Description
Technical Field
The invention relates to a weak electric pulse activation-quenching agglomeration desalting reactor for treating industrial wastewater, belonging to the field of wastewater treatment in environmental protection.
Background
Under the background of global climate change and energy shortage, a low-carbon economic development mode based on low energy consumption, low pollution and low emission is valued, and the steel industry as the industry with high energy consumption and multiple emissions bears important responsibility in the work of energy conservation and emission reduction advocated by global low-carbon economy.
The steel industry has become an important force for leading the world steel industry as a basic industry for industrial development in China, and the scale and development momentum of the Chinese steel industry draw attention to the world. However, the steel industry is not only a water-consuming consumer but also a pollution-discharging consumer, and with the rapid development of the modern industry, the problems of the water consumption sharply increased, the water resource shortage, the serious water pollution and the like become the bottleneck of the development of the steel industry in China. To solve the problem, the most direct, economic and effective way is to research and develop a set of advanced steel industry wastewater purification treatment technology.
The research work of the steel industry wastewater purification treatment technology and equipment is work with great social benefit and economic benefit, but in the wastewater treatment process of steel enterprises, if a desalination treatment process is not arranged, the salt content of the treated wastewater is very high, and after the wastewater is used as circulating water and is concentrated by high times, the concentration of various ions in the wastewater is increased, a series of physical and chemical changes can be generated, so that the corrosion and scaling of a pipeline system are caused, the normal operation of the equipment is seriously influenced, and the service life of the equipment is shortened.
At present, the desalination technology of the wastewater of the steel industry in China mainly comprises three types, namely an ion exchange method, a double-membrane desalination method and an electro-adsorption desalination method.
(1) Ion exchange method:
the ion exchange method is a mature and effective water treatment process, and the desalting effect is good. However, the method has the defects of large occupied area of equipment, frequent and complex system operation and maintenance and periodic fluctuation of effluent quality, and is easy to generate secondary pollution and not beneficial to the protection of ecological environment because a flocculating agent needs to be added and a large amount of acid and alkali is consumed.
(2) Double-membrane desalination method:
the double-membrane desalination method mainly refers to a treatment process of ultrafiltration and reverse osmosis, and the process mainly adopts a membrane separation technology to prepare desalted water.
The ultrafiltration principle is a principle of a membrane separation process, and utilizes an organic or inorganic ultrafiltration membrane to intercept colloids, particles and high molecular weight substances in water under the action of external pressure, while water molecules and small solute particles can permeate the ultrafiltration membrane. After the water passes through the ultrafiltration membrane, most of the colloidal silica contained in the water can be removed, and a large amount of organic matters and the like can be removed. Reverse osmosis is a process in which the solvent in solution is separated by a reverse osmosis membrane with sufficient pressure to reverse the direction of natural osmosis, and is therefore referred to as reverse osmosis.
The double-membrane desalination method has the advantages of high water production quality, high automatic control degree, easy operation and control and the like. However, the method also has the defects of high requirement on the quality of inlet water, small impact resistance, difficult repair of membrane damage and the like, and meanwhile, a large amount of chemical agents such as scale inhibitors and the like are required to be used in the process of using membrane outlet water.
(3) Electro-adsorption desalination method:
the electro-adsorption desalination technology is a new water purification technology, and the basic principle is that salt-containing water flows between a positive electrode and a negative electrode, ions in water respectively migrate to the electrodes with opposite charges when the water is electrified, and the ions are adsorbed on the surfaces of the electrodes by the electrodes to form an electric double layer. Along with the enrichment and concentration of ions/charged particles on the surface of the electrode, the concentration of dissolved salts, colloidal particles and other charged substances in water is greatly reduced, thereby realizing the desalting, hardness removal and purification of water. During regeneration, only the electrode needs to be short-circuited, and adsorbed ions are released from the surface of the electrode so that the electrode is regenerated.
The electro-adsorption desalination method is of interest because of its high practicability, wide application range and low treatment cost. The electro-adsorption technology has wide application prospect in the fields of iron and steel industry circulating water desalination treatment and wastewater recycling. However, the electro-adsorption desalination technology has disadvantages, such as that the desalination efficiency needs to be further improved, the self-regeneration time of the electrode is longer, and generally accounts for one third of the whole period, and the water yield is influenced.
At present, the existing method for treating inorganic salts in the wastewater in the iron and steel industry has the problems of large occupied area of equipment, frequent and complex system operation and maintenance, small impact resistance, easy damage of equipment, low desalting efficiency, secondary pollution and the like. Therefore, there is a need to get rid of the existing treatment technical idea, develop a new way for treating the salt-containing wastewater in the steel industry, and further develop a new form of treatment technology for inorganic salts in the wastewater in the steel industry.
