摘  要:
应用自行设计的臭氧深度处理装置对猪场厌氧处理废水开展曝气试验,在曝气0、10、20、40、60 min时分别取样测定各种形态磷素质量浓度。结果表明,臭氧不同曝气时间对废水体系(液体和固体)中磷素形态有显著影响。可溶性总磷、可溶性无机磷、总有机磷和颗粒态有机磷质量浓度呈下降趋势,60 min取样时分别比初始减少30.28%、41.80%、34.92%和79.53%,均达到显著性差异水平(P<0.05);可溶性有机磷、颗粒态总磷、颗粒态无机磷质量浓度呈上升趋势,60 min取样时分别比初始增加105.11%、46.74%和123.86%,均达到显著性差异水平(P<0.05)。60 min内通过磷化氢气态途径损失量极小,仅占废水体系总磷量的0.38%。废水体系中的总磷质量浓度基本保持不变。经臭氧消毒准备用于农田的猪场废水应考虑易被植物利用的速效磷的损失以及颗粒态磷素的回收。

摘  要:
As a kind of advanced oxidation technology,ozone aeration has been widely used in wastewater treatment and disinfection. Ozone aeration of piggery wastewater also significantly affects the forms of phosphorus and effectiveness,which have important effects on the utilization of pigfarm effluent regeneration in farmland. In order to study the influences of different durations of ozone aeration on the phosphorus content and form transformation in anaerobic swine wastewater,the experiment,sampling and measuring the content of phosphorus in different forms,was conducted on self-designed apparatus,with five different durations of ozone aeration,0 min,10 min,20 min,40 min,60 min,respectively. The results show that different durations of ozone aeration remarkably affect the content of phosphorus in different forms in wastewater system. Specifically,the contents of total soluble phosphorus,soluble inorganic phosphorus,total organic phosphorus and particulate organic phosphorus show decline trends with the magnitudes of 30. 28%,41. 80%,34. 92% and 79. 53% at the end of aeration lasted for 60min, respectively. By the contrary, the contents of soluble organic phosphorus, total particulate phosphorus and particulate inorganic phosphorus show upward trend,which increase by 105. 11%,46. 74% and 123. 86% at the end of 60 min( P < 0. 05),respectively. Meanwhile,the loss of gaseous phosphorus is also detected in the absorbing liquid with trace amount,which only occupying 0. 38% of the total phosphorus. The total phosphorus content in the wastewater system is basically unchanged. The loss of available phosphorus and the recovery of particulate phosphorus in the swine wastewater after ozone aeration should be taken into consideration.
