小中大一堆问题要问……
开门见山 直入主题
1.This wastewater plant discovered major concrete erosion below the settling pond aerator. The action of aerators created a vortex under the agitator causing the concrete to degrade.
我的理解是:某废水工厂发现混凝土侵蚀主要发生在沉淀池通风装置的下方。通风作用会在搅拌器下面产生涡流,导致混凝土劣化。
Q:1.1 这段话理解是否正确?erosion翻译成腐蚀还是侵蚀呢?二者还是有差别的...
1.2 第二句话该如何理解作用机理?
2.Clarifier wheel tracks are prone to deterioration caused by constant pressure of the wheel rotating over the surface.
Q:这句话如何理解?
3.Many Australian wastewater plants utilise a decant gate to manage the flow of treated water from the settling pond to lower ground ponds
Q:decant gate 是指什么?lower ground pond是指废水处理流程中的哪个池子?
4.suspended COD,dissolved COD
Q:后者我理解是溶解性COD,前者可以认为是颗粒性COD,会悬浮在废水中,需要过滤处理?
5.an energy producing STP in WA,详情见图1
Q:5.1名字解释STP和WA
5.2这个流程图有没有对应的中文解释(俺不是这个专业的...抱歉伸手)
6.Access Chambers and other concrete assets are vulnerable to chemical attack and degradation
Q:Access Chamber对应什么设备? chemical attack如何理解
7.Carbon Monoxide - 50 PPM WCA - 10 PPM
Q:WCA是什么?
