In order to research the relations of carbon sources to structure of PHAs, six kinds of PHAs sample were synthesized by activated sludge with six different carbon sources respectively in the aerobic-anaerobic-anoxic process. Their structures were determined by 〓HNMR、〓CNMR and GC-MS. When the carbon source was acetate, the unit composition of PHAs was 93. 91mol％ 3-hydroxybutanoic acid and 6. 09mol％ 3-hydroxypentanoic acid ; When the carbon source was propionate, the unit composition of PHAs was 28. 66mol％ HB, 63. 13mol％HV, 2. 55mol％ 2-methy-3-hydroxy-butanoic acid (2MHB) and 5. 66mol％ 2-methyl-3-hydroxypentanoic acid (2MHV); When the carbon source was 80％ butyrate and 20％ 1, 4-butanediol, the unit composition of PHAs was 65. 03mol％ HB, 28. 06mol％HV, 1. 91mol％2MHB, 2. 69mol％ 2MHV, 0.73mol％ 4-hydroxy butanoic acid (4HB), 0.78mol％ 4-methyl-3-hydroxy-pentanoic acid (4MHV), 0.80mol％ 3-hydroxyhexanoic acid ; When the carbon source was 20％ butyrate and 80％ 1, 4-butanediol, the unit composition of PHAs was 61. 39mol％ HB, 23. 01mol％HV, 4. 58mol％2MHB, 5. 97mol％ 2MHV, 0.91mol％ 4HB, 2. 37mol％ 4MHV, 1. 77mol％ HHx; When the carbon source was 60％ pentanoate and 40％glucose, the unit composition of PHAs was 41. 24mol％ HB, 58. 76mol％HV; When the carbon source was 60％ benzoate and 40％ glucose, the unit composition of PHAs was 65. 48mol％ HB and 34. 52mol％ HV.

Inhibition to activated sludge process by 2-naphthol was also investigated by Warburg respirometer to verify the conclusion drawn from Rank Cell respirometer test. 2-Naphthol in low concentration was biodegradable, hence resulted in the acceleration of respiration, while in higher concentration 2-naphthol would dramatically inhibit microorganisms respiration on account of high K〓 and electron density.

The sludge in SBMBR1 presented granular characteristics and settled very well. The sludge in SBMBR1was brown and the sludge flocs was smashed by the shear force due to high intensity of aeration. The sludge size decreased and the sludge flocs blended with water forming ropy solutions, and there was no distinguish interface between water and sludge. Low sludge age and high loading operation enabled the sludge in SBMBR1 keeping higher sludge activity and the MLVSS/MLSS ratio and SOUR values of SBMBR1 were higher than SBMBR2. Both in SBMBR1 and SBMBR2, there were large amount of zoogloea, bacillus, coryneform of bacteria, and pediococcus. However, in SBMBR1 there were also a lot of Protozoa like epistylis and etc. A certain amount of filamentous bacteria can also be found in SBMBR1. The biological species in SBMBR1 were much more abundant than that in SBMBR2.3. Membrane fouling on flat-sheets membrane was observed and analyzed with AFM, SEM and TEM. After the measurement of membrane surface EPS and membrane surface ETX analysis, the pollutants composition on the surface of flat-sheets membrane was calculated.

The present research situation about AB process in and out of our country was analyzed in this paper. In addition to a concentrated study of the factors affecting sedimentation performance of A-step activated sludge, the rule of microbe multiplication, yield of activated sludge in A-step and treatment of low-concentration sewage were also involved in this paper. The main conclusions are as follows:(1) The study on factors affecting sedimentation performance of A-step activated sludge shown that the inflow SS distinctly improve sedimentation performance of activated sludge, the less influent SS makes the sludge bulking easy, and the pythogenous sewage evidently worsen sedimentation performance of activated sludge.
