Abstract: This article continuous loop reactor outside the optimum conditions of pig manure wastewater. Outside the continuous type circulates the reactor experiment use intermittence type reactor single factor analytic method, through change response each technological conditions (for example response initial density, reaction temperature, vaccination sludge quantity, response initial PH), thus discovers the active sludge processing excrement water best response technological conditions. The experimental study found that only change when the initial reaction concentration (ie the initial COD) and other reaction conditions remaining unchanged, we can see the initial COD was 4000mg / L around the reaction rate and gas production is the best; when the temperature changes , the initial COD was 4000mg / L and the other the same reaction conditions, the reaction rate at 35 ℃ is the fastest; for changing the PH of the experiment found that when the initial reaction of PH 7.0 or so (that is, when neutral ) the best reaction conditions. These conditions in a continuous loop reactor Outsider experiment, methane gas to civilian requirements, and reduced chemical oxygen demand of sewage discharge requirements.
