Abstract
The invention relates to a blocky micro-electrolysis stuffing material which is used for treating sewage produced by the low temperature carbonization of coal in the coal chemical and environment engineering field, and a preparation technique thereof. The stuffing material is prepared by the following compositions according to weight ratio: 20 portions to 40 portions of coking coal, 40 portions to 70 portions of iron scraps and 2 portions to 15 portions of bonding agents. The preparation technique comprises the steps that: the coking coal, the iron scraps and the bonding agent are evenly mixed at the temperature of 80 DEG C to 300 DEG C according to the prescribed weight ratio, compressed and molded at the pressure of 5MPa to 15MPa; the molded material is subjected to high-temperature dry distillation for 3 hours to 8 hours at high temperature ranging from 1300 DEG C to 1800 DEG C to obtain the blocky micro-electrolysis stuffing material. Compared with the prior art, the stuffing material does not has hardening and inactivation phenomena, the loading of the stuffing material is convenient and quick, the biodegradability of high-concentration organic sewage which is processed by the stuffing material is significantly improved, and no secondary pollution is caused in the using course of the stuffing material.
Description
Technical field
The present invention relates in a kind of Coal Chemical Industry and the field of environment engineering a kind of block micro-electrolysis stuffing and preparation technology thereof that the sewage that low-temperature pyrolysis in the coal is produced is handled.
Background technology
Along with industrial expansion, the difficulty that high concentration organic sewage is handled is increasing.As everyone knows, biochemical process is that use always, effective, cheap a kind of method of handling organic sewage, but it is not omnipotent.Many industrial sewages are the Pollutant levels height not only, and is difficult to biochemistry, even also is difficult to resolve certainly problem with the anaerobic hydrolysis method.At this moment just need to have adopted various pre-treatments or post-treating method.
Micro electrolysis tech has another name called lasting high-efficiency activated iron bed, continues electrolysis tech in the high reactivity, and this is a kind of electrochemistry sewage preconditioning technique device, and this technology was once handled high density, chemical industry sewage high in salt, that be difficult to biochemical degradation, and effect is very good.
The micro electrolysis tech that adopts mixes the back as micro-electrolysis stuffing with loose shape iron filings and activated carbon powder mostly at present, but such dumped packing hardens easily, passivation, and very fast inefficacy, industrial application value is very low.For this reason, people are seeking always to solve that micro-electrolysis stuffing hardens, the method for passivation, make micro electrolysis tech can really implement industrial application, thereby realize the innoxious pre-treatment of high-concentration sewage.
Summary of the invention
For solving the problem that prior art exists, the objective of the invention is a kind of block micro-electrolysis stuffing and preparation technology thereof, adopting the block efficient micro-electrolysis stuffing of this prepared in use not produce hardens and passivation phenomenon, the block efficient micro-electrolysis stuffing of high concentration organic sewage by preparing, by reduction, oxidizing reaction and follow-up coagulation, absorption and precipitating action, make the polycyclic aromatic hydrocarbons and the heterocyclic organic compound that are difficult to remove obtain removing or changing by biochemical process, present the lipoid substance and the alkane derivative of more easy biochemistry in the water outlet, reach the purpose that significantly improves the high concentration organic sewage biodegradability.
For achieving the above object, the present invention is achieved through the following technical solutions:
A kind of block micro-electrolysis stuffing, this filler be by following compositions by weight ratio make: coking coal 20-40 part, iron filings 40-70 part, binding agent 2-15 part.
Described binding agent is selected from one or more combinations in resol, starch, the tar.
Described preparation technology is: coking coal, iron filings and binding agent mix under 80-300 ℃ of condition to scale, extrusion forming under 5-15MPa pressure, molded material under 1300-1800 ℃ of condition high temperature carbonization 3-8 hour obtains block efficient micro-electrolysis stuffing.
Compared with prior art, the invention has the beneficial effects as follows: filler do not have harden, passivation phenomenon, it is convenient, fast to install filler additional, the high concentration organic sewage biodegradability after handling through this filler significantly improves, and does not produce secondary pollution in the use.
The present invention handles high concentration organic sewage has good effect: COD reduces to 10010mg/L by 20900mg/L, and clearance reaches 47.9%; Chroma removal rate reaches more than 60%.BOD
5/ COD rises to 0.40 of water outlet by 0.06 of former water.
