Problems solved by technology

[0003] Judging from the existing patent materials, although the Chinese patent "Aerobic-anaerobic microbial repeated coupling treatment of sewage new technology (CN200310121766.7)" has a good effect, it will increase the cost of the device to a certain extent, and the aerobic-anaerobic microorganism Anaerobic repeated coupling is not conducive to the absolute anaerobic environment of microorganisms, and the efficiency of biological treatment is not high
The patent "a baffle reactor and its method for treating sewage (CN200610012070)" and the patent "integrat

Embodiment 1

[0045] The comprehensive wastewater produced by a chemical company needs to be treated. The influent concentration before treatment is COD≤6000mg / L, pH 6.5~8.5, SS≤300mg / L, NH 3 -N≤100mg / L, TP≤2.5mg / L, characteristic pollutant concentration chlorobenzenes≤80mg / L. The effluent is required to meet the secondary standard of "Jiangsu Provincial Chemical Industry Discharge Standards for Major Water Pollutants" (DB32 / 939-2006). The effluent indicators require COD≤120mg / L, pH 6.5~8.5, SS≤150mg / L, NH 3 -N≤25mg / L, TP≤1.0mg / L, characteristic pollutant concentration chlorobenzenes≤1.0 mg / L.

[0046] Attached figure 1 Combined process in the combined use of improved Fenton fluidized bed (IFBR), anaerobic expanded granular bed (EGSB) and anaerobic / aerobic baffle reactor (A / OBR) to treat chemical wastewater; including conditioning Tank, improved Fenton fluidized bed, degassing neutralization tank, coagulation sedimentation tank, anaerobic expanded particle bed, anaerobic / aerobic baffle r...

Abstract

The invention provides a method for treating industrial wastewater by a novel combined process. The method adopts a regulating tank, an improved Fenton fluidized bed, a degassing neutralizing tank, a coagulative precipitation tank, an anaerobic expanded granular bed and an anaerobic/aerobic baffled reactor, wherein the units are connected by a water pipe in sequence to treat the industrial wastewater. The method has the beneficial effects that the method is optimized in process and clear and concise in route; the overall COD (chemical oxygen demand) removal rate is not less than 95%; the removal rate of characteristic organic pollutants is not less than 95%; and the method is convenient to operate and manage, is stable in process and is low in investment and operating costs.

Description

technical field [0001] The invention relates to a wastewater treatment method, in particular to a process method for industrial wastewater treatment, and belongs to the technical field of wastewater treatment. Background technique [0002] Industrial wastewater has the characteristics of large changes in water quantity and quality, poor biodegradability, difficult to degrade, and complex and diverse pollutants. Generally, appropriate pretreatment methods are adopted according to the actual wastewater quality, such as flocculation, micro-electrolysis, adsorption, and photocatalysis. , Destroy refractory organic matter in wastewater, improve the biodegradability of wastewater, and then use biological methods, such as ABR, SBR, A / O process, etc., to treat industrial wastewater. At present, domestic and foreign research on industrial wastewater treatment technology also tends to adopt a combination of multiple methods. [0003] Judging from the existing patent materials, althou...
