摘要
针对养猪废水中氮磷、有机物等浓度较高的特点,探讨了满足技术规范要求的处理水质标准的藻类生物处理工艺。通过正交试验,探讨了丝状藻对养猪废水的处理效果,得出最优的实验条件,并根据正交试验得出的最优条件,进行半连续的处理工艺,验证丝状藻对养猪废水的处理效果。结果表明,藻类对碳氮比低、氮磷含量偏高的养猪废水有很好的处理效果。
According to the characteristics of high concentration of nitrogen and phosphorus,organic matter in swine wastewater,the algae biological treatment technology which meet the requirements of technical specification was discussed.Through the design of orthogonal experiment,the effect of filamentous algae on the treatment of swine wastewater was studied,and the optimum conditions were obtained.According to the optimal conditions obtained by orthogonal experiment,the semi continuous treatment process was carried out to verify the effect of filamentous algae on the treatment of swine wastewater.The results showed that the algae had a good treatment effect on the low carbon and nitrogen ratio,high nitrogen and phosphorus content of swine wastewater.
