Embodiment Construction

[0022] The present invention will be described in detail below through specific embodiments.

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

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

[0025] (2) First-level aeration: pump the external drainage that has undergone conventional treatment in step (1) into the first-level biological aerated filter through a water delivery pump, and then discharge the water after a first-level aeration treatment; the time for the first-level aeration is 30 minutes, Dissolved oxygen is controlled at 10mg / L. The microbial carrier of the primary aerated biological filter is volcanic rock. Volcanic rock is used as...

Abstract

The invention belongs to the technical field of glucose industrial production, in particular to a method for advanced treatment of glucose industrial wastewater. The advanced treatment method for glucose industrial wastewater comprises the following steps: (1) conventional treatment; (2) primary aeration; (3) micro-ozone treatment; (4) ozone stripping; (5) secondary aeration; ( 6) Filter. This method integrates two-stage aerated biological filters with different fillers and micro-ozone treatment, which greatly reduces the total amount of CODcr in the discharged sewage, and the operating cost does not increase significantly compared with conventional BAF and ozone treatment technologies, and CODcr is degraded. The removal effect is increased by more than 50%, which meets the current national requirements for green environmental protection and clean production of enterprises.

Description

technical field [0001] The invention belongs to the technical field of glucose industrial production, and in particular 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 conventional treatment methods, namely: anaerobic and aerobic integrated technology. 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) using conventional treatment technologies. Contents of the invention [0003] The object of the present invention is to provide an advanced treatment method for glucose industrial wastewater in view of the problem that the prior art does not meet the standard of glucose production industrial wastewater treatment. This method integrates the dual-stage biological aerated filter with diffe...
