Description
技术领域
本发明涉及一种污水二级生化处理装置产生废气的处理方法，属于废气处理技术领域。
背景技术
污水二级生化装置在运行过程中产生的废气主要成分有硫化氢、氨、甲烷、甲硫醇、甲硫醚、苯、甲苯、二甲苯等。一般情况其非甲烷总烃浓度<300mg/m3，硫化氢<30mg/m3，氨<8mg/m3，苯系物<30mg/m3，臭气浓度<10000mg/m3，其中比较难处理的是苯系物。
常用的污水二级生化处理装置废气处理技术有：化学氧化法、吸附、吸收法、生物滴滤过滤法等。
燃烧法利用燃烧将废气污染物成分进行氧化，但存在氮氧化物超标问题，投资和运行成本也高。化学氧化法和冷凝法和吸附法存在选择性，不能做到全面达标，同时运行成本也高，生物滴滤过滤法利用附着生长在填料上的微生物代谢降解废气，对苯系物等难降解物质的处理效果有限，不能做到直接达标排放。
发明内容
为了克服现有技术的不足，本发明提供了一种污水二级生化处理装置产生废气的处理方法，先采用碱洗法，通过循环碱液喷淋和废气对流接触进行化学中和及吸附废气中的酸性成分；再通过生物滤池利用生物法去除容易降解的有机物成分；经过除湿预处理设施后，再利用臭氧的强氧化性氧化、净化污染物；最后利用活性炭吸附对残余的有机物进行彻底吸附去除。
以下是本发明解决上述问题的技术方案。
一种污水二级生化处理装置产生废气的处理方法，其特点在于，具体步骤如下：
1)对各污水池进行加盖，通过废气管道收集废气；
2)步骤1)得到的废气依次进行碱洗、生物滤池、臭氧氧化和除湿处理；
3)步骤2)得到的废气进入臭氧反应器，利用臭氧的强氧化性在催化剂的作用下对废气中的污染物进行氧化去除；
4)步骤3)得到的废气再进入活性炭吸附装置对残余的有机物成分进一步吸附，最后通过排放筒排放。
步骤1)中，利用后置引风机抽废气，保障整个系统处于微负压，避免废气外泄。
步骤2)中，碱洗塔中投加30％氢氧化钠溶液，控制pH 9-12。
步骤2)中，除湿处理中控制废气湿度<72.5％，温度<45℃。
步骤2)中，臭氧反应器中利用臭氧的强氧化性分解去除污染物。
步骤2)中，系统阻力<2000pa。
与现有技术相比，本发明的有益效果在于：
1)通过几个工艺的组合互补短处，相互配合，实现废气污染物成分的全面去除和达标。
2)利用臭氧发生器产生的臭氧，对有污染物进行氧化去除。
3)运行操作简单，维护方便，投资和运行成本低，无安全风险。
具体实施方式
下面将通过具体的实施方案对本发明作进一步的描述
实施例【1～5】、比较例【1～2】中废气为石油化工企业的PTA污水处理场产生的废气，进气成分为：
废气量60000m3/h
温度40～60℃
湿度>95％
非甲烷总烃～300mg/m3
硫化氢～30mg/m3
氨～15mg/m3
苯～30mg/m3
臭气浓度3000～10000
实施例【1～5】
PTA污水场产生的废气通过废气收集管道，在后置引风机的抽吸下进入碱洗塔，利用循环喷淋泵进行喷淋碱洗，碱洗塔集水池中投加30％液碱，然后废气进入生物滤池，与填料上的微生物接触进行代谢降解。然后废气经过除湿机进行除湿后，进入臭氧反应器，利用臭氧的强氧化性在催化剂的作用下对废气中的污染物进行氧化去除，再进入活性炭吸附装置对残余的有机物成分进一步吸附，最后通过30米高排放筒排放。
比较例【1-2】
污水二级生化处理装置产生的废气通过废气收集管道，在后置引风机的抽吸下进入生物滴滤池，利用循环喷淋泵进行喷淋水洗，再进入生物过滤池，与填料上的微生物接触进行代谢降解，通过30米高排放筒排放。
