【摘要】 污水排海主要有岸边直排和深海排放两种方式 ,本文以深圳下沙海域为例 ,采用数值模拟的方法 ,对污水岸边排放和在 5 0 0m及 10 0 0m不同距离的深海排放进行了计算和分析 ,结果表明 ,在一般水动力条件下 ,污水排放距岸越远 ,对海水水质的影响越小 ,岸边直排对近岸海域影响最大。更多还原

【Abstract】 Two cases of sewage discharged into sea were commonly existed, coastal water discharges directly and deep water discharges. Computation and analysis were made for the two cases in Xiasha sea area of Shenzhen by the numerical simulation method. The scenarios of 500 m and 1000 m from the coast were considered for the deep water discharged. The results show that the effect on water quatity is lighter under condilion of longer distance from the coast than shorter.更多还原
