【摘要】：隨著我國社會經(jīng)濟(jì)的迅猛發(fā)展,氯堿行業(yè)之間處于明顯的激烈競爭中。由于對環(huán)�？刂屏Χ鹊募訌�(qiáng),廢水排放要求也越來越嚴(yán)格,如何將廢水進(jìn)行合理化利用是目前氯堿化工行業(yè)的一項(xiàng)艱巨任務(wù)。本論文通過翻閱大量的相關(guān)文獻(xiàn)資料,并對現(xiàn)場進(jìn)行詳細(xì)調(diào)查后,明確了電解裝置的生產(chǎn)原理和工藝過程,繪制出相應(yīng)的工藝流程簡圖,獲得裝置內(nèi)部用水和排水水量,對生產(chǎn)系統(tǒng)進(jìn)行水平衡測算；根據(jù)“清污分流、高低分用”和“循環(huán)利用、減少排放”的原則對廢水進(jìn)行階梯利用,提出一項(xiàng)經(jīng)濟(jì)有效的廢水回用方案,先針對裝置內(nèi)部的實(shí)際生產(chǎn)情況,對裝置內(nèi)部可回用廢水提出合理的工藝改造；分析氯堿廢水和PVC廢水的處理技術(shù)和中水回用技術(shù),監(jiān)測廢水水質(zhì)水量和污染物特性,廢水經(jīng)過處理后絕大部分回用于循環(huán)水補(bǔ)水,另一部分廢水進(jìn)行處理后完全符合污水排放標(biāo)準(zhǔn)(PH:6-9, SS≤70mg/L,氨氮≤15mg/L, CODcr≤100 mg/L);為加強(qiáng)裝置對廢水的回收利用,建立一項(xiàng)排污收費(fèi)及廢水綜合利用獎(jiǎng)勵(lì)制度。通過實(shí)施這項(xiàng)方案,將廢水的回收利用工作做到實(shí)處,在企業(yè)降低生產(chǎn)成本的同時(shí)實(shí)現(xiàn)經(jīng)濟(jì)效益、環(huán)保效益、國家效益的最大化,促進(jìn)企業(yè)能夠穩(wěn)定而快速的進(jìn)行可持續(xù)發(fā)展。
[Abstract]:With the rapid development of social economy in China, the chlor-alkali industry is in obvious fierce competition.Due to the strengthening of environmental protection control, wastewater discharge requirements are becoming more and more strict. How to rationalize the utilization of waste water is a difficult task in the chlor-alkali chemical industry at present.After reviewing a large number of related documents and investigating the field in detail, this paper clarifies the production principle and technological process of the electrolysis unit, draws out the corresponding process flow diagram, and obtains the internal water and drainage water of the device.To calculate the water balance of the production system, to carry on the step utilization of the wastewater according to the principles of "decontamination, high and low separation" and "recycle utilization, reduce the discharge", and to put forward an economical and effective waste water reuse scheme.In view of the actual production situation of the plant, a reasonable process reform is put forward for the reuse wastewater of the plant, and the treatment technology of chlor-alkali wastewater and PVC wastewater and the reclaimed water reuse technology are analyzed to monitor the water quality, quantity of water and pollutant characteristics of the plant.After treatment, most of the wastewater is reused for rehydration of circulating water. The other part of the wastewater is treated in full compliance with the sewage discharge standards PH6-9, SS 鈮，
