Description
Technical field
The present invention relates to method for treating garbage percolation liquid, specifically, is related to one kind and passes through reverse osmosis for percolate
The method that permeable membrane, NF membrane or concentrate caused by other filtering embrane method processing are handled.
Background technology
Country promulgates within 2008《Household refuse landfill sites contamination control standard》(GB16889-2008), to garbage filter
The processing of liquid proposes higher requirement, nowadays handles percolate and uses NF, RO membrane treatment process more.Rubbish percolation liquid membrane
Filter concentration liquid is the raffinate that percolate retains after biodegradation through NF films (or RO films), typically without biochemical
Property, Main Ingredients and Appearance is humus material, and in brownish black, COD is very high, and contains substantial amounts of inorganic ions, and TDS is 20000
Between~60000mg/L, generally between 1000~5000mg/L, ammonia nitrogen concentration is COD in 100~1000mg/L, electrical conductivity
40000~50000us/cm.
The volume of film-filter concentration liquid accounts for the 20%~30% of percolate stoste volume.Because concentrate contains various difficulties
The organic and inorganic pollution of degraded, directly discharge may pollute to generations such as soil, surface water, oceans；If it is discharged into municipal administration
Sewage disposal system, growth of the too high total dissolved solid to activated sludge are also unfavorable.Therefore for the production of reduction concentrate
The research that amount, concentrate continue with is necessary.
Main processing method is used to have at present：Recharge, evaporation drying, solidification, burning etc..By embrane method Concentrated liquid recharge
To refuse landfill, garbage storing hole or percolate storage pool, long-term circulation can cause the tired of salt and organic matter in percolate
Product, so as to cause biochemical treatment system effect to be deteriorated, increase the burden and expense of embrane method system operation.It is by embrane method to evaporate drying
Soluble solids is separated from water in concentrate, requires high to evaporator corrosion resistance, and energy consumption is big, and operating cost is higher.This
Outside, the partial organic substances in embrane method concentrate are volatile, and evaporation process, which is dealt with improperly, easily causes secondary pollution.Curing process is profit
Sludge carries out curing process to embrane method concentrate caused by flying dust or sewage disposal, then transports the residue of desiccation to rubbish
Landfill yard carries out innoxious landfill.Because the garbage disposal after solidification causes processing cost to increase, to the processing of embrane method concentrate
During need to account for reference to soot actual conditions and economic analysis.High-level oxidation technology is current processing garbage filter
The proper treatment technology of concentrated liquor, the speed of high-level oxidation technology degradation of organic substances is very fast, such as O3/ UV systems and O3/
H2O2System oxidation degradation process, and the intermediate product in oxidizing process can continue same hydroxyl radical reaction, until last
Carbon dioxide and water are oxidized to completely.
But because rubbish percolation liquid membrane concentrate pollutant concentration is too high, if using single chemical oxidization method, its
Operating cost is too high.If using the relatively low biological treatment of operating cost, the biodegradability of pollutant is again very low.If adopt
It is difficult to solve again with membrane treatment process, the problem of fouling membrane.Therefore, percolate embrane method concentrate is badly in need of one kind simply at present
Effectively, the deep treatment method for the embrane method concentrate that energy consumption is low, operating cost is low.

Hydrochlorate, denitrogenation are very difficult, it is difficult to reach discharge standard.Aerobic MBR is low to the removal efficiency of nitrate nitrogen, and this project uses
Anaerobism MBR has fabulous denitrification efficiency, can not only be carried out using small organic molecule caused by ozone oxidation as carbon source
Denitrogenation, Anammox reaction denitrogenation can also occur with remaining ammonia nitrogen under anaerobic, the total of concentrate can be significantly reduced
It is nitrogen discharged.
4) present invention pretreatment uses complex coagulation depositing technology, hardness and calcium ions and magnesium ions can be being removed, in waste water
Organic matter also have significant removal effect.The organic loading of Anaerobic Treatment can be greatly reduced, while prevent anaerobism MBR productions
Raw inorganic matter fouling membrane.
5) invention post processing uses nanofiltration and pressure contact oxidation combination of reactors technique.Nanofiltration technique can further drop
Organic matter in low waste water, it is ensured that stable water outlet is up to standard.Meanwhile in order to which the salt content in reduction system, this project select nanofiltration
As post processing secondary filter.Nanofiltration has preferable permeability to monovalent ion, and secondary filter is carried out not using nanofiltration technique
The salt content of concentrate can be significantly improved, so that the salinity of biochemical system keeps stable.
6) in order to further lift the effect of water outlet, the end of handling process is provided with pressure contact oxidation reactor, entered
One step improves effluent quality.Because the organic matter in NF membrane permeate is small molecule, biodegradability is good.In pressure contact oxygen
Change in reactor, high pressure is formed by intake pump, the transport resistance of oxygen reduces under high pressure, and oxygen is to microorganism in mixed liquor air
The efficiency of transfer greatly enhances, and can improve the activated sludge concentration in reactor, makes in reactor that biomembrane character is fluffy, is not easy
Conglomeration, activity are remarkably reinforced.Be advantageous to the propagation of active sludge microorganism and the degraded of organic matter.So as to ensure aqueous concentration very
It is low.Filter layer is provided with inside pressure contact oxidation device, stable effluent quality is secure.
