水处理钢铁厂废水工业废水处理设备就选济宁天通

In ancient times, humans did not have advanced water treatment techniques, and they were treated with simple grille interception and natural sedimentation in order to reduce the water spread of the disease. Then, after years of observation and summarization, they also found that the sand can be used to filter out the fine suspension, and then the coagulation pretreatment was developed. With the continuous progress of human civilization, human waste and the destruction of the environment have caused serious pollution of water resources. When all kinds of infectious diseases pass through water and cause many people to get sick or die, it is important to find out what water treatment is. It is only then that people begin to study water treatment technology.
Since the end of the 19th century, industrial technology has come a long way, and industrial sewage has been doubling every year. Moreover, the rivers and lakes of the industrial powers were severely polluted and gradually became a public nuisance. The discovery of simple chemistry, physical methods and the difficulty of dealing with them has led to new water treatment techniques. Scientists of all countries have begun to study water treatment method, is the earliest sewage aeration experiment, then the biological membrane method, then is the artificial biological treatment method, and then to now targeted ion exchange method, electrochemical processes, such as high and new technology.
Overview of wastewater treatment project in 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.
Treatment process
Wastewater design water quality
The original water of this project is a typical metallurgical industrial effluent, which is required to meet the secondary standard of local emission standard after treatment.
Treatment process
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.
The project covers an area of 29500 ㎡, north and south to decorate. The original water from the waste water is entered into the treatment plant by the west side. After treatment, the north water pump room is sent to the plant to supplement the water.
2 elevation design
The ground elevation is the relative elevation of the treatment system. The waste water is only improved by the pretreatment of the pretreatment, and then the treatment works by gravity flow.
3 construction and structure design
According to the geotechnical engineering investigation report, important structures such as high density clarifying pool, v-shaped filter and pretreatment unit fall on the pebble layer, and the foundation soil is subjected to a standard value of 400kPa. General buildings such as complex buildings are on the clay soil layer, the foundation soil bearing stress standard is 150kPa.
Adopts the public tender for the construction of the wastewater treatment projects, by our company won the bid, the main technology system of high-density clarifier, v-shaped filter, automatic dosing and the control system adopts the technology and equipment of the company. As the core unit of high-density clarifier was developed by our company a way of inclined pipe and setting and sludge circulation clarifier, treatment process covers an area of less, with high efficiency, convenient management, etc.
With advanced technology and high automation, this project has been well run since its production. The water quality is stable, the effluent suspension is less than 5mg/L, COD is less than 15mg/L, and the water content is 30%.

在古时候，当时的人类没有的水处理技术，为了降低疾病的水传播，他们便是采用简单的格栅截留和自然沉降等方法进行水处理。随后，经过多年观察和总结，他们也是发现了用砂子可以过滤掉细微悬浮物的方法，进而出现了药剂混凝预处理。随着人类文明的不断进步，人类产生的垃圾以及对环境的大肆破坏，导致了水资源受到严重污染。当各种传染病通过水传播，致使不少人染病或者死亡的时候，人们才是发现水处理是何等的重要。也正是如此，人们才逐渐开始研究水处理技术。
从十九世纪末开始，工业技术得到长足发展，工业污水也是逐年翻倍产生。而且当时的工业强国的河流、湖泊也是遭到严重污染，逐渐成为社会公害。人们发现，简单的化学、物理方法以及难以处理这些污水，研究出新型的水处理技术已经急不可耐了。各国的科学家都开始着手研究水处理方法，早是污水曝气试验，然后又是生物膜法，接着再是人工生物处理法，再到如今具有针对性的离子交换法、电化学法等高新技术。
