废水中硫化氢快速检测及加药控制装置
本技术属于石油天然气开采
,更为具体地,涉及一种废水中硫化氢快速检测及加药控制装置。
技术介绍
随着我国天然气的迅猛发展,在勘探开发过程中,从地下采出天然气的同时往往也会采出气田水,气田水作为气田开发的伴生产物,通常含有对人体和环境有较大伤害的物质,如某些高含硫气田水含有相当的硫化氢。如果大量硫化氢进入到空气中,会对生态环境造成了巨大的威胁,不符合我国的可持续发展重要战略;同时,当硫化氢在空气中含量为0.05m/L时,人就会中毒,而当大于1mg/L时,将导致人死亡,污水中的硫化氢易挥发,会严重危害周围居民健康;并且污水中的硫化氢会加剧钢的渗氢作用,导致氢脆,加速金属材料的腐蚀,显著降低设备的使用寿命。近年来,随着国家对环保要求的进一步加强,对石油天然气开发工业废水排放提出了更高的要求,在满足国家要求的同时保证整个水处理工艺、设备长期稳定、可靠运行,所以采取合适的方法对废水中的硫化物进行有效处理显得尤为迫切。目前处理含硫污水的方法有如下几种:1、物理分离法,包括:蒸汽气提法、真空抽提法和吸附法,缺点是设备庞大。2、氧化法,包 ...
