摘要
利用从市政污水中筛选的3株菌株制备成BOD5接种冻干粉剂,用于BOD5接种。实验确定了冻干粉接种菌剂最佳制备条件。以葡萄糖和谷氨酸配制的标准溶液（GGA）和实际废水为实验对象,完成了制得菌剂与传统接种液（土壤浸出液）及国外商业菌种Polyseed的性能对照。用接种菌剂接种测定GGA的测定结果均在180~230 mg/L,满足标准要求,接种菌剂、土壤浸出液和Polyseed的标准偏差分别为3.60、8.34、2.87 mg/L,测定实际废水的标准偏差分别为8.5、33.26、.0 mg/L。
Three strains screened from the municipal wastewater were used to make the BOD_5 inocula for BOD_5 test.The best conditions for making the freeze dry power(BOD_5 inocula) were studied.The characteristics of the BOD_5 inocula were compared by test on soil leaching solution and commercial Polyseed of GGA's and the actual wastewater's BOD_5 determinition.The standard deviation of inocula,soil leaching solution and polyseed was 3.60,8.34 and 2.87 mg/L respectively in GGA's experiment,and 8.5,33.2 and 6.0 mg/L in the test of actual wasterwater.
