Description

A kind of Fenton one fluid bed

Technical field

This utility model is related to sewage treatment equipment field, particularly a kind of Fenton one fluid bed.

Background technology

At present, in the waste water after biotechnology process, many hardly degraded organic substances are there typically remain, causes water outlet water Matter is not up to standard, especially the wastewater from chemical industry such as printing and dyeing, papermaking, nitrification.And requirement of the country to water process is more and more stricter, recycled water Use increasingly paid attention to, therefore, it is very necessary for the advanced treating of biotechnology processed waste water.Fenton reagent due to The hydroxyl radical free radical of generation has Strong oxdiative ability, has good treatment effect for these Recalcitrant chemicals：While by In Fenton technical operation it is simple, cost of investment is low, treatment effect is good and is widely used.However, traditional Fenton is urged Agent is dissolved in the water with ionic formses, and as sewage current are lost in, Fenton processes the whole addition ionic type metal of sewage Catalyst, catalyst consumption amount is big.In sewage whole process is processed, the time of sewage, oxidant and catalyst reaction is shorter, oxygen Agent is not especially desirable to wastewater treatment efficiency to be fully used.

Utility model content

This utility model is intended at least to solve to a certain extent one of above-mentioned technical problem in correlation technique.For this purpose, The utility model proposes it is a kind of can improve catalyst and oxidant utilization, while improving the Fenton one of sewage treatment capacity Fluid bed.

This utility model solves the technical scheme that its technical problem adopted：

A kind of Fenton one fluid bed, including reactor tank body, are provided with water inlet and outlet, institute on reactor tank body State reactor tank body and be divided into pre-mix zone, filler set area and solid-liquid displacement zone from bottom to top, the solid-liquid displacement zone top is Effluent weir, is provided with overflow area between the effluent weir and reactor tank body, reactor tank is provided with vitro and the overflow area The outer circulation pipeline of connection.

Used as the improvement of above-mentioned technical proposal, the pre-mix zone of stating is separated with filler set area by filter plate.

As the further improvement of above-mentioned technical proposal, multiple filters are mounted on the filter plate.

Further, set catalyst filling on the filter plate.

Further, it is provided with swash plate in the solid-liquid displacement zone.

The beneficial effects of the utility model are：This utility model adopts integration apparatus form, has to equipment from technique Ratio of height to diameter is required, to meet upflow velocity.Therefore equipment overall compact, floor space is little；The blood circulation of fluid bed will react The multiple excessively stream catalyst surface of device inside waste water, so as to substantially increase the reaction efficiency of oxidant and dirty water pollutant, carries The utilization rate and the clearance of pollutant of high oxidant；Avoid the loss of catalyst.Only need to periodically give a small amount of supplement i.e. Can, compare and the consumption of catalyst is greatly reduced for traditional handicraft, while decreasing the yield of iron containing sludge.

Description of the drawings

This utility model is further illustrated with reference to the accompanying drawings and examples.

Fig. 1 is this utility model example structure schematic diagram.

Specific embodiment

With reference to Fig. 1, a kind of Fenton one fluid bed of the present utility model, including reactor tank body 1, on reactor tank body 1 Water inlet 2 and outlet 3 are provided with, the reactor tank body 1 is divided into from bottom to top pre-mix zone 4, filler set area 5 and solid-liquid Disengagement zone 6, the top of the solid-liquid displacement zone 6 is effluent weir 7, and between the effluent weir 7 and reactor tank body 1 overflow area is provided with 8, effluent weir 7 is loop configuration, and outlet pipe 3 is connected with overflow area 8, and overflow area 8 can be annular, or semi-circular, instead Answer and be provided with the outer circulation pipeline 9 connected with the overflow area 8 outside device tank body 1, it is preferred that be provided with solid-liquid displacement zone 6 tiltedly Plate 13, its effect is float in barrier flowing water, prevents float from floating up to outlet.

Further, the pre-mix zone 4 of stating is separated with filler set area 5 by filter plate 10, is pacified on the filter plate 10 Equipped with multiple filters 11, set catalyst filling 12 on the filter plate 10.

Reactor tank body 1 is gone out to overflow area 8 through the sewage of preliminary treatment by effluent weir 7, and a part is from outlet 3 Discharge, another part is back to tank body lower end by outer circulation pipeline 9, and has taken back a part of oxidant.Meanwhile, the dirt of backflow Pollutant in the sewage that water is input into water inlet 2 are diluted, and improve the reaction efficiency of pollutant, oxidant, catalyst Using more abundant.Oxidant and sewage repeatedly flow through catalyst surface through internal circulation pump, so as to catalysis greatly reduces The consumption of agent, reduces the yield of iron containing sludge, improves the utilization rate of oxidant, enhances the stability of system, improves The degradation efficiency of dirty water pollutant.For more traditional Fenton handling process, direct cost reduces 1/3.

It is composite waste of the erythromycin wastewater after Aerobic Process for Treatment that this Fenton fluid bed workshop section processes waste water, and its COD is 500m³/ d, but its B/C much ＜ 0.1, belong to non-renewableization waste water.In the case of the limited addition of oxidant, pass through The COD of this utility model processed waste water is reduced to 300, but B/C is than the level of raising to ＞ 0.4, then by simple biochemical Handling process can be by wastewater treatment to qualified discharge level.This utility model can degrade COD meeting traditional Fenton technology, Can improve on the basis of B/C ratios again, also reduce operating cost, be that blowdown enterprise brings practicable waste water control skill Art

Above concrete structure and sized data are that preferred embodiment of the present utility model is illustrated, but this reality The embodiment is not limited to new creation, those of ordinary skill in the art are in the premise without prejudice to this utility model spirit A variety of equivalent variations or replacement can be also made down, and the deformation or replacement of these equivalents are all contained in the application claim and are limited In fixed scope.
