4) and (3) repeating the steps 2) and 3) until the effluent quality reaches more than 80% of the total nitrogen removal rate, and finishing the starting setting.
Then, the method for testing the purifying effect of the microorganism water quality purifying filter tank on the black and odorous water body comprises the following steps:
the device of the example 1 and the device of the comparative examples 1-2 are injected with simulated wastewater with the total nitrogen concentration of 10mg/L, the device is operated in an intermittent water inlet and outlet mode, the hydraulic retention time is 24h, the effluent of the reactor is taken every day to detect the nitrogen, phosphorus and COD of the effluent, and the average treatment effect in the experiment of 30 days is shown in the following table 1, wherein 60 percent of detection samples in the test of the example 1 frequently reach the IV-class water quality standard of surface water.
TABLE 1
Total phosphorus removal% Total nitrogen removal/%) COD removal Rate/%) SS removal rate/%)
Example 1 93 62 81 99％
Comparative example 1 91 37 36 95％
Comparative example 2 34 16 60 82％
The comparative example 1 lacks the bandage type filler, which causes the sludge concentration in the aeration aerobic zone to be obviously reduced, thereby causing the COD and ammonia nitrogen removal efficiency to be reduced, the consumption speed of the dissolved oxygen in water to be reduced, and the anaerobic environment of the anaerobic zone to be not ensured, therefore, the denitrification effect is reduced, thereby causing the total nitrogen removal efficiency to be reduced.
The lack of anaerobic filler in the comparative example 2 causes the enrichment effect of denitrifying bacteria in the anaerobic zone to be poor, and the activity of the denitrifying bacteria is greatly different compared with that in the example 1, so that the total nitrogen removal rate is low. And because substances such as calcium carbonate and the like are simultaneously added into the anaerobic filler, the device can remove phosphorus, and the phosphorus removal capability is correspondingly reduced after the anaerobic filler is lacked in the comparative example 2. Meanwhile, comparative example 2 also lacks the filtering effect of the filler, so that the SS is filtered by only three separators, and the removal rate of the SS is correspondingly reduced.
Test example 2
The starting process of the microbial water purification canister was the same as in test example 1.
The method for testing the purifying effect of the microorganism water quality purifying filter tank on the black and odorous water body comprises the following steps:
the simulated wastewater with the total nitrogen concentration of 40mg/L is injected into the device of the example 1 and the devices of the comparative examples 1 and 2, the device is operated in an intermittent water inlet and outlet mode, the hydraulic retention time is 24 hours, the effluent water of the reactor is taken every day to detect the nitrogen, the phosphorus and the COD of the effluent water, and the average treatment effect in the experiment of 30 days is shown in the following table 2.
