舟山市六横日产10×10~4 t海水淡化工程Ⅰ期采用溶解矿物质贝壳作为填料,用来矿化处理经反渗透后的海水,满足出水水质达到生活饮用水卫生标准的要求。贝壳填料布置呈上小下大的形式,结合由下向上的进水工艺,使得出水水质达到生活饮水卫生标准且工艺效果优于普通的石灰石填料。采用贝壳填料,每次补充584 t,可节省66.5万元,经济性十分明显。 Six Horizontal Nissan 10 × 10 ~ 4 t Desalination Project Phase Ⅰ The dissolved mineral shell is used as a filler to treat the seawater after reverse osmosis to meet the requirements of drinking water quality. The packing arrangement of the shell was in the form of small and large, combined with the water inflow process from bottom to top, which made the effluent water quality reach the sanitary standard of domestic drinking water and the process effect was better than ordinary limestone packing. The use of shell packing, each supplement 584 t, can save 665,000 yuan, the economy is very obvious.
