TECHNOLOGY FOCUS - BIOLOGY - Preferred Method: In the step (i), the mass ratio of sodium hydroxide added into streptomycin bacteria slag, is 0.09. In the step (iii), the C/N ratio in the regulating tank, is 22:1. In the step (iv), the inner pH of the regulating tank, is 7.1.    TECHNOLOGY FOCUS - INSTRUMENTATION AND TESTING - Preferred Components: The device comprises the second online water quality monitoring system which is connected to the computer. The third online water quality monitoring system is connected to the ORP probe, the second temperature probe and the second pH probe. The ORP probe, second temperature probe and the second pH probe are connected to the inner side of the ASBR. The other end of the online water quality monitor system is connected to the computer. The inner side of the pre-reaction tank, regulating tank and ASBR are set with the first stirring paddle, second stirring paddle and the third stirring paddle. The first stirring paddle, second stirring paddle and third stirring paddle are connected to the PLC automatic control system of the through the first electric stirrer, second electric stirrer and third electric stirrer. The PLC automatic control system is connected to the pre-reaction tank. The inner part of the ASBR is connected to the PLC automatic control system by the first heating rod and the second heating rod which are in turn connected to each other. The regulating tank is connected to the online water quality rapid detection system. The other end of the online water quality rapid detection system is connected to the computer. The regulating tank is set with the straw fermentation tank. The lower end of the straw fermentation tank is connected to the regulating tank by the carbon source adding pump. The carbon source dosing pump is connected to the PLC automatic control system. The lower end of the regulating tank is set with two pieces of pipelines connected to the acid dosing pump and the alkali pump. The acid dosing pump is connected to the acid tank. The alkali tank is connected to the PLC automatic control system by the acid dosing pump and alkali pump. The right upper side of the ASBR is set with an air outlet passing through a water sealing device provided with the airbag.
