摘　　要：为了解二氯异氰尿酸钠消毒屠宰场的屠宰车间和待宰栏的最佳浓度和最佳作用时间以及对不同点位的消毒情况,试验采用活菌计数法,检测消毒前后微生物数量的差异,研究二氯异氰尿酸钠对屠宰场的屠宰车间和待宰栏的消毒效果。结果表明:从经济性考虑,屠宰车间选用有效氯浓度450 mg/L进行车间的日常消毒,消毒时控制喷洒量为200 mL/m2、消毒液作用时间保持15 min以上,烫毛池、外刮毛区、卸内脏区、开膛区、内刮毛区、劈半机地面、胴体检疫区地面、内脏清洗区台面、内脏清洗区水槽和内脏清洗区墙壁等均可达到消毒效果,放血槽、内脏清洗区、预清洗机等位置在喷洒量增加至500 mL/m^(2)时也达到了消毒效果。生猪待宰栏内二氯异氰尿酸钠的适用浓度考虑选用有效氯浓度200 mg/L,喷洒量为250 mL/m^(2),消毒液作用时间保持15 min以上可对栏内地面、墙面起到消毒效果。To determine the optimal concentration and optimal retention time of sodium dichloroisocyanurate in the slaughtering workshop and pig lairage of slaughterhouses,and the disinfection at different points,this experiment used the viable cell counting method to detect the difference in the number of microorganisms before and after disinfection and studied the disinfection effect of sodium dichloroisocyanurate in the workshop and pig lairage of slaughterhouse.The results show that,considering the cost⁃effectiveness,this experiment chose an effective chlorine concentration of 450 mg/L for disinfection of the slaughtering workshop.The spray volume was controlled at 200 mL/m^(2),and the disinfectant was kept in contact more than 15 minutes.Most areas were able to achieve the disinfection effect.The applicable concentration of sodium dichloroisocyanurate in the pig lairage is considered to be 200 mg/L of effective chlorine,with a spray volume of 250 ml/m^(2).Disinfection for more than 15 minutes can achieve an effect on the ground and walls of the pig lairage.
