【正文】 g/L,CODcr 為 700~ 900 mg/L, PH 為 3~ 12, SS 為 300 mg/L。根據(jù)廣東省《污染物排放限值》( DB44/262020)中第二時(shí)段一級(jí)標(biāo)準(zhǔn),排放污水的水質(zhì)應(yīng)達(dá)到如下指標(biāo): Cu2+為 mg/L , Ni2+為 mg/L, CODcr 為 90 mg/L, PH 為 69, SS為 60 mg/L。線路板廢水的污泥含有銅、鎳等貴重金屬,可回收變廢為寶。s condition is Cu2+=30~50 mg/L,Ni2+=5~10 mg/L, CODcr=700~900 mg/L, PH=3~12, SS=300 mg/L. According to the province of Guangdong’s 《 pollutant exhaustion standard》 ( DB44/262020) , in which the second time a class standard limit that the exhausted waste water must reach: Cu2+= mg/L , Ni2+= mg/L, CODcr=90 mg/L, PH=6~9, SS=60 mg/L. The circuit plank manufacturing waste water, which heavy metals copper ions pollution is main,its position is plicate and its PH varies very big. Should be collected separately after pretreatment centralized. Handling plex chemical replacement, if the conditions permit, the dilution mixing method could also be used, such savings Pharmacy, reduce costs. Acidification by anic waste and in response and then regulate the inflow pool and then coagulation treatment. PCB wastewater sludge containing copper, nickel and other precious metals, recyclable waste to treasure. According to these characteristicseses of the circuit plank waste water, this design adopts the mathod that classification handles and precipitation handles for the main craft processing the circuit plank waste water. That method has the characteristics of simple craft,effective handle,simple structure,easy to operation and support and so on,which is an ideal craft to handles circuit plank waste handling the water’s various index signs that all attain the 《 exhaustion standard in dirty water 》 in Guangdong province Key words: circuit plank waste water , heavy metal , the classification handles, physics and chemistry precipitation 目 錄 1 前言 ........................................................................................................................................ 1 處理廢水類(lèi)型及流量 ...................................................................................................... 1 設(shè)計(jì)進(jìn)水水質(zhì) .................................................................................................................. 1 設(shè)計(jì)出水水質(zhì) .................................................................................................................. 1 設(shè)計(jì)依據(jù) .......................................................................................................................... 1 設(shè)計(jì)范疇 .......................................................................................................................... 2 設(shè)計(jì)原則 .......................................................................................................................... 2 2 線路板廢水的處理工藝比較 ................................................................................................ 3 線路板廢水的水質(zhì)特性 .................................................................................................. 3 線路板廢水處理方案比較 .............................................................................................. 4 離子交換法處 理線路板廢水 ................................................................................ 4 氣浮法處理線路板廢水 ........................................................................................ 5 分類(lèi)處理的物化沉淀法處理線路板廢水 ............................................................ 6 線路板廢水處理工藝方案選擇 ...................................................................................... 7 3 工程設(shè)計(jì) ................................................................................................................................ 9 設(shè)計(jì)計(jì)算部分 .................................................................................................................. 9 各構(gòu)筑物、設(shè)備單元設(shè)計(jì) .............................................................................................. 9 含鎳重金屬?gòu)U水預(yù)處理部分設(shè)計(jì)計(jì)算 ................................................................ 9 含絡(luò)合物的廢水預(yù)處理部分設(shè)計(jì)計(jì)算 .............................................................. 10 有機(jī)廢水預(yù)處理部分的設(shè)計(jì)計(jì)算 ...................................................................... 14 綜合廢水處理設(shè)計(jì)計(jì)算 ...................................................................................... 20 污泥處理系統(tǒng)的設(shè)計(jì)計(jì)算 .................................................................................. 28 線路板廢水處理工程設(shè)備的選型 ................................................................................ 31 含絡(luò)合物的廢水預(yù)處理部分的設(shè)備選型 .......................................................... 31 有機(jī)廢水預(yù)處理 部分的設(shè)備選型 ...................................................................... 32 綜合調(diào)節(jié)池到中和絮凝池的設(shè)備選型 .............................................................. 32 斜管沉淀池的污泥泵選型 .................................................................................. 33 活性炭吸附池到清水池的泵選型 ...................................................................... 33 線路板廢水處理工程的總體布置 ................................................................................ 33 平面布置 .............................................................................................................. 33 高程布置 .............................................................................................................. 34 4 工程投資概算及效益分析 .................................................................................................. 35 主要構(gòu)筑物、建筑物及投資概算一覽表 .................................................................... 35 各類(lèi)設(shè)備投資概算一覽表 ............................................................................................ 36 總投資概算 .................................................................................................................... 37 效益分析 ........................................................................................................................ 37 結(jié)語(yǔ) .......................................................................................................................................... 39
