  the effluent
Under deficient influent alkalinity, when compared to OAA, the AAA process improved treatment efficiency and effluent quality with NH4+-N in the effluent below the detection limit.
      
Applying the control strategy water quality of the effluent could stably meet the national first discharge standard during experiment of 10 months.
      
Even at low temperature (t = 13°C), chemical oxygen demand (COD) and total nitrogen (TN) in the effluent were under 50 and 5 mg/L, respectively.
      
However, there was not much difference between these two kinds of sludge in terms of the total phosphorus uptake quantity and the effluent quality.
      
Hence, the concentrations of some small metabolites, such as nonylphenol (NP), nonylphenol monoethoxylate (NP1EO), and nonylphenol diethoxylate (NP2EO) were elevated in the effluent.

The study on characteristics of thermomechanial pulping effluents indicates that the contents of COD and total carbohydrates in this effluents are more than 5000mg/1 and 3000mg/1 respectively and that hexose are dominant constituents and that free sugars are present in significant amounts. The contents of total solid and total volatile solid are similar to those in the composition of a machine effluent from a strawboard mill, while the solid content in TMP white water is rather low. A high percentage reduction in COD (about 80 percent) was obtained in an anaerobic flow system with a partial recycle flow under the conditions of an organic loading of 6-7kg/m3d in terms of COD, a retention time of 24 hours, and a temperature of 34-36°C. The content of CH4 in the biogas is more than 80%.
