Abstract
The utility model provides a waste water disposal device by utilizing ductile cast iron scraps, which comprises a tank body; a support layer is arranged in the tank; an aerator pipe is arranged below the support layer; a water distributing pipe is also arranged below the support layer; a ductile cast iron scrap layer is arranged on the support layer; and a water outlet pipe is communicated with the upper part of the tank. The waste water disposal device is simple and reasonable in structure and takes ductile cast iron scraps as the micro-electrolysis material; the ductile cast iron is featured by a large amount of spherical graphite distributed in the steel matrix and the diameter of the spherical graphite is 0.03-0.10mm; during the process, the majority of the graphite can be preserved in good condition, and the scraps produced are fluffy, coarse, and water and gas permeable; a large number of graphite is distributed in the matrix, so the galvanic cells formed by the graphite are large in number and the disposal effect is strong, thus improving the service performance of the disposal device. The waste water disposal device is applicable for disposing the organic waste water from paper making factories, leather making factories and pesticide production factories.
Description
Technical field
The utility model provides a kind of wastewater treatment equipment, especially a kind of treatment unit of organic waste water.
Background technology
Little electrolysis is applied in wastewater treatment.Used micro-electrolysis material is that gac adds iron filings at present.Because the charcoal absorption ferrous ion after ferrous ion is oxidized, can form shielding on the surface of carbon, makes its degradation.The someone adopted cast iron filing as micro-electrolysis material afterwards, and thought and have cementite (Fe in the cast iron filing
3C), cementite is a negative electrode, and matrix is an anode, generating electrodes reaction thus.And in fact, cementite can not become said negative electrode.This is because cementite is an interstitial compound, and 12 iron atoms, 4 carbon atoms are arranged in each structure cell, and the octahedron that is constituted by 6 iron atoms around the carbon atom wraps up, and carbon atom is formed shielding, thereby can not constitute so-called negative electrode.And what really constitute negative electrode should be graphite in the cast iron.Just the graphite form in the cast iron is strip or sheet, and matrix strength is affected, and a large amount of graphite produce damagedly in the processing, can complete preservation get off seldom, hardens easily in the use and blocks, and degradation is very fast.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of wastewater treatment equipment that utilizes the spheroidal graphite cast iron scrap, to improve its use properties.
The utility model is achieved in that a kind of wastewater treatment equipment that utilizes the spheroidal graphite cast iron scrap, and it has the pond body, in the body of pond supporting layer is arranged, aeration tube is arranged below the supporting layer, also have water distributor below the supporting layer, spheroidal graphite cast iron scrap layer is arranged above the supporting layer, and body top, pond also is communicated with rising pipe.
This wastewater treatment equipment, simple and reasonable, adopted the spheroidal graphite cast iron scrap as micro-electrolysis material, because spheroidal graphite cast iron is a large amount of spherical graphites that distributing in the matrix of steel, its sphere diameter is between 0.03-0.10mm.Most of graphite can more intactly be preserved in the course of processing, the scrap that is produced is fluffy, thick, water-permeable and air permeable, the graphite quantity that distributes in the matrix is many, the quantity that produces galvanic cell is many, treatment effect is strong, thereby improved the use properties of this treatment unit, can be used for the processing of organic waste waters such as paper waste, leather-making waste water, pesticide wastewater.
Description of drawings
Fig. 1 is the synoptic diagram of the utility model structure.
Embodiment
Below in conjunction with description of drawings concrete structure of the present utility model.
As shown in drawings, a kind of wastewater treatment equipment that utilizes the spheroidal graphite cast iron scrap of the utility model, it has pond body 2, supporting layer 5 is arranged in the body of pond, aeration tube 3 is arranged below the supporting layer, also have water distributor 1 below the supporting layer, spheroidal graphite cast iron scrap layer 4 is arranged above the supporting layer, and body top, pond also is communicated with rising pipe 6.
Identical on the concrete structure of water distributor, aeration tube and the existing wastewater treatment equipment no longer described in detail.Can bore a hole on the aeration tube, to improve the aeration effect.Supporting layer is made by permeable, gas-pervious material.The position that the thickness of spheroidal graphite cast iron layer is lower than rising pipe gets final product.
During use, can utilize water pump waste water to be sent in the body of pond through water distributor.Chi Manhou sends into pressurized air through aeration tube in the pond, to add fast response.React after about 2 hours water outlet in the rising pipe.During actual motion, can adopt the mode of the water of being back to back.
In the spheroidal graphite cast iron scrap, graphite is negative electrode, and matrix is an anode.After feeding waste water electrolysis takes place, at anode, iron is oxidized to ferrous ion and enters solution.Ferrous ion has katalysis, can cause C=C key, N=N bond rupture in some compound, makes some macromolecular cpds become micromolecular compound.Ferrous ion can also generate iron sulphide with the sulfide reaction, and reduces the harm of sulfide.Carry out along with electrolytic, stream of electrons is to the C as negative electrode, and near the dissolved oxygen attract electrons negative electrode generates hydroxide radical, and hydroxide radical has stronger oxidisability, can destroy the organism in the waste water and the base that adds lustre to, even can also destroy ring compound.Under the further effect of aerial oxygen, the ferrous iron in the solution is oxidized to ferric iron, and then forms Fe (OH)
3Colloid, this colloid have stronger absorption to be held under the arm and wraps up in function, can be adsorbed on its surface to pollutants in sewage, finally removes with sedimentary form.
