湄洲湾海域污水排海工程环境容量评价的研究

Assessment of environmental capacity for sewage discharge into Meizhou bay

介绍了福建某化工生产污水排海后对海湾污染程度预测的方法和过程,通过现场试验和理论分析计算,对湄洲湾海域利用海洋的自净能力和环境容量排海处置污水进行了研究,得到了污水排放后随着潮汐变化迁移的路线和浓度变化的规律.并以COD为指标对湄洲湾海域迁移扩散自净能力进行了综合评价,得到了排放口容许COD排放量及实际生产排放污水对环境影响程度的评价,以及海湾再能接纳排污总量的能力.

The method and process were discussed for predicting the degree of contamination caused by sewage discharge from a chemical factory in Fujian province into the Meizhou bay.Through the on -site experiment and theoretic analysis,the effect of sewage discharge into Meizhou bay,the maritime self-cleaning capacity and the environmental capacity and the route of sewage transference and the law governing the alteration of concentration with tides were established.Furthermore,a comprehensive assessment of the self-cleaning ability of sewage transference and diffusion in Meizhou bay enabled the establishment of permissible amout of COD.
