【摘要】：油田处理三元污水初期主要采用“连续流曝气沉降+两级过滤”工艺,为进一步提高沉降效果,改为采用“连续流气浮、序批曝气沉降+两级过滤”工艺,配套气水联合反冲洗、提温反冲工艺。同时开展了微生物处理三元污水的研究,确定处理效果。本文分析和研究了三元污水站连续流气浮沉降的运行工艺进行优化,对比不同见剂阶段不同运行参数时的沉降效果,优化了气浮工艺回流比、溶气量等参数,确定最佳的运行参数,提高三元污水处理效果,优化了序批沉降工艺运行液位并与连续流气浮沉降工艺进行了效果对比。同时对过滤段气水联合反冲洗工艺、提温反冲洗工艺进行参数优化,提高了滤料再生效果。研究了微生物处理三元污水的可行性及处理效果,并对处理工艺提出了建议。
[Abstract]:In the initial stage of oilfield treatment of ternary sewage, the process of "continuous flow aeration settlement two-stage filtration" is mainly adopted. In order to further improve the settlement effect, the process of "continuous flow air flotation, sequential batch aeration settlement two-stage filtration" is adopted. Matching gas and water combined backwashing, temperature-raising backwash process. At the same time, the microbial treatment of ternary wastewater was studied to determine the treatment effect. This paper analyzes and studies the operation technology of continuous flow air floatation in the three Yuan sewage station, compares the settling effect with different operating parameters in different agent stage, optimizes the reflux ratio and dissolved air volume of air floatation process, and so on. The optimal operation parameters were determined, the effect of ternary sewage treatment was improved, the liquid level of sequential batch settling process was optimized and the effect was compared with that of continuous flow air floatation process. At the same time, the parameters of air and water combined backwashing process and temperature-raising backwashing process were optimized to improve the regeneration effect of filter media. The feasibility and effect of microbial treatment of ternary wastewater were studied, and some suggestions were put forward.
