概述Overview图为某废水处理厂Thepictureshowsawastewatertreatmentplant收集家庭、商业建筑物和工业设施所产生的废水，并通过众多的管道，即收集系统，运输至废水处理厂。废水处理厂去除废水中的有机物、有害生物和污染物，然后排放到溪流、河流或湖泊中。Wastewaterfromhouseholds,commercialbuildingsandindustrialfacilitiesiscollectedandtransportedthroughnumerouspipes,knownascollectionsystems,toawastewatertreatmentplant.Wastewatertreatmentplantsremoveorganicmatter,harmfulorganismsandpollutantsfromthewastewaterbeforeitisdischargedintostreams,riversorlakes.图为某废水处理厂净水过程Thepictureshowsthewaterpurificationprocessatawastewatertreatmentplant

氮Nitrogen二氧化碳Carbondioxide概述Overview由于存在各种细菌和水藻等某些微生物，水体具有自我自净的能力，可将分解废水中的有机化合物，将其分解并转变成二氧化碳、氮等可吸附部分无机物的简单物质。Duetothepresenceofcertainmicro-organismssuchasvariousbacteriaandalgae,waterbodieshavetheabilitytoself-purify,breakingdownorganiccompoundsinwastewater,breakingthemdownandconvertingthemintosimplesubstancessuchascarbondioxideandnitrogenthatcanadsorbsomeinorganicsubstances.如果微生物有足够的时间来分解有机物并将其保持在一定浓度范围内，则水体的自我净化过程可代替该过程。一旦排放量和浓度上升时，就必须对其进行处理。Ifthemicro-organismshaveenoughtimetobre
