摘　　要：比较了不同预处理方法对养猪沼液的灭虫效果和后期微藻养殖的影响,拟优选出较佳的预处理办法。结果表明,养猪沼液在开放环境中放置一定时间后,易出现原生动物、微型后生动物和其他无脊椎动物,而对微藻生长影响较为严重的主要是原生动物和微型后生动物;用40mg/L的漂白粉处理可以基本杀灭养猪沼液中的食藻害虫,处理后的养猪沼液只需放置4d后就可以接种、培养微藻;这种预处理方法成本相对较低,每吨养猪沼液的处理成本仅约为0.050 0元;这种预处理方法操作简单,而且对养猪沼液中的营养元素破坏较少,为利用养猪沼液实现规模化微藻养殖解决了一个棘手的问题。It is of great significance for controlling algae-eating pests in the process of microalgae cultivation. In this paper, different pretreatment methods were performed before microalgae cultivation in swine biogas slurry, the in- secticidal effect of different pretreatment methods as well as their influence on microalgae cultivation was thoroughly compared so as to select the best pretreatment method. Results showed that protozoa, metazoan and other inverte- brates appeared after biogas slurry placed in open environment for a certain period, protozoa and metazoan had a great influence on the growth of microalgae. After applying 40 mg/L of bleaching powder, algae-eating pests in swine biogas slurry were basically killed,and inoculated of microalgae could performed after only 4 days. The cost of bleaching pow- der method was relatively low,the per ton pretreatment cost of only about 0. 050 0 yuan. This method was easy to op- erate,and nutrient in swine biogas slurry was little damaged. This paper had important guiding significance for achie- ving the large-scale culture of microalgae in swine biogas slurry.
