新海地区的河道是连云港市的景观水域。主要河道为蔷薇河,龙尾河,西盐河,大浦河和临洪河。蔷薇河不仅是新海地区的惟一饮用水源,而且是主要的工业和农业用水水源。近年来,由于大量工业污水和生活污水的排入,使得水域功能退化。新海地区的水环境严重恶化。目前,对城市污水的处理主要采用活性污泥法即兴建城市二级污水处理厂。无疑,兴建城市二级污水处理厂是处理城市污水比较成熟的方法,但是,这一方法并不适用于新海地区, 因为, 最终流入大浦河的污水其 B O D 年平均浓度为484 mg/l,它已接近二级污水处理厂的出水水质(30 mg/l) ,另一个原因,城市二级污水处理厂的建设和运行费用太高。通过对新海地区现有河道和临洪河滩地的实地考察,本文指出,利用临洪河滩地构建污水生态工程是处理新海地区污水行之有效的方法。
