环保局实习报告

环保局实习报告 关于在梧州市环境监测站的暑假实习报告 在这个告别大三的暑假中，我在梧州市环境保护监测站度过了一段有意义的时光。我利用暑假中四个星期的时间，在监测站的分析科进行了实习。实习内容主要是在实验室中独立或辅助完成环境监测样本的分析实验。在这次实习中，我收获了很多，包括动手能力、执行能力的提高，工作经验的积累，课本知识的巩固，人际交往技巧的提升等等。现将此次实习的有关情况报告如下: 分析科一天的工作需要等采样科的同事到实地采样后才开展。所以，几乎每天上午的工作是为下午的分析实验做好准备工作。比如，检验水体悬浮物含量的实验要事先干燥并称量滤纸供实验使用;细菌检测的实验所用的试管要在上午做好高压蒸汽灭菌处理。我在协助同事们做好这些工作的同时还阅读了监测站样本分析的指导书本《空气和废气监测分析》、《水和废水监测分析方法》，了解分析实验原理、步骤及注意事项。 经过一个上午的准备，下午的各项分析工作就可以有条不紊地展开。开始的几天，我在实验室观察前辈做实验，帮忙打打下手，听前辈讲解操作原理和注意事项并认真做好笔记，下班后对照笔记再重新阅读专业书本，以便自己能吃透实验，保证操作时少出错。 经过几天的观摩，我终于能在前辈的指导下进行实验操作了。在实验中，前辈指出了我很多操作不规范的地方，例如分光光度仪的比色皿每次放置都应顺着统一方向以保持光路的方向性，减小误差。他们还帮助我纠正了滴定时的错误手势等。前辈们不仅指导具体工作，还无私地介绍自己的工作与社会经验，使我受益匪浅。真的很感谢他们。因为前辈们的信任，我得到了一些独立操作实验分析项目的机会。在实习期间，我独立进行了测定水体pH值、电导率、CODposition, ensure party always in thought, and political Shang, and action Shang with Central keep height consistent, makes we party always became has ideal, and has faith of Marx doctrine party.
