Basic conditions: Aerobic pool 5500F, ammonia nitrogen 100;  Anaerobic tank: 5000F, ammonia nitrogen 85, daily sewage treatment capacity of 3500F.

Ensure that the anaerobic tank SV30 at about 40%, stop the anaerobic tank in and out of water, anaerobic agent dosage of 200ppm, 200 grams of bacteria per cubic meter, with an effective volume of 7000 square calculation, one-time add 1400 kilograms of anaerobic agent, anaerobic agent one-time head after adding 800 kilograms of flour, urea 80 kilograms to the anaerobic tank every day,  Aerated for 2 hours a day, 1 hour in the morning and 1 hour in the evening (or 2 hours when the push flow is opened). After 7 days, gradient water intake is taken. The water intake for the first time is 10% of the total water volume of a biochemical system, and gradually increases by 10% of the total water volume every day.  

2, ensure that the aerobic pool SV30 at about 35%, stop the aerobic pool water in and out, aerobic agent dosage of 200ppm, 200 grams of bacteria per cubic meter, to calculate the effective volume of the aerobic pool 8000 square one-time add 1600 kilograms of aerobic agent, add 850 kilograms of flour to the aerobic pool every day, 85 kilograms of urea, aeration for more than 20 hours a day,  After 7 days of cultivation, the amount of water in and out of the anaerobic tank gradually increased, and the nutrients were halved after normal water in and out.
