不同泥源磷源对厌氧除磷的影响

通过厌氧培养基试验,在厌氧条件下,考察始末总磷的浓度,研究了不同泥源、不同磷源、不同起始磷浓度对厌氧除磷的影响.试验研究表明在厌氧35℃避光培养条件下,以猪粪、鸡粪、具有短程同步硝化反硝化耦合除磷的污泥、SBR污泥、EGSB厌氧污泥、ASBR污泥、SBR污泥和具有同步脱氮生物化学除磷的污泥为泥源的培养基试验中,EGSB...

Effect of Diverse Mud and Phosphorus Sources on Total Phosphorus Removal Efficiencies

The paper mainly researched the effects of different mud,phosphorus and the original concentration of P on the anaerobic phosphorus removal through the anaerobic culture medium experiment,by which we compared with the original and the terminal concentrations of the total phosphorus under the anaerobic condition.The study indicated that the phosphorus removal efficiency was highest when the mud is EGSB anaerobic sludge or ASBR sludge,and it was better to remove P within the culture medium of ASBR sludge than with the EGSB sludge,compared with the shortly simultaneous nitrification and denitrification P removal sludge mixed by pig manure and fowl dung,SBR sludge and the simultaneously biochemical nitrogen and phosphorus removal sludge,if the temperature was 35 ℃ away from light.It also showed that it has the best results to remove P when using the dipotassiun hydrogen phosphate(up to 43.1 %),the monopotassiun phosphate is the second,and the sodium hexametaphosphate was the worst of the three.If using the monopotassium phosphate,as the concentration of P went up,the P removal quantity increased.However,when the total P was more than 70 mg/L,the removing P which kept 25 mg/L will not went up as the concentration increased.
