摘要
通过对尿素生产装置进行增设清污分流和环保回收槽、蒸发系统尾气洗涤水的改造、配备取样回收、造粒系统污染物的综合治理等相关改造,同时对生产操作法进行有效优化,采取无污染排塔方案,实现了"零污染,零排放"的环保管理目标,彻底解决了尿素生产过程中排放废水废气污染环境问题。
By adding a device for separating clean and contaminated flows and transforming environmental recovery tank and tail-gas scrubbing water from evaporation system and a comprehensive control of samples recovery and contaminates from granulation system as well as an effective optimization of production operation by employing a scheme of non-contaminated discharge,the aim of "zero contamination and zero discharge" is realized and thus,the environmentally-polluted problem by the discharged waste water and vented off-gases during the urea production fully solved.
