Purification effect for swine wastewater with attached culture of microalgae
The purification effect of swine wastewater treated by Scendesmus dimorphus and Chlorella pyrenoidosa with attached culture was investigated in this study. It was shown that the 2 strains could grow well in swine wastewater and the biomass of Scendesmus dimorphus and Chlorella pyrenoidosa reached 6. 26 and 6. 08 g·m-2·d-1 , respective-ly. Meanwhile, the lipid content in the 2 strains was 34. 6% and 31. 4%, respectively, which was comparable with those cultivated in BG11 medium. Notably, attached culture of Scendesmus dimorphus and Chlorella pyrenoidosa could treat swine wastewater efficiently. The removal efficiency of ammonia nitrogen (NH3-N), total phosphorus (TP) and COD was 96. 59%, 74. 52% and 72. 47%, respectively, by Scendesmus dimorphus and 94. 90%, 73. 55% and 71. 40%, respectively, by Chlorella pyrenoidosa. Based on the results, a process combining algae-based wastewater treatment with attached cultivation and biodiesel production was proposed to treat swine wastewater.
