国药威奇达药业有限公司青霉素事业部污水车间恶臭气体治理及综合利用项目

大同经开区高新技术产业园

国药集团威奇达药业有限公司

山西森洱环保科技有限公司

本工程总投资万元。其中环保投资22万元。建设内容及规模：新增4座厌氧反应器及配套设施，并增加自控及水质指标监测系统，实现远程控制；新建1套处理能力为400kgH₂S/d的生物脱硫系统，配套一台10t/h沼气锅炉替代原有8t/h沼气锅炉，沼气处理量为12000m³/d。

1、大气环境污染防治措施

新建1套处理能力为400kgH₂S/d的生物脱硫系统去除厌氧工序产生的H₂S，减少污水处理车间恶臭气体排放，污水处理车间厌氧系统产生的沼气脱硫后进入沼气锅炉（拟在锅炉房新增1台10t/h的沼气锅炉替代原有8t/h沼气锅炉，）燃烧 。锅炉废气通过配套的低氮燃烧器处理后，经1根13m高的排气筒排放；污水处理站生化产生的恶臭，通过构筑物加盖、臭气收集生物除臭等方式处理， 锅炉污染物排放执行山西省地方标准《锅炉大气污染物排放标准》DB14/1929-2019中表3大气污染物排放限值；污水处理车间恶臭污染物排放执行执行《恶臭污染物排放标准》（GB14554-93）。

2、废水污染防治措施

排水主要为软化水系统排水、锅炉排水、脱硫系统排水，采取“企业自行处理+园区集中处理”的方式。企业自行处理将污水中COD浓度降至400mg/L以下后送至大同市御东污水厂集中处理。排水水质COD和氨氮排放标准执行《大同市御东污水处理有限责任公司污水处理协议》中的相关标准要求，污水其他指标执行《污水排入城镇下水道水质标准》（GB/T31962-2015）中 B 等级规定。

3、噪声污染防治措施

选用低噪声设备，生产设备全部放置于车间内，并采取基础减振措施，设置软连接，避免设备振动而引起的噪声值增加；对于风机等噪声级较大的噪声源安装在尽可能远离生活区与周围敏感点的位置，生产车间与外界增设隔墙，减少噪声对减少噪声对周围环境的影响。厂界噪声排放标准执行《工业企业厂界环境噪声排放标准》（GB12348-2008）中 2 类标准。

4、固体废物污染防治措施

固体废物主要为锅炉软水制备系统中产生的废离子交换树脂、硫膏和拆除的旧设备。废离子交换树脂可回收利用进行再生处理，拆除的旧设备不能再利用的走废旧固定资产报废处置流程，交由有资质单位处置，硫膏属于一般固废外售处理。固体废物执行《中华人民共和国固体废物污染环境防治法》和一般工业固体废物执行《一般工业固体废物贮存和填埋污染控制标准》（GB18599-2020）。
