Through researching the mechanism of biological nitrification and denitrification and actual project application of the technology and related literature materials, the obtained results are as follows:(1) Anoxybiosis is effective to the removal of COD; after the anoxic process, BOD/COD of the outflow increases, it shows that the degradation ability of wastewater is improved; anoxybiosis is insensitive when shock loading of inflow wastewater varies greatly;(2) It is demonstrated by the operation of inoculation and cultivating that biofilm takes two weeks to succeed in cultivating on packings and the removal ratios of NH3-N and COD get 50% and 70% respectively, when gas-water ratio is 6:1, HRT is 7.3 hour, water temperature is above 15°C;(3) It is demonstrated that gas-water ratio, hydraulic loading, HRT, temperature, pH etc are important factors which influence the removal effect of pollutants, when the gas-water ratio is 6:1, hydraulic loading is about 0.38kgNH3-N/m~3.d, water temperature ranges from 15°C to 27°C, pH ranges from 7.5 to 8.0, the BIOFOR removal effect of pollutants is the best;(4) The operation indicated that, this technology has strong ability of nitrification and denitrification; it has extremely vital significance for reducing the water body eutrophication;(5) It is confirmed the feasibility and the usability of preanoxic-BIOFOR process to treat L-lactic acid production wastewater. The experiment indicated that the treatment effect of this technology is very good and also shows that the technology has many advantages, such as small volume, high treatment efficiency, good effluent quality and strong endurance to load variation, this technology is a new and economical wastewater treatment process.

The sludge settling characteristic is satisfying with SV varying from 22 to 30 and SVI varying from 58 to 80ml/g.The sludge bulking problem has been avoided successfully. The excess sludge can be thickened to 3%-4 %. The alkalinity remains equilibrious between the nitrification and denitrification in SBR-BAF system. The COD and TP loading of SBR are 2.08kgCOD/kgMLSS·d and 41.68gTP/kgMLSS·d, respectively. The NH4+-N loading of BAF is 1.16kgNH_4~+-N/m~3.d. The total HRT is about 10 hours which is only about half of suspended growth process for simultaneous phosphorous and nitrogen removal. Under the above mentioned high loadings and short HRT, the mean removal efficiency of COD, TP, NH4+-N, TN is 96%, 98%, 93%, and 84%, respectively. The mean effluent concentration of COD, TP, NH4+-N, TN, SS is 20mg/L, 0.23 mg/L, 3.24 mg/L, 7.68 mg/L, 5 mg/L respectively, which means every index can meet the first class of Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant.

After the coagulation and sedimentation in the jar test with ferric chloride, the residual COD in the supernatant was 9000 mg/L which was further oxidized by chloric acid or with Fenton method. The COD removal efficient increased with the increasing of the dosage of chloric acid from 0.5 ~ 100 g/L or the H2O2/Fe2+ from 5/2.5 ~ 50/25 g/L, and the economical dosage were suggested as chloric acid 50 g/L or the H2O2/Fe2+ 50/25 g/L which resulted in the residual COD of 400 and 3300 mg/L individually for 95 and 63 % COD removal percentages. Oxidation test showed that only 5 minutes was needed for 92 % COD removal in the case of chloric acid dosage 50 g/L.
