上世紀(jì)九十年代，隨著可持續(xù)發(fā)展的思想提出，不少國(guó)家也都開(kāi)始利用系統(tǒng)工程的方法。把經(jīng)濟(jì)發(fā)展與環(huán)境保護(hù)綜合考慮了起來(lái)，水處理也不單是處理已經(jīng)成形的污水，而是從源頭開(kāi)始加以控制。由于最近幾十年經(jīng)濟(jì)發(fā)展迅速，人們發(fā)現(xiàn)傳統(tǒng)給水處理工藝已經(jīng)難以滿足社會(huì)的用水需求，故而也就開(kāi)始將生物技術(shù)應(yīng)用到給水工藝當(dāng)中。不僅如此，伴隨水資源危機(jī)的產(chǎn)生，污水再利用的工藝也是成為了人們關(guān)注的一點(diǎn)。為了提高水質(zhì)，改善現(xiàn)在的環(huán)境，以生態(tài)學(xué)原理為基礎(chǔ)的土地灌溉、氧化塘等污水處理技術(shù)也是發(fā)展了起來(lái)。

  一 鋼鐵廠廢水處理工程概況

該鋼廠形成600萬(wàn)噸/年生產(chǎn)規(guī)模時(shí)，平均排水量將達(dá)到4000m3/h。廢水處理工程設(shè)計(jì)平均日處理能力9.6萬(wàn)米3，夏季最大日處理能力10.8萬(wàn)米3,其中70%作為工業(yè)補(bǔ)水回到廠區(qū)管網(wǎng)，其余達(dá)標(biāo)后排放。

  該廢水處理回用工程于2010年4月開(kāi)工建設(shè)，20012年1月主體結(jié)構(gòu)完工，2012年5月試運(yùn)行，2012年8月交付生產(chǎn)。工程占地29500㎡，新建建、構(gòu)筑物占地8041㎡，綠化覆蓋率32%，靜態(tài)投資為8643萬(wàn)元。

  廠區(qū)全部廢水經(jīng)處理后達(dá)到排放標(biāo)準(zhǔn)，其中回用水經(jīng)軟化、過(guò)濾、消毒等深度處理后，達(dá)到生產(chǎn)用水標(biāo)準(zhǔn)。

本工程進(jìn)水為典型的鋼鐵工業(yè)廢水，有機(jī)污染物含量不高，可生化性差，不適宜采用生化方法降解。本項(xiàng)目主要采用物理化學(xué)法。作為工業(yè)補(bǔ)水，在回用水深度處理中增加去除暫時(shí)硬度、總堿度軟化、過(guò)濾、消毒等工藝。

廠區(qū)排出的工業(yè)廢水用管道輸送至廢水處理廠進(jìn)水口。經(jīng)過(guò)預(yù)處理部分，用粗、細(xì)格柵將來(lái)水中較大顆粒的漂浮物去除；再由提升泵到配水構(gòu)筑物，在此投加混凝劑和石灰以及硫酸，然后將廢水分配到高密度澄清池，除去水中的懸浮物和膠體物質(zhì)，保證水的澄清度，同時(shí)外排水還有除氟工藝。總進(jìn)水的70%經(jīng)高密度澄清池處理后，再經(jīng)V形濾池過(guò)濾并投加液氯消毒后，送往廠區(qū)作為工業(yè)水的補(bǔ)充水，總進(jìn)水的30%經(jīng)高密度澄清池處理至達(dá)標(biāo)后排放。    

  濟(jì)寧天通設(shè)備有限公司是一家從事水處理設(shè)備生產(chǎn)、銷售集一體化的企業(yè)，經(jīng)過(guò)不斷的努力在國(guó)內(nèi)外獲得了供不應(yīng)求的大好市場(chǎng)，贏得了客戶的一致好評(píng)。

In the 1990s, with the idea of sustainable development, many countries began to use systems engineering methods. The combination of economic development and environmental protection has been taken into account, and water treatment has not only been to deal with the already formed sewage, but to control it from the source. Due to the rapid economic development in recent decades, it was found that the traditional water treatment process has been difficult to meet the demand of the society, they began to apply biotechnology to water supply technology. Not only that, the process of sewage reuse has also become a concern with the emergence of water crisis. In order to improve the water quality and improve the present environment, the water treatment technology, such as land irrigation and oxidation pond, which is based on the principle of ecology, has also been developed.

An overview of wastewater treatment works in a steel plant

The average displacement of the steel plant will reach 4000m to the third/h when the steel plant is produced at 6 million tons/year. The average daily processing capacity of wastewater treatment works is 96,000 m 3, and the maximum daily processing capacity of the summer is 10.8000m 3. 70% of it is returned to the factory pipe network as industrial rehydration, and the remaining discharge after reaching the standard.

The waste water treatment recycling project started construction in April 2010. The main structure was completed in January, 20012. The trial operation was conducted in May 2012 and the production was delivered in August 2012. The project covers an area of 29500 ㎡, the new building and structures which covers an area of 8041 ㎡, green coverage of 32%, the static investment is 86.43 million yuan.

All waste water in the factory will meet the emission standard after treatment, and the water will reach the standard of production water after softening, filtering and disinfecting.

This engineering water is typical of steel industry wastewater, organic pollutant content is not high, but biochemical difference is not suitable for biodegradation. This project mainly adopts physical chemistry method. As an industrial rehydration, the process of removing temporary hardness, softening of total alkalinity, filtration and disinfection is added in the treatment of water reuse.

The industrial effluent discharged from the factory is piped into the water inlet of the waste water treatment plant. After the pretreatment part, the large particles in the water will be removed by means of coarse and fine grille. By lift pump to the water distribution structures, again in the dosing coagulant and lime and sulfuric acid, and then assigned to high-density clarifier and wastewater to remove the suspended solids in the water and colloidal substances, ensure the clarity of water, drainage and fluoride in process at the same time. 70% of the total water treated with high-density clarifier, then through v-type filtration process and after adding the liquid chlorine disinfection, sent to the factory as make-up water of industrial water, 30% of the total water discharged after high-density clarifier processing to amount to mark.
