Abstract
The present invention relates to a kind of Fenton oxidation reaction treating devices, including reactor body, water inlet pipe and outlet pipe, wastewater oxidation mechanism and wastewater collection mechanism are equipped in the reactor body, the top of wastewater collection mechanism is arranged in the wastewater oxidation mechanism, the wastewater oxidation mechanism is connected by sludge pipe with wastewater collection mechanism, the wastewater oxidation mechanism includes the electro-catalysis area being set gradually from left to right, electrocatalytic reaction area and exhalant region, the electro-catalysis area, it is sequentially connected between electrocatalytic reaction area and exhalant region logical, the water inlet pipe is connected with electro-catalysis area, the exhalant region is connected with outlet pipe, the outlet pipe is connected by return pipe with water inlet pipe；Electrocatalytic oxidation and Fenton oxidation technology are combined by the present invention, are maximally utilised the useful space of reactor, are simplified the pretreated process flow of Fenton oxidation, reduce operating cost.
Description
Technical field
The present invention relates to a kind of Fenton oxidation reaction treating devices, belong to technical field of sewage.
Background technique
Micro electrolysis tech and Fenton oxidation technology are two kinds of typical wastewater from chemical industry preconditioning techniques, in chemical wastewater treatment
It is often separately or concurrently used in technological design, can reach preferable treatment effect.Micro electrolysis tech and Fenton oxygen are used simultaneously
Usually micro-electrolysis reaction device and Fenton oxidation reaction unit are successively connected when change technology, so that reaching reduces wastewater biological poison
Property and improve the purpose of wastewater biodegradability, create good condition for subsequent biochemical processing.But this design being used in series
Mode needs to connect light electrolysis independent and Fenton oxidation reaction unit according to the process of setting, and configures a system
Column subsidiary conduit and facility, not only operating cost is high for the connection type of this simple superposition, and processing technological flow is tediously long many and diverse, right
Control requires high, it is difficult to make Zero-valent Iron reduction reactor and Fenton oxidation reaction unit while be in optimal operating condition.In addition,
Traditional Fenton process itself is there are some defects, such as iron cement yield are big, and iron ion is lost serious, and iron ion utilization efficiency is low
Under；Fenton iron cement caused by Fenton technology belongs to dangerous solid waste, and subsequent treatment cost is high, and enterprise is difficult to bear.
Nitrogen-containing heterocycle compound, such as pyridine, pyrroles, indoles, quinoline and its derivates.Be widely present in petrochemical industry,
In the waste water of discharges such as food industries, pesticide industry.The water solubility of nitrogen-containing heterocycle compound is much larger than homocyclic compound, enters
It is easily migrated and polluted underground water in soil environment after environment, in addition many nitrogen-containing heterocycle compounds have poison to animal and people
Property, mutagenicity, carcinogenicity, and natural microorganisms is embarrassed to be degraded, thus to the ecosystem and human health generate it is potential and
Long-range harm, it is therefore necessary to which nitrogen-containing heterocycle compound waste water is targetedly handled.And the characteristics of such waste water, is
Salt is high, toxicity is big, biodegradability is poor, complicated component, and conventional biological treatment can not individually work, and be easy to cause in sludge
Poison influences the problems such as system operates normally.Therefore a kind of efficient pretreating process of novel economizer is urgently developed, to reduce this
The toxicity of class waste water simultaneously improves biodegradability, creates good treatment conditions for subsequent biochemical process.Research in recent years is
Show that light electrolysis-Fenton coupling technique is the feasible way realizing nitrogen-containing heterocycle compound waste water high-efficiency and administering.However, fragrant
Workshop section needs to add excessive ferrous sulfate and hydrogen peroxide, adds the disadvantages of reagent cost is high, secondary pollution is big and seriously limits
