1、,拯救我們的家園環(huán)境工程,環(huán)境工程,水體污染控制,水體污染的控制措施,除加強(qiáng)污染源的管理,以降低廢水量和污染量外,政府應(yīng)制定和頒布法規(guī)以控制廢水的排放,如中國(guó)政府制定和頒布了中華人民共和國(guó)水污染防治法、工業(yè)“三廢”排放試行標(biāo)準(zhǔn)等法規(guī)。城鎮(zhèn)應(yīng)建設(shè)完善的排水管系和廢水處理廠,并制定和實(shí)施管理制度。工業(yè)布局和工藝要考慮環(huán)境要求。生產(chǎn)廢水必須處理后出廠(見工業(yè)廢水治理),廢水再用,特別是建立廢水灌溉系統(tǒng),是防止廢水污染水體的有效途徑。,水體污染控制,水體污染物主要有:病原體,如病菌、病毒和寄生蟲卵等;來源于動(dòng)植物的有機(jī)物,如動(dòng)植物排泄物、動(dòng)植物殘?bào)w、機(jī)體的組分等,它們?cè)谒w中的細(xì)菌作用下消耗溶解氧;植
2、物養(yǎng)料,主要有氮、磷化合物,將使潺湲的水體出現(xiàn)富營(yíng)養(yǎng)化;有毒有害的化學(xué)品,如含氯農(nóng)藥(DDT、六六六等)、表面活性劑、重金屬鹽類、放射性物質(zhì)等;其他,如油脂、酸、堿、溫水,懸浮物等(見廢水水質(zhì))。,固體廢物處置,固體廢物的處置方法,掩埋,焚化,加工利用,掩埋,焚化,加工利用,固體廢物處置,噪聲污染控制,干擾人們休息、學(xué)習(xí)、生活和工作,甚至影響健康的聲音,統(tǒng)稱為噪聲。噪聲由許多純音組成。純音(單頻率的聲音)的聲壓(p)可用與基準(zhǔn)聲壓(p0接近一般人的聽閾,通常采用p0210-5帕)相比的聲壓級(jí)(Lp)表示,單位為分貝(dB),它的數(shù)學(xué)表達(dá)式為L(zhǎng)p201g(p/p0)。噪聲強(qiáng)弱的測(cè)定較復(fù)雜,不但要
3、結(jié)合各純音的頻率,還要結(jié)合人的主觀感受。有多種方法量度,一般采用聲級(jí),單位也用分貝。聲級(jí)可用聲級(jí)計(jì)直接測(cè)得。聲級(jí)增加40分貝,聲壓約增百倍,干擾大大增加。一般認(rèn)為低于85分貝時(shí)不致影響聽力。噴氣飛機(jī)起飛時(shí)的噪聲達(dá)150分貝,使耳鼓發(fā)痛。160分貝的噪聲使人致聾。噪聲還影響人的中樞神經(jīng)系統(tǒng)和心血管系統(tǒng),會(huì)導(dǎo)致神經(jīng)衰弱和心血管病。噪聲還影響講話和電話的使用??墒谷酥旅@的噪聲還影響某些儀表的使用。,噪聲污染控制,噪聲主要來自機(jī)器(工業(yè)噪聲)和交通工具(交通運(yùn)輸噪聲)??刂圃肼暿紫仁遣挥眯鷩痰脑O(shè)備:或則改革工藝,如改鉚接為焊接;或則改換機(jī)械,如用壓樁機(jī)替代打樁機(jī)。其次是革新機(jī)械的構(gòu)造和材料,如提高部件
4、精度減少碰撞,用非金屬材料替代金屬材料,傳動(dòng)部件用彈性構(gòu)件,整機(jī)采用隔振機(jī)座或隔聲罩,排氣口設(shè)消聲器,交通工具外形采用流線型等。再次是正確操作,如正確使用潤(rùn)滑劑,正確使用喇叭等音響設(shè)備。建立隔聲屏障(如墻、土丘)或建筑表面多用吸聲、隔聲材料,以及城市合理規(guī)劃等等,也是有效的措施(見飛機(jī)場(chǎng)環(huán)境保護(hù))。,還行,空氣質(zhì)量,大氣污染控制,一般,空質(zhì)量,重組上市,2003,2004,2010,近年空氣質(zhì)量,Click to edit title style,Description of the contents,Text in here,ThemeGallery is a Design Digital
