Integrated treatment system and method for high-salt-content and high-concentration organic wastewater

Abstract

The invention discloses an integrated treatment system and method for high-salt-content and high-concentration organic wastewater. The integrated treatment system comprises a wastewater pump I, a wastewater pump II, an elution device, an evaporator, a pyrolysis carbonizer, a deslagging cooler, a combustion heat exchanger, a purifier, an induced draft fan and a chimney, according to the invention, an integrated technical scheme of first low-temperature drying and dehydration, then medium-temperature pyrolysis and carbonization, and direct recovery of waste heat of pyrolysis and carbonization products for drying and dehydration of waste water and a structural design of disturbance and dispersion of fillers in a dryer and a pyrolysis carbonizer are adopted; the problems of corrosion and blockage of drying dehydration and pyrolysis carbonization equipment and the problems of high energy consumption and high cost of the system are thoroughly solved, and finally the purpose of treating wastewater and waste salt with low energy consumption and low cost is achieved.

Description

technical field [0001] The invention relates to the technical field of industrial wastewater treatment, in particular to an integrated treatment system and method for high-salt and high-concentration organic wastewater. Background technique [0002] High-salt, high-COD industrial waste liquid, because of its high concentration of inorganic salts and a large amount of refractory organic or toxic substances, makes its harmless and resourceful treatment difficult, and has become an obstacle restricting the development of enterprises. Industrial waste liquid, which is a harmful substance, can not be disposed of in a timely and effective manner, which also poses a huge pressure on the ecological environment. Therefore, according to the characteristics of industrial waste liquid, adopt suitable and effective technology and equipment to recover the inorganic salt, realize resource utilization, and make harmless treatment, which is of great significance to the development of product...
