Meanwhile, the same amount of chlorella and composite microbial inoculum is used for treating wastewater, then the concentration of organic Compounds (COD), the concentration of ammonia nitrogen, the concentration of Total Nitrogen (TN) and the concentration of phosphate after treatment are detected, and the COD removal rate, the ammonia nitrogen removal rate, the TN removal rate and the phosphate removal rate are calculated. The results are shown in Table 1.

The removal rate of pure algae has higher removal rate on ammonia nitrogen and total nitrogen in the wastewater in the first period and the second period, the removal rate of the ammonia nitrogen is up to 90 percent, the removal rate of the total nitrogen is up to 76 percent, but the long-acting property is poor, and the removal rate of the ammonia nitrogen is reduced to 21 percent from the third period; in a certain reaction time, the symbiotic system with the ratio of bacteria to algae of 1:3 has the best effect of removing the total nitrogen, ammonia and nitrogen in the sewage, the ammonia and nitrogen removal rate is maintained at about 85 percent, the total nitrogen removal rate is maintained at about 75 percent, and the system has long-acting property.
FIG. 3 is the average removal rate of ammonia nitrogen by different bacteria-algae ratios; FIG. 4 mean removal of total nitrogen for different algal comparisons.
As can be seen from FIGS. 3 and 4, the removal rates of ammonia nitrogen and total nitrogen show a trend of increasing first and then decreasing along with the decrease of the algae proportion in the system; when the ratio of bacteria to algae is 1:3, the average removal rate of the total nitrogen and ammonia nitrogen of the sewage by the symbiotic system is optimal, the average removal rate of the ammonia nitrogen is 85 percent, and the average removal rate of the total nitrogen is 80 percent.
