Embodiment 1

[0025] A kind of method that Fenton's combination process handles perfume waste water, comprises the following steps:

[0026] ①Put the spice wastewater in the waste water pool through the grid to remove large particles, add polymer flocculant while stirring, the addition amount is 1mg / L, continue to stir for 5 minutes after adding, and place it for 5 hours. During the place, keep the temperature of the waste water at 30°C, filter, remove flocs, and use fragrance wastewater for later use;

[0027] ② Place the pretreated spice wastewater in step ① in an iron-carbon aerated micro-electrolysis reactor with a gas-water ratio of 2:1, react for 1 hour, then transfer the treated spice wastewater into a glass container, and then put it into K 2 C 2 o 4 , 5mmol / LH 2 o 2 , 1mmol / LFeSO 4 , zeolite, sepiolite, stirred for 20min; the pH value was adjusted to 3 and placed in the magnetic field of the electromagnetic machine for 25min, while the irradiation of a 20w ultraviolet lamp was...

Embodiment 2

[0032] A kind of method that Fenton's combination process handles perfume waste water, comprises the following steps:

[0033] ①Put the spice wastewater in the wastewater pool through the grid to remove large particles, add polymer flocculant while stirring, the addition amount is 1.3mg / L, continue to stir for 10min after adding, and place it for 10h. During the period, keep the temperature of the wastewater at 35°C, filter to remove flocs, and use spice wastewater for later use;

[0034] ② Place the pretreated spice wastewater in step ① in an iron-carbon aerated micro-electrolysis reactor with a gas-water ratio of 2:1, react for 1 hour, then transfer the treated spice wastewater into a glass container, and then put it into K 2 C 2 o 4 , 5mmol / LH 2 o 2 , 1mmol / LFeSO 4 , zeolite, sepiolite, stirred for 20min; the pH value was adjusted to 3 and placed in the magnetic field of the electromagnetic machine for 50min, and the irradiation of the ultraviolet lamp of 100w was adop...

Embodiment 3

[0039] A kind of method that Fenton's combination process handles perfume waste water, comprises the following steps:

[0040] ①Put the spice wastewater in the waste water tank through the grid to remove large particles, add polymer flocculant while stirring, the amount of addition is 1.2mg / L, continue to stir for 6 minutes after adding, and place it for 7 hours. During the place, keep the temperature of the waste water at 33°C, filter to remove flocs, and use spice wastewater for later use;

[0041] ② Place the pretreated spice wastewater in step ① in an iron-carbon aerated micro-electrolysis reactor with a gas-water ratio of 2:1, react for 1 hour, then transfer the treated spice wastewater into a glass container, and then put it into K 2 C 2 o 4 , 5mmol / LH 2 o 2 , 1mmol / LFeSO 4 , zeolite, sepiolite, stirred for 20min; the pH value was adjusted to 3 and placed in the magnetic field of the electromagnetic machine for 35min, and the irradiation of the ultraviolet lamp of 8...

Abstract

The invention provides a method for processing perfume wastewater through a Fenton combination process, and relates to the technical field of environmental protection. The perfume wastewater is processed through the flocculation, iron carbon reduction, Fenton oxidization, magnetization, ultraviolet and microorganism processing combination process, the COD and color degree of the perfume wastewaterare greatly reduced, the biodegradability of the perfume wastewater is remarkably improved, and the further processing difficulty of the perfume wastewater is reduced; the investment of process processing units and devices is reduced, and the processing efficiency and effect of the process are improved.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a method for treating spice wastewater by a Fenton combined process. Background technique [0002] Spices are important additives in the fields of food, tobacco, cosmetics, etc., and their sources include the extraction of animal and plant natural flavors from animals and plants and the synthesis of flavors through chemical processes; with the development of the synthetic flavor industry, the synthetic flavor industry has developed into a modern fine chemical industry Another important part of the industry. The wastewater generated during the production of synthetic spices mainly includes esterification washing wastewater, toluene recovery wastewater, rectification and purification wastewater, etc. These wastewaters are characterized by very complex components, large chroma, high toxicity, high COD, and difficult biodegradation, which are typical High concentrat...
