滨州海水池塘养殖梯度利用水质状况分析

Analysis on water quality of gradient utilization in Binzhou seawater pond culture

为加强全市海水养殖水排放监管,凝练滨州海水养殖梯度利用模式,并为全面实现海水养殖尾水达标排放及建立渤海生态整治滨州渔业样板提供基础数据,对滨州市几家重点海水池塘养殖企业的进水渠、南美白对虾养殖池以及卤虫池进行调查和监测。结果显示:随着海水池塘梯度养殖的进行,pH值没有明显变化,悬浮物、活性磷酸盐、化学需氧量总体呈逐渐增加趋势,无机氮呈逐渐减少趋势。研究认为,海水池塘养殖梯度利用模式有利于大幅降低无机氮含量,同时缓解磷缺乏的现状。

In order to strengthen the regulation of the city's mariculture discharge,concise Binzhou mariculture gradient utilization mode,fully realize the mariculture tail water discharge standards and provide basic date for establishing Binzhou fishery mode,water quality of the inlet channel,shrimp farming ponds and artemia ponds of several key marine pond aquaculture enterprises in Binzhou was investigated and analyzed. The results showed that with the progress of gradient culture, the pH value did not change significantly, and the suspended solids, reactive phosphate, chemical oxygen demand showed a gradually increasing trend. And inorganic nitrogen showed a gradually decreasing trend. It is believed that the gradient utilization mode of seawater pond culture is conducive to greatly reduce the content of inorganic nitrogen and alleviate the current situation of phosphorus deficiency.
