Problems solved by technology

However, during the operation of the conventional advanced treatment process, the problems of organic pollution and inorganic salt scaling of the membrane system are easy to occur, making it difficult for the process to operate stably for a long time
In addition, the recovery rate of conventional advanced treatment process wastewater is low and the output of concentrated water is large. If a large amount of pollutants are concentrated in concentrated water and discharged directly, it will cause serious environmental pollution.

Abstract

Provided is a resource recycling and treatment technology of high-concentration degradation-resistant salt-containing organic waste water.The technology comprises the following steps of the pretreatment process, the biochemical treatment process, the advanced pretreatment process, the advanced treatment process and the concentrated water treatment process.According to the technology, multiple process combinations are optimized, degradation-resistant organic matter and inorganic salts in the waste water can be removed step by step, and resource recycling of the high-concentration degradation-resistant salt-containing organic waste water is achieved on the basis of nearly zero emission; the recycling rate of produced water produced after the treatment process can reach 95% or above, and the produced water can be used as water for a production technology and replenishing water for circulating cooling water.According to the resource recycling and treatment technology of the high-concentration degradation-resistant salt-containing organic waste water, the water quality requirement of biochemical reaction inlet water is guaranteed; due to the fact that fluorine ions are removed through a fluorine removing reactor, and calcium and magnesium ions are removed through a resin softening device, the risk of inorganic salt scaling of a subsequent desalination system is greatly reduced; the risk of organic matter contamination of the subsequent desalination system is effectively reduced by means of biochemical treatment and an advanced oxidation reaction.

Description

technical field [0001] The invention relates to a resource recycling treatment system and a treatment process for high-concentration refractory salt-containing organic wastewater, belonging to the field of wastewater treatment. More specifically, it involves an integrated treatment process of physical treatment, chemical treatment, biological treatment, and membrane advanced treatment for this kind of high-concentration and refractory saline organic wastewater, aiming to use this system on the basis of "nearly zero discharge" Realize the resource recovery and utilization of high-concentration and refractory saline organic wastewater.
