Gongye shui chuli, 2019 米桑油田开发产生大量的高温采出水，为满足油田生产和环保要求，需配套建设采出水处理系统，处理规模为2万m3/d。原油脱水系统来水含油量≤ 1 000 mg/L、悬浮物≤ 500 mg/L、硫化氢≤ 200 mg/L。针对采出水物性，工艺采用"调储缓冲+聚结除油+混凝沉降+气提脱硫+两级过滤"压力式流程对采出水进行处理，全流程密闭隔氧，处理后净化水达标用于油田注水。项目投产运行两年多，装置运行效果稳定，具有很好的工程借鉴意义。

Behavioral interventions to reduce demand for threatened freshwater turtles as pets
Conservation Biology, Volume 40, Issue 5, October 2026.Abstract Growing demand for freshwater turtles as pets has fueled illegal trade and accelerated wild population declines, underscoring the need for theory‐based demand‐reduction interventions. We conducted a three‐part randomized controlled trial with active turtle keepers (n = 1800) in China to test conservation‐ and legality‐framed messages by ...

Gongye shui chuli, 2021 采用电絮凝技术去除超稠油高温采出水中的有机物和悬浮物，研究极板面积、电流强度和电压、进水pH、水温对处理效果的影响。结果表明，去除有机物尤其是石油类时，应增大极板面积，提高反应电流，保持反应温度，并在pH中性条件下运行。去除悬浮物，应后置固液分离单元强化絮体去除。电絮凝法能有效去除超稠油高温采出水中的有机物，且不需额外加入药剂，不会恶化循环利用采出水的水质。

Rare Metals, Volume 45, Issue 9, September 2026.ABSTRACT Ti‐15Mo‐2.5Ag alloy exhibited a low modulus and strong antibacterial ability but poor bioactivity. To resolve this problem, sandblasting and anodization were used to create a hydrophilic and nano‐Ag2O‐containing TiO2 coating. Subsequently, the microstructure and physicochemical properties were investigated by scanning electron microscopy, X ...
