Abstract
The invention belongs to the field of processing of domestic wastewater, and especially relates to a fluidized-bed Fenton system for processing pharmaceutical wastewater. The fluidized-bed Fenton system comprises a drug adding device, a water inlet device, a circulating device, a main reactor and a mud-water neutralization separation device; the drug adding device is provided with three drug adding ports; the main reactor is provided with a liquid discharge port, a return-flow outlet and a return-flow inlet; the circulating device is arranged on the water inlet device; the main reactor is inside provided with a distributor; and the drug adding device, the water inlet device, the circulating device, the main reactor and the mud-water neutralization separation device are in successive connection. The beneficial effects comprise that the CODcr removal rate of the fluidized-bed Fenton system is higher than that of a standard Fenton system by 13.39%, the CODcr removal rate can reach 80% or more, also the mud generation amount can be reduced by about 70%, and the operation cost can be effectively reduced.
Description
Technical field
The invention belongs to water treatment field, particularly relate to a kind of fluid bed Fenton system of Pharmaceutical Wastewater Treatment.
Background technology
Medicine producing wastewater is that a class water-quality constituents is complicated, organic contamination substrate concentration is high, containing the trade effluent, particularly pharmacy wastewater treatment poor compared with the inorganic salt such as perchloride, biodegradability, mostly containing hardly degraded organic substance.
The wastewater treatment of current most of synthesis pharmaceutical enterprise all adopts traditional treatment process based on biochemistry, and contaminated wastewater substrate concentration is high, many to microflora Effec-tive Function influence factor on the one hand, and processing efficiency is low; On the other hand along with environmental requirement improves day by day, wastewater treatment compliance rate declines gradually, and the discharge of giving up of many enterprises is difficult to up to standard.
Summary of the invention
For the problems referred to above that will solve, the invention provides a kind of fluid bed Fenton system of Pharmaceutical Wastewater Treatment.
Technical scheme of the present invention: a kind of fluid bed Fenton system of Pharmaceutical Wastewater Treatment, comprise chemicals dosing plant, comprise water feed apparatus, circulation device, main body reactor and in and device for separating mud and water, described chemicals dosing plant is provided with three dosing mouths, described main reactor is provided with liquid outlet, bypass outlet and backflow import, described circulation device is arranged on described water feed apparatus, divider is provided with in described main body reactor, described chemicals dosing plant, described water feed apparatus, described circulation device, described main body reactor with described in be connected successively with device for separating mud and water.
Be provided with stirring mechanism in described He in device for separating mud and water, in described He below device for separating mud and water, sewage draining exit is set.
Described circulation device adopts single-stage centrifugal pump ring.
Described divider arranges purity quartzite.
Beneficial effect of the present invention is: fluid bed Fenton comparatively standard Fenton exceeds 13.39%, CODcr clearance to CODcr clearance and can reach more than 80%, and sludge output can reduce about 70%, and effectively can lower running cost.

Embodiment
Below in conjunction with accompanying drawing 1, a kind of embodiment of the present invention is explained.
The present invention relates to a kind of fluid bed Fenton system of Pharmaceutical Wastewater Treatment, comprise chemicals dosing plant 1, the water feed apparatus 2 be connected with chemicals dosing plant 1, circulation device 3, the main body reactor 4 be connected with water feed apparatus 2, be connected with main body reactor 4 in and device for separating mud and water 5.Chemicals dosing plant 1, water feed apparatus 2, main body reactor 4 with in be connected successively with device for separating mud and water 5.
Chemicals dosing plant 1 is provided with three dosing mouths.
Main reactor 4 is provided with liquid outlet 6, bypass outlet 7 and backflow import 8, and circulation device 3 is arranged on water feed apparatus 2, is provided with divider 9 in main body reactor 4.
Fluid bed Fenton comparatively standard Fenton exceeds 13.39%, CODcr clearance to CODcr clearance and can reach more than 80%, and sludge output can reduce about 70%, and effectively can lower running cost.
In and device for separating mud and water 5 in be provided with stirring mechanism 10, be conducive to mud-water separation; In and device for separating mud and water 5 below wash water valve 11 is set, for discharging mud.Circulation device 3 adopts peristaltic pump, resistant to corrosion, has good suction capacity, idle running.
Example: first the divider 9 filled by main reactor in 4 loads the purity quartzite with the process of 5%NaOH solution surface, then at Fe
2+/ H
2o
2mol ratio is the pH=3.5 of 2:1, solution, and flooding quantity is carry out growing the grain by chemicals dosing plant 1 and the dosing of water feed apparatus 2 continuum micromeehanics under 1/3 condition of design flooding quantity, and make the crystallisate of the coated enough FeOOH of carrier surface, this phase duration is 15 days.
Start after reactor growing the grain terminates to carry out the wastewater treatment stage, waste water after adjust ph is added to raw water box, with peristaltic pump metering water inlet and dosing, ON cycle device 3 when exceeding main reactor 4 bypass outlet more than 7 to liquid level, during water outlet enters and device for separating mud and water 5 in stirring mechanism 10 with alkali lye and, clear liquid is discharged by upflow tube and the detection that keeps sample, and mud is discharged by wash water valve 11.
Above an example of the present invention has been described in detail, but described content being only preferred embodiment of the present invention, can not being considered to for limiting practical range of the present invention.All equalizations done according to the present patent application scope change and improve, and all should still belong within patent covering scope of the present invention.
