Problems solved by technology

Gibberellin wastewater has complex components, is difficult to degrade, and is toxic, teratogenic, and carcinogenic. If it is discharged into the water without treatment, it will cause hypoxia in the receiving water body, aquatic organism toxicity, eutrophication of the water body, farmland soil pollution, and surface drinking water. A series of serious hazards such as safety and was

Embodiment Construction

[0031] The present invention will be further described below in conjunction with the accompanying drawings.

[0032] Example.

[0033] A kind of gibberellin production wastewater treatment process, such as figure 1 Shown, the processing method of gibberellin production waste water, comprises the following steps:

[0034] 1) The raffinate wastewater enters the raffinate adjustment tank to adjust the water quality and quantity, and then pumps it into the coagulation mixing tank through pipelines. Lime is added to the coagulation mixing tank to adjust the pH to 9.5. After mechanical stirring and precipitation, a large amount of sulfate can be removed, and the pretreatment of the raffinate is completed.

[0035] 2) The pretreated raffinate and high-concentration wastewater are mixed in the high-concentration regulating tank to balance and stabilize the water quality and quantity, and then enter the reaction sedimentation tank 1. The reaction sedimentation tank is composed of a rea

Abstract

The invention discloses a treatment method for gibberellin production wastewater, which belongs to the field of environmental protection wastewater treatment. Treatment devices include: raffinate adjustment tank, coagulation stirring tank, high concentration adjustment tank, reaction sedimentation tank, IC, UASB1, comprehensive adjustment tank, UASB2, A/O, micro oxygen tank, sedimentation tank, contact oxidation tank, sewage Mud pool, filter press, filtrate pool; according to the characteristics of gibberellin production wastewater, the present invention performs separate chemical and biological treatment on high-concentration wastewater, mixes it with low-concentration wastewater, and performs biological treatment and mixing again. Condensation and decolorization reaction, process combination design is reasonable, and the effluent fully complies with the national discharge standard. At the same time, the one-time investment and operating costs are reduced, the quality is stable and reliable, the operation management is flexible and convenient, and the maintenance cost is low. On the one hand, it can minimize the remaining sludge and avoid secondary pollution; on the other hand, it is easy to adjust and operate with the change of water quality. , strong adaptability, energy saving and consumption reduction, and zero pollution emission.
