摘要
采用控制变量法,通过实验室模拟试验,测定不同EM投加量与曝气量组合条件下废水中COD Mn、TN、NH3-N、TP的质量浓度随处理时间的变化特征,探索EM投加量与曝气量对养殖废水净化效果的影响。结果表明:EM的最佳投加量为0.5×10-5(V原液/V废水),去除TN效果最佳的曝气量为0.5L/min;EM对养殖废水的净化处理效果尽管受到诸多因素的影响,但最直接的影响因素是投加量与曝气量。
Through laboratory simulation tests, the control variable method was used to measure the variation characteristics of CODMn, TN, NHa-N, and TP in wastewater under combined conditions of different EM dosage and aeration amounts with different treatment times, and to explore the influence of EM dosage and aeration amount on the purification of aquaculture wastewater. The test results show that the optimal dosage of EM was 0. 5× 10^-5 （VEM/Vwastewater）, and the optimal aeration quantity for removing TN was 0. 5 L/min. Although the purification effect of aquaculture wastewater using EM was influenced by many factors, the most direct influencing factors were the dosage and aeration amount.
