导读：5月17日的这场城镇水务发展与技术论坛，蹲点的小伙伴有没有觉得“不虚此行”呢？

　　【农机网 会展快讯】5月已经过半，但2022青岛国际水大会专家大讲堂的“接龙”之旅才正式开始！整个5月接6月，海水淡化与浓盐水综合利用专场、工业节水与污水资源化专场、城镇水务发展与技术专场、水资源可持续发展专场等8个专场陆续与您相约。
 
　　可以看到，8场连播踩准了当前水务市场备受关注的话题，如污水资源化和海水淡化两种“开源”渠道，再如水环境综合治理和水生态修复，以及与民生息息相关的净水问题，和“双碳”战略目标下必须作答的绿色、低碳、可持续“论述题”，看了才知道，是“真的香”。
 
　　同理，5月17日的这场城镇水务发展与技术论坛，蹲点的小伙伴有没有觉得“不虚此行”呢？
 
　　没有来得及看直播，虽然错过了在线互动，但是回顾也可以安排起来呀↓

 

　　演讲主题：中国合流制问题与改造
 
　　唐建国 上海市城市建设设计研究总院(集团)有限公司 总工程师
 
　　合流制、分流制是城市排水体制两种并存的形式，各有优缺，其中合流制造价低、占用道路资源和维护管理工作量相对较少，因此也是世界上较早采用的排水系统形式，并沿用至今。其缺点跟当前热点话题——雨污分流密切相关，即雨季时超过管道排水能力的会出现溢流现象。唐建国总工程师针对合流制，介绍了日本大阪、东京，德国，美国在合流制改善方面的措施和做法，包括著名的费城“绿色英亩计划”，并表示，中国“海绵城市”建设不妨吸取费城的成功经验。
 
　　同时，唐建国总工程师还指出，到底适不适合采用合流制，一看雨水标准够不够，二看截流倍数够不够，三看溢流污染大不大，我国显然这三个关键点均不能满足。“我们很多城市就埋了‘一根管’”，“一根管”可不是合流制，因此在争论合流制和分流制之前，要正确认识合流制这个概念。
 
　　那么，我国合流制到底应该怎么改呢？盲目改造不可取，快去在线论坛里找答案。

 

　　演讲主题：城镇污水处理厂深度脱氮除磷技术研究与应用
 
　　万年红 中国市政工程中南设计研究总院有限公司，副总工兼研究院院长
 
　　“我国城镇污水处理厂水污染物排放标准日益趋严，甚至趋于地表Ⅳ类标准”，在这样的背景下，北京、天津、浙江、湖南，太湖、巢湖、岷沱江等地方和流域陆续对总氮、总磷提出了高去除要求。万年红院长表示，这也对污水处理厂的深度脱氮除磷提出了比较大的需求，并就着这个问题介绍了从ENR(强化脱氮除磷)到LOT(极限脱氮除磷)的相关情况。
 
　　LOT工艺，通过强化二级处理+深度处理+超深度处理(气浮、DBAF、膜)，TN、TP可以达到准地表Ⅲ、Ⅳ类标准：TN 3-1mg/L；TP 0.1-0.05mg/L。据万年红院长介绍，目前中国市政工程中南设计研究院污水处理试验基地涵盖了从CSO-预处理、一级强化处理、二级处理、深度处理到生态处理的全过程工艺优化探索，开展的中试研究在二级生化处理、深度脱氮、高级氧化去除新污染物等方面与中国污水处理概念厂(宜兴)主流工艺路线不谋而合。
 
　　是不是越听越感兴趣了呢？再刷一遍，走起~
 


 

　　演讲主题：紫外线水处理技术研究进展与应用
 
　　贾瑞宝 山东省城市供排水水质监测中心 主任
 
　　从非强制到强制，从侧重技术要求，到增加法律效力，我国《生活饮用水卫生标准》(GB5749-2022)即将于明年4月1日正式实施。面对消毒处理要求的个中变化，紫外线消毒具有高效、广谱的特点，并且常规剂量不产生消毒副产物，对抗氯菌也有较好的灭活效果，当然对腺病毒灭活能力有限，且没有持续性消毒效果。
 
　　贾瑞宝主任分析，总的来看，我国紫外线水处理技术生产企业实力较弱，用户运维质量较差，标准体系不完善，设备整体技术水平较低。“紫外线发生器产品检测能力需要第三方认可的CMA 资质认证，促进行业技术进步和可持续健康发展”，对于行业的未来展望，贾瑞宝主任认为，国产紫外线装备+高级氧化工艺带来了可行方案。
 
　　想了解更多紫外高级氧化技术的技术和应用，当然不能错过这么精彩的分享啦~

　　演讲主题：低噪音、低振动泵技术在水务行业中的应用
 
　　吴宏飞  南方泵业股份有限公司  副总工程师
 
　　泵阀设备一直是各行各业的高能辅助，而随着近年我国对生态环境保护的重视，包括环保标准的趋严，辅助“换装”节奏也不得不跟上。南方泵业作为国内较早开始规模化生产不锈钢冲压焊接离心泵，致力于成为“绿色水动力专家”的技术型企业，早早就开始布局泵系统的节能、降碳、减排、低噪升级，为各大合作商实现自身的减污降碳目标作出了不小的贡献。
 
　　本次吴宏飞副总工程师带来的二供用泵市场背景、实现的技术以及应用案例解读，就能看出不少“含金量”。针对二供行业面临的泵类产品振动和噪音大、节能效率低、产品故障率高、老旧小区改造空间有限等等问题，南方泵业运用了什么样的低振动低噪音方案？所谓的CFD仿真分析有哪些优点？SS高效静音水务专用泵好在哪？不要犹豫，来线上论坛找答案吧。

　　喜欢本次特别策划的2022青岛国际水大会专家大讲堂的小伙伴，别忘了点赞、分享、递名片哦，继3大专场圆满落下帷幕，下次见面就是在水资源可持续发展论坛啦。
 
　　2022年5月24日，2022青岛国际水大会专家大讲堂专场四：水资源可持续发展，欢迎参与在线互动！我们，下次见！
