Abstract
The invention provides a method of disposing the sewage by use of the metallurgic filter material, which is metallurgic dual-filter material consisting of water quenching residue and metallurgic dry slag. The filter material is filled into a filtering tower (pool) for disposing sewage. The invention has the advantages of low cost, obvious disposing effect and multiple functions of comprehensively disposing sewage; besides, the removal rates of the suspended solid, the organic and the ammonia nitrogen in the sewage are respectively 60 percent to 86 percent, 40 percent to 70 percent, and 70 percent to over 90 percent, the water quality of yielding water is stable.
Description
One, technical field:
The present invention relates to a kind of sewage water treatment method, also relate to the treatment process of solid waste metallurgical slag simultaneously.
Two, background technology:
Contain a large amount of suspended substances, organism, ammonia nitrogen in the sewage.As not handling, can cause serious harm to environment.Especially urban comprehensive wastewater, industrial sewage more need to handle.Existing treating method is to handle suspended substance with chemical flocculation mostly; Handle organism with flocculation sedimentation; Spent ion exchange resin method processing ammonia nitrogen, there are the characteristics that investment is big, processing is not thorough, use cost is high in these methods.Therefore seek low, the multi-functional novel material of a kind of cost, novel method is very necessary.
Three, summary of the invention:
The object of the present invention is to provide that a kind of cost is low, the method for multi-functional processing sewage with metallurgy slag filter material.The object of the present invention is achieved like this: metallurgy slag filter material is that metallurgical dry slag and the metallurgical Water Quenching Slag of 0.5～1.0mm formed by particle diameter.Method with processing sewage with metallurgy slag filter material of the present invention is: with metallurgical dry slag and metallurgical Water Quenching Slag by volume the ratio of per-cent=1: 1.25～2 pack into and dispose of sewage in the filtrate tower (pond).Metallurgical dry slag is as one-level filtrate filter tower (pond) upper strata of packing into, and metallurgical Water Quenching Slag is as secondary filtrate filter tower (pond) lower floor of packing into.Every metafiltration material lower floor is that the metallurgical dry slag of 4～10mm is made bed course with particle diameter, prevents that filtrate runs off, and helps uniformly distributing water, and its volume is 1/2 of a metallurgical dry slag filtrate volume.
Compared with prior art the present invention has following unusual effect:
1, the metallurgical slag dry slag is meant when metal smelting, the formed lava shape of the molten state slag naturally cooling material that is produced.Have micropore, have and dam, adsorb the function of removing the suspended substance that particle is bigger in the sewage.
2, metallurgical Water Quenching Slag is meant when metal smelting, and the molten state slag that is produced is through the formed particulate material of water fast cooling.Porous and aperture are small, and the bug hole volume is 60%～70% of a cumulative volume, have hold back, adsorption function.
3, the material of metallurgical Water Quenching Slag is formed and have been determined it to have the fundamental unit silica (SiO of anionic frame shape structure
4) tetrahedron and alumina (AlO
4) tetrahedron, the ammonia nitrogen generation ion exchange reaction with in the sewage can be represented by the formula: XZ+NH
4 +-→ NH
4Z+X
+, Z represents the negatively charged ion screen work of aluminosilicate, X represents exchange ion, has the function of removing ammonia nitrogen.
4, metallurgical Water Quenching Slag contains multiple ionogen can form multiple multinuclear complex compound when shrend.The continuous polycondensation of complex compound forms high molecular polymer, and along with the carrying out of polyreaction, the electric charge of polymkeric substance constantly raises, and forms the absorption electrolytic action, and the removal that this helps COD also helps suspensoid impurity in the planar water.
5, subordinate list has been listed and has been adopted the testing data of method of the present invention to three kinds of sewage disposals, and as can be seen from the table, method of the present invention all has certain treatment effect to different classes of sewage.It is effective not only to remove turbidity, but also when removing COD, can play the effect of tangible removal ammonia nitrogen again, has reached multi-functional purpose of disposing of sewage.
6, adopt processing sewage with metallurgy slag filter material, sewage cost of investment, processing cost are reduced greatly, and solved the handling problem of metallurgical slag again.The waterpower flow velocity is 6～15 meters/hour, can obtain tangible suspended substance, organism and ammonia nitrogen removal effect.Remove turbidity 60%～80%, remove COD 40%～70%, remove NH
4 +-N70%～90%, stable effluent quality.
Four, embodiment:
1, the water source is a sanitary sewage
2, selecting two filter towers for use is that water pollutes treatment facility
Structure: two filter towers are mainly formed by filtering tower body, pipeline, back flushing equipment and automatic control device four major parts.Filter tower body inside and be divided into catchment area after water cavity district before the filter, upper filter material layer, lower filter material layer and the filter.The sanitary sewage water-in is provided with upflow tube.
Main technical details:
Specification of equipment: ∮ 2000mm * 2500mm
Single tower processing power 60m
3/ h, waterpower flow velocity V=15m/h
Filtrate: heavy blast furnace slag 440mm, blast furnace water quenching slag 500mm, it is heavy blast furnace slag that particle diameter is 0.5～1.0mm. upper strata filtrate, is used for the bigger suspended substance of granularity in the trap water, and lower floor is that blast furnace water quenching slag is used for holding back, small suspended substance and degraded COD, NH in the absorption, ion exchanged water
4 +-N.Filtrate lower floor establishes padding layer and prevents that filtrate runs off, and helps uniform water distribution, and padding layer is a heavy blast furnace slag, and particle diameter is 4～10mm, and bed course is thick to be 220mm.
Flow direction: for traditional following to stream, promptly streaming falls in gravity, belongs to no press filtration tower.
Influent quality index: turbidity≤50TNU COD≤59mg/l NH
4 +-N≤2.48mg/l
Water-quality guideline behind the drainage: turbidity≤7TNU COD≤22mg/l NH
4 +-N≤1.1mg/l
Filtration cycle:＞20 hours
Back flushing impeller pump: FLG100-125A (power of motor 7.5kw), 30 minutes back flushing filtrates are carried out in the every work of filter tower about 24 hours, rest on pollutent on the filtrate with removal.By the automatic control device back flushing filtrate that automaticallyes switch, filter back water is used in back flushing, filtrate was carried out primary recycling handle in every month.
The effect that metallurgical slag double filtering treating water pollutes: particle diameter is respectively the heavy blast furnace slag of 0.5～1.0mm and the double-layer filter material that blast furnace water quenching slag is formed by 1: 1.25 proportioning, remains on the treating water pollution effects that can reach best in 10m/ hour in filtering velocity.Be turbidity removal rate 86%, COD degradation rate 60%, NH
4 +-N degradation rate 80%, stable effluent quality.
Subordinate list: to the effect table of suspended substance, organism and ammonia nitrogen after the various sewage disposals
