摘要
简述了沸石生物联合吸附再生工艺(ZCS工艺)的工艺原理,选取了影响沸石生物联合吸附再生工艺污水处理效果的影响因素,通过正交实验,优化了工艺的运行参数。在优化结果为泥龄(SRT)40 d、沸石投加量16.8 g/L、外回流比(R)1、内回流比(r)1、A池碳源投加比(m)0、吸附池溶解氧(DO吸)1 mg/L和O池溶解氧(DOO)2 mg/L的条件下稳定运行后,出水水质达到《城镇污水处理厂污染物排放标准》(GB18918-2002)中一级B标准的要求。
The principle of zeolite enhanced contact-adsorption regeneration-stabilization process （ZCS process） was briefly stated in the paper, and then the effects of different factors on long-term treatment efficiency of ZCS Process were studied according to the orthogonal experiments. The results of parameter optimization were： SRT of 40 d, zeolite powder dose of 16.8 g/L, R of 1, r of 1, m of 0, DOa of 1 mg/L and DOo of 2 mg/L. Under the optimal conditions, the concentrations of ammonia and TN in effluent could meet grade B of the first level in ＂Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant of China （GB18918-2002） ＂.
