微纳米臭氧曝气协同好氧菌治理地表水试验研究
Experimental Study on Surface Water Treatment by Micro-Nano Ozone Aeration Combined with Aerobic Bacteria
摘要
Abstract
A certain oilfield has a rich number of ponds and marshes,which are distributed in various regions of the oilfield,with great differences in water quality and quantity.Due to poor connectivity and limited water source replenishment,the self-purification capacity of the ponds and marshes are weak,which easily causes frequent fluctuations in water quality.Orthogonal experiments were conducted by micro-nano bubble combined with aerobic bacteria technology to study the effects of different water volumes,air volumes,and aeration durations on water pH,dissolved oxygen(DO),chemical oxygen demand(COD),total nitrogen(TN),and total phosphorus(TP).Under the optimal condition of micro-nano aeration combined with aerobic bacteria technology:aeration duration of 3 h,air volume of 5 L/h,aeration water volume of 3 L,aerobic bacteria dosage of 0.1 g,and settling time of 48 hours,the removal rate of COD,NH3-N,TN,and TP were 20.73%,33.38%,30.22%,and 36.36%,respectively.Range analysis method was used to analyze the impact of variables on the experimental results.The results showed that the aerobic bacteria dosage exerted the greater influence than settling time and aeration duration.After ozone aeration for 30 minutes,the DO content increased by 47.11%,while COD and TN decreased by 14.46%and 22.44%,respectively,demonstrating rapid water quality improvement capabilities of the technology.The mechanism analysis of nitrogen removalvia micro-nano aeration combined with aerobic bacteria revealed that the reduction of TN was mainly attributed to the decreased in organic nitrogen and NH3-N.关键词
