的整洁度；借助CFD流体力学分析软件模拟系统结构内部的流态变化，结合工程试验验证真实水源的处理效果。结果表明，承压式浊环水处理设备的实际运行效果达到了预期目标。
Abstract:
There are many problems in traditional turbid circulating water treatment system (such as horizontal sedimentation tank and chemical oil removal device) in steel enterprises, such as water quality not up to discharge standard, too much lifting, inconvenience of sludge discharge and high dosage of chemicals. A pressurized turbid circulating water treatment system was thus designed to solve these problems. Spiral center cylinder was applied to enhance the mixing and accelerate the formation of steel slag particle flocs in raw water. The negative pressure jet structure realized the sludge circulation without energy input, increased the particle size of the floc and improved the precipitation efficiency. The close pressurized operating environment was applied to reduce the lifting links, improve the efficiency of sludge discharge, and maintain the cleanliness of the surrounding environment. Computational fluid dynamics (CFD) software was employed to simulate the flow regime change inside the system, and the treatment performance of real water sources was verified by engineering tests, which indicated that the actual operation of the system reached the expected goal.
