联邦德国Bad Rappenau市的CARIX水厂过滤器流出物浓度的研究

INVESTIGATION ON THE FILTER EFFLUENT CONCENTRATIONS AT THE BAD RAPPENAU CARIX PLANT

本文叙述了在联邦德国Bad Rappenau市的CARIX水厂四年多来的运行经验,以及产水中和再生液中的浓度变化情况。假如在整个产水周期中原水浓度固定不变,则硬度平均减少60%,硫酸盐减少91%,硝酸盐减少78%,重碳酸盐减少56%,但氯化物含量没有净减少。再生过程中,产水的二氧化碳的总消耗量为0.42 kg/m^3。

This paper describes treatment of drinking water experience for more 4 years at the Bad Rappenau CARIX plant, and development of concentrations in the product water and in the regenerant solution of filter, Assuming constant raw water concentrations over the entire service cycle the average elimination is 60% for total hardness, 91% for sulfate, 78% for nitrate, and 56% for bicarbonate, whereas there is no net reduction of chloride content. The consumption of carbon dioxide amounted to 0.42 kg/m^3 of product water.
