Embodiment Construction

[0022] Hereinafter, the present invention will be described in detail through specific embodiments.

[0023] A method for advanced treatment of glucose industrial wastewater, including the following steps:

[0024] (1) Conventional treatment: pass the glucose industrial wastewater through an EGSB reactor; A / O aerobic and sedimentation treatment to obtain external drainage; after conventional processing, the biodegradability is poor, and BOD5 / CODcr≤0.2 is difficult to degrade Range, where CODcr is about 60mg / L;

[0025] (2) Primary aeration: the external drainage that has undergone the conventional treatment in step (1) is pumped into the primary aeration biological filter through a water pump, and the water is discharged after one aeration treatment; the first aeration time is 30 minutes, Dissolved oxygen is controlled at 10mg / L. The microbial carrier of the primary biological aerated filter is volcanic rock. Using volcanic rock as the microbial carrier of the primary aerated biol...

Abstract

The invention belongs to the technical field of industrial glucose production, and particularly relates to a deep treatment method for industrial glucose wastewater. The deep treatment method for industrial glucose wastewater comprises the following steps of 1, conventional treatment, 2, primary aeration, 3, micro ozone treatment, 4, ozone air stripping, 5, secondary aeration and 6 filtering. According to the method, primary and secondary aeration biological filters with different fillers and micro ozone treatment are used integrally, so that the total amount of COD cr in drained sewage is greatly decreased, the operation cost is not obviously increased compared with conventional BAF and ozone treatment technologies, the COD cr degradation and removal effect is improved by more than 50%, and the requirement for environment protection and clean production of enterprises in current China is met.

Description

Technical field [0001] The invention belongs to the technical field of glucose industrial production, and specifically relates to a method for advanced treatment of glucose industrial wastewater. Background technique [0002] At present, the treatment technologies used in domestic glucose production industrial wastewater are all conventional treatment methods, namely: anaerobic and aerobic integrated technologies. With the increasingly stringent national environmental protection requirements, it has been difficult to meet the industrial wastewater discharge standard (CODcr<60mg / L or 100mg / L) by using conventional treatment technologies. Summary of the invention [0003] The purpose of the present invention is to provide a method for advanced treatment of glucose industrial wastewater in view of the problem that the prior art does not meet the standard for the treatment of industrial wastewater from glucose production. This method integrates two-stage biological aerated filter ...
