海上平台FM200管道设计及喷头布置

为使灭火系统管线设计更合理、规范、科学，本论文结合工程实例，通过对选用七氟丙烷（FM200）气体灭火系统的系统管网布置、喷头布置方式的论述，依据国家和行业现行的有关标准规定，分析了进行工程设计时应考虑的条件、要求以及在设计过程中对不同问题的解决处理方法。

Design of FM200 Pipelines and Layout of Spray Nozzles on Offshore Platform

Based on the theory of industrial ecology, the self-made expanded bed with waste material A and sand as electrocatalytic electrode was used to treat coking wastewater from a coking plant. The results show that the expanded bed with particle group electrode can effectively treat coking wastewater; under the conditions of pH=9.0, aeration rate 80 L/min, retention time 3.0 h, working voltage 9.0 V, COD can be reduced from 1 062 mg/L to 497 mg/L, especially refractory heterocyclic compounds containing N can be degraded.
