工艺在矿区污水治理中的应用

为了进一步改善矿区地表水环境质量,针对污水排放特点,研究确定耐冲击负荷强的污水处理技术,提出了采用CAST工艺处理以煤矿生活污水为主,同时收集处理达标排放的工业废水,并采取在主反应区投加组合填料等方式强化处理效果。结果表明:CAST工艺对于小型污水处理厂建设,投资和运转费用低,对原水水质水量的变化有较强的适应能力,出水水质好,污泥量少且易于处置,处理后的水可做杂用水和工业用水,提高了污水综合利用率。 In order to improve the environment of mining area,provide CAST bassed on sewage discharge features.Industrial wastewater which is up to standard and most coal mine sewage are disposed by CAST process.Adding combined reagent in main reaction area is the best way to satisfy the disposal requirement.The results indicate that this process can reduce the consumption of small scale sewage treatment plant,have a better adaptive ability to change of effluent quality and quantity.The effluent contains little sludge,with good water quality which can be used in industry,and the benefits are obvious
