style="text-indent:25px">酸堿廢水：高濃度含酸含堿廢水來源比較廣，化工、化纖、制酸、電鍍、煉油以及金屬加工廠、酸洗車間等都會排出酸性廢水。有的廢水含有無機酸如硫酸、鹽酸等，有的則含有蟻酸、醋酸等有機酸，有的則兼而有之。廢水含酸濃度差別比較大，從小于1%到10%以上都有。造紙、印染、制革、金屬加工等生產(chǎn)過程會排出堿性廢水，大多數(shù)情況下含有無機堿，也有含有機堿。某些廢水的含堿濃度較高可達百分之幾。廢水中除含有酸、堿外，還可能含有酸式鹽和堿式鹽，以及其他酸性或堿性的無機物和有機物等物質(zhì)。將含有酸堿的廢水隨意排放不*會對環(huán)境造成污染和破壞而且也是一種資源的浪費。因此對酸、堿廢水首先考慮回收和綜合利用。當酸、堿廢水濃度較高時，例如含酸廢水含酸量達到4%以上、含堿廢水含堿量達到2%以上時，寧波高濃度工業(yè)廢水處理系統(tǒng)，就存在回收和綜合利用的可能性，可用來制造硫酸亞鐵、石膏、化肥，也可以回用或供其他工廠使用，寧波高濃度工業(yè)廢水處理系統(tǒng)。濃度低于4%的酸性廢水和濃度低于2%的堿性廢水由于回收利用意義不大，寧波高濃度工業(yè)廢水處理系統(tǒng)，會進行中和處理。過去幾年，廢水處理行業(yè)的產(chǎn)業(yè)能力發(fā)生了質(zhì)的變化。寧波高濃度工業(yè)廢水處理系統(tǒng)</p><div

style="text-indent:25px">化學還原法是利用硫酸亞鐵、亞硫酸鹽、二氧化硫等還原劑將廢水中六價鉻還原成三價鉻離子，加堿調(diào)整pH值，使三價鉻形成氫氧化鉻沉淀除去。這種方法設(shè)備投資和運行費用低，主要用于間歇處理。常用處理工藝為在第1反應(yīng)池中先將廢水用硫酸調(diào)pH值至2～3，再加入還原劑，在下一個反應(yīng)池中用NaOH或Ca(OH)2調(diào)pH值至7～8，生成Cr(OH)3沉淀，再加混凝劑,使Cr(OH)3沉淀除去。改良的工藝為在第1反應(yīng)池中直接投加硫酸亞鐵，用NaOH或Ca(OH)2調(diào)pH值至7～8，生成Cr(OH)3沉淀，再加混凝劑，使Cr(OH)3沉淀除去。使用該技術(shù)后，含鉻廢水日處理量為1000M3,廢水中鉻含量為10mg/l。該技術(shù)適用于含鉻工業(yè)廢水處理。在一些報道中也有提到利用聚合氯化鋁鐵處理電鍍含鉻廢水。聚合氯化鋁鐵兼有傳統(tǒng)絮凝劑PAC,PFC的優(yōu)點,形成的絮凝體大而重,沉降速度快。其出水色度比聚合氯化鐵好,除濁效果和絮凝體沉降性能又優(yōu)于聚合氯化鋁。具體報道內(nèi)容附于文后。鄞州區(qū)洗砂廢水處理方法有哪些從對水體的污染來說，主要是石油和焦油。</p><div

style="text-indent:25px">苯甲醛是一種重要的精細化學品，每年市場需求量5～8萬t。其生產(chǎn)方法主要有兩種，一種是甲苯氧化法，另一種是氯化水解法。氯化水解法工藝中副產(chǎn)品苯甲酸通常以苯甲酸鈉形式和少量苯甲醛混雜在含高濃度氯化鈉的污水中。可以通過調(diào)節(jié)pH，將苯甲酸鈉轉(zhuǎn)化為苯甲酸，從而分離出大部分苯甲酸鈉。但是苯甲酸和苯甲醛在污水中總殘留仍然高達2%～4%。通過鼓氣氧化，水中的苯甲醛可以轉(zhuǎn)化為苯甲酸，二次分離出苯甲酸，污水中結(jié)尾剩余苯甲酸濃度低于1%。通過多效蒸發(fā)或MVR蒸發(fā)，可以濃縮出混有苯甲酸的氯化鈉。一方面，蒸發(fā)過程中苯甲酸不斷在蒸發(fā)設(shè)備的換熱器部件上積累，導致?lián)Q熱效率越來越差，系統(tǒng)運行一段時間，就會被迫停車清洗；另一方面濃縮出的鹽含有苯甲酸屬于危廢。為了延長蒸發(fā)設(shè)備運行周期；將危廢變成有用的工業(yè)鹽；開發(fā)出預處理工藝，提前分離出污水中苯甲酸。對于苯甲酸降解處理目前主要有生物法和化學法。但是苯甲酸本身也是一種資源，因此首先應(yīng)該考慮經(jīng)濟的回收利用。水相中的低濃度苯甲酸分離、回收主要方法是萃取和吸附。無論用到何種溶劑萃取，都會帶來新的VOCs排放和溶劑在水中的殘留，因此，采用吸附法分離苯甲酸。</p><p style="text-indent:25px">電鍍生產(chǎn)使用的原輔料較多，除使用鍍種對應(yīng)的金屬鹽外，還使用了大量無機和有機材料，其中包括無機配位劑與有機配位劑，常見的無機配位劑有氰根、焦磷酸根、多磷酸根、氨等，有機配位劑主要包括有機酸、有機膦和胺三類，這些配位劑會與金屬離子形成溶解態(tài)的配合物。含溶解態(tài)配合物的電鍍廢水*用普通化學沉淀法處理的效果有限，需先采用氧化、酸化水解等方法去除配位劑，使得金屬離子游離在溶液中后，再添加化學沉淀劑進行沉淀。有的電鍍企業(yè)或園區(qū)目前仍采用單一的化學沉淀法來處理電鍍廢水，無去除配位劑的破絡(luò)環(huán)節(jié)，或是有破絡(luò)環(huán)節(jié)但破絡(luò)不徹底，這些因素均會造成鎳、銅、鋅等金屬離子存在于溶解態(tài)的配合物中，難以通過化學法沉淀去除，從而導致出水超標。另外，氫氧化鋅、氫氧化鉻(III)等屬于兩性氫氧化物，若pH調(diào)節(jié)不當(過高或過低)，均會造成沉淀不完全，影響去除效果。微生物的代謝，使廢水中呈溶液、膠體以及微細懸浮狀態(tài)的有機污染物，轉(zhuǎn)化為穩(wěn)定、無害的物質(zhì)的廢水處理法。</p><div
