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)過預(yù)處理部分，用粗、細(xì)格柵將來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)過不斷的努力在國內(nèi)外獲得了供不應(yīng)求的大好市場，贏得了客戶的一致好評。

多年的發(fā)展歷程，公司始終堅(jiān)持創(chuàng)新、品質(zhì)、服務(wù)、敬業(yè)、感恩的理念。采納新創(chuàng)意，嚴(yán)格質(zhì)量，全方位的服務(wù)跟蹤，堅(jiān)持做出高品質(zhì)產(chǎn)品。

Basic requirements of industrial sewage treatment process

Industrial sewage treatment is an important part of industrial development in China, and industrial sewage treatment is related to industrial development of China, economic and livelihood of the economy, industrial sewage treatment

1 mature industrial wastewater treatment technology, economic and reasonable principle for overall design, makes every effort to saving energy and reducing consumption, lower engineering investment, low running cost, convenient operation and management, advanced and mature technology of wastewater treatment process.

2. The process can be stable, efficient, resilient to impact load, flexible in operation and reasonable structure of equipment layout;

3. Selection of industrial sewage treatment equipment, proper matching, stable and reliable operation, high cost performance, simple maintenance and long service life;

General situation of wastewater treatment project in steel mill

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.

Jining day general equipment co., LTD. Is a company engaged in water treatment equipment production, sales integration enterprise, after continuous efforts won the demand of the market both at home and abroad, won the customer consistent high praise.
