深市消费行业龙头企业加大股东回报力度中国石化获专利，废纺污水处理串联合成氧化与吸附工序
11月6日，中国石化（600028）的发明专利《一种废纺污水中1,4-二噁烷的处理装置以及方法》获授权，申请号为CN202311533887.6。
这项技术把纺织废水中难处理的1,4-二噁烷列为目标污染物。污水从进水罐先进入兼有厌氧和好氧阶段的反应器，再经光芬顿反应处理，之后才进入装有改性活性炭和改性沸石的吸附池。处理后的水进入末端水池。设计将生物处理、氧化和材料吸附接在同一流程内，吸附材料的搭配是其中单独规定的一个环节。
截至此次授权消息披露时，中国石化今年获得的各类专利授权共5047项，比上年同期增加30.89%。在2026年上半年，公司研发投入为77.85亿元，同比增长25.85%。企业知识产权记录中，中国石油化工股份有限公司名下可查到95016条专利信息和1687条著作权信息。
