Abstract:
The present application provides a method for treating and recycling organic wastewater, comprising: 1) pretreating the organic wastewater; 2) subjecting an effluent obtained after pretreatment in step 1 to a heterogeneous Fenton reaction with Hangjin clay-supported nano-Fe 3 O 4  as a catalyst, separating the catalyst from a reaction solution after completion of the reaction, and subjecting the reaction solution to a reaction to remove COD; 3) subjecting an effluent obtained in step 2 to an anaerobic ammonia oxidation reaction to denitrify by ammonia nitrogen reacting with nitrite nitrogen; 4) subjecting an effluent obtained in step 3 to an aerobic microbial decomposition and ultrafiltration membrane separation to remove COD and ammonia nitrogen; 5) filtering an effluent obtained in step 4 to remove large particles; 6) supplying an effluent obtained in step 5 to an RO system, and using an effluent from the RO system as circulating cooling water, and subjecting concentrated water from the RO system to a softening treatment; and 7) supplying softened concentrated water obtained in step 6 to an NF system for treatment, evaporating an effluent obtained after the treatment to recover NaCl, and returning a resulting concentrated water to step 1. The present application also provides a device for implementing the method for treating and recycling an organic wastewater.

Claim (Index 4):
The method according to  claim 1 , wherein the nitrite nitrogen in step 3 is derived from the nitrosation of ammonia nitrogen and the reduction of nitrate nitrogen by a three-electrode system.
