摘要:
砂水分离器是污水处理厂沉砂池的重要组成部分，直接影响除砂效果。以华北地区某污水处理厂为研究对象，通过数学模拟与生产性试验，对比分析了在原有砂水分离器上增设顶托式和侧翼式两类辅助沉淀模块的除砂强化效果。结果表明，顶托式和侧翼式改良除砂效率相当，除砂效率均较改造前大幅提升，在生产性试验条件下，由改造前平均为48.51%提升至改良后平均为89.13%。连续9个月的生产运行出砂量相应提升146%。通过不同粒径除砂效率分析可知，顶托式改良较侧翼式改良对144 ?m以下细小砂砾去除能力更佳，去除率提升约20个百分点；从经济效益分析，改造成本为原始砂水分离器的30%～50%，基本不增加运维成本。
Abstract:
The grit-water separator is a crucial component of grit chamber in a sewage treatment plant, directly influencing the efficiency of sand removal. A research subject was implemented in a municipal sewage treatment plant in North China. Mathematical simulation and productive trials were utilized to compare and analyze the enhanced sand removal effects of adding top-support and side-wing sedimentation modules to the original grit-water separator. The results showed that the top-support and side-wing modifications significantly improved more sand removal efficiency. Under productive trial conditions, the average sand removal efficiency increased from the previous 48.51% to an improved average of 89.13%. Over nine consecutive months of operation, the sand production volume increased by 146%. It revealed that the top-support modification outperformed the side-wing modification in removing fine sand particles below 144 m, with about 20 percentage points higher removal rate by analyzing of sand removal efficiency for different particle sizes. From an economic perspective, the modification costs were approximately 30%-50% of the original grit-water separator’s cost, with minimal additional operation and maintenance expenses.
