Description
Technical field:
The invention belongs to a kind of treatment process of underground sewage, particularly the method for the liquid concentrator of drop liquid generation is oozed in treating refuse.
Background technology:
Landfill by domestic and international widespread use, at present has MSW about 90% with landfill method to handle in China as a kind of MSW (rubbish) processing mode.In municipal wastes landfill process, contained pollutent will be with the moisture stripping in the rubbish, and forms percolate with rainfall, runoff etc.Percolate is the very strong high concentrated organic wastewater of a kind of pollution, and percolate can pollute underground water, surface water and refuse landfill surrounding environment, threatens tap water and industrial or agricultural water water source, and groundwater quality is polluted and the forfeiture utility value.
The Pollutant levels of percolate are high, and variation range is big, and this is that other sewage is incomparable, thereby brought very big difficulty for the processing and the process choice of percolate.At present the processing scheme to percolate mainly contains two big types: one type be with percolate after certain pre-treatment or directly enter the municipal sewage plant and merge processing; Another kind of is that percolate is carried out individual curing.Though it is the simplest to merge processing scheme, also belong to feasiblely on the technology, be not to be the method for generally using.Usually landfill yard is positioned at area, remote mountain valley away from the city, and the remote handling charges of percolate is higher and uneconomical.Because peculiar water quality of percolate and variation characteristics thereof are prone to cause the impact to the municipal sewage plant, the normal operation of influence even destruction municipal sewage plant, independently handle percolate this moment is necessary.
In the processing of percolate has with two big types of processing schemes outside the venue.Concrete scheme has following several kinds: 1, directly enter the municipal sewage plant and merge processing; The common landfill yard of this method is positioned at area, remote mountain valley away from the city, the remote handling charges of percolate is higher and uneconomical.Because peculiar water quality of percolate and variation characteristics thereof are prone to cause the impact to the municipal sewage plant, the normal operation of influence even destruction municipal sewage plant.2, percolate sprays to the circulation of landfill yard and handles; Not enough below this technology exists: (1) can not be eliminated percolate fully.Because the diafiltration liquid measure of spraying or recharging receives the restriction of landfill yard characteristic, thereby still has most of percolate must efflux processing; (2) still need handle and to discharge through the percolate after the spray cycle, especially because the circulation of percolate in waste layer causes its NH
3-N constantly accumulates, even finally makes its concentration far above its concentration in acyclic percolate.3, after necessary pre-treatment, import the municipal sewage plant and merge processing; This method is based on and alleviates when carrying out direct combination treatment a kind of the inside and outside associating processing scheme that deleterious poisonous substance in the percolate is taked the impact harm of municipal sewage plant.Percolate is at first handled through the pre-treatment facility of being located in the landfill yard; With remove pollution substance such as heavy metal ion, ammonia nitrogen, colourity and SS in the percolate or through anaerobic treatment to improve its biodegradability, to reduce load, be to merge to handle normal operation and create good condition.But this method is difficult to effectively remove NH for the percolate of the landfill yard of youth
3-N.Thereby maybe must carry out pre-treatment or consider adopt the A of tool biological denitrificaion function
2/ O (or A/O) treatment system could be effectively with its removal.4, build an independently interior complete treatment system; But build an interior independent processing system and have some difficulties: the water quality of (1) percolate has bigger variation with the variation at landfill yard age, when considering that it is handled, must adopt capacity of resisting impact load and adaptable process system.Landfill percolate is suitable for the employing biological treatment for " youth ", and to " old " landfill percolate, then should adopt materialization to handle.Thereby its processing technological flow operational administrative is complicated, and last effect is difficult to obtain secular assurance; (2) often contain the NH of contents of many kinds of heavy metal ion and higher concentration in the percolate
3-N need to adopt method such as chemistry in addition necessary pre-treatment and even aftertreatment, so its running expense is higher; (3) (C: N: P) often imbalance, its outstanding feature are that nitrogen content is too high not enough with phosphorus content to the nutritive props in the percolate, need in treating processes, cut down nitrogen and additional necessary phosphorus; (4) output of landfill percolate is compared often lessly with municipal sewage plant's treatment scale, thereby small-scale treatment system is set separately aspect running expense, lacks meliority economically.
In addition, the bioremediation that also has some percolates at present: 1, aerobic biological process for treating.2, anaerobic biological treatment method.3, anaerobic-aerobic combination treatment method.4, oxidation pond treatment process.
In sum, the treatment process of garbage loading embeading percolation liquid is diversified, but method therefor all is based on common wastewater treatment method or improves one's methods and develop out.Because the property complicated and changeable of garbage loading embeading percolation liquid water quality and quantity when selecting the treatment process of percolate, is handled on the basis of percolate character fully understanding; Not only to consider the treatment effect of this technology, also will consider handiness and flexibility that this process method changes water quality and quantity percolate.Generally should pay the utmost attention to anti impulsion load ability and adaptable technology, select to satisfy the method for processing requirements again, require to propose scheme and technology targetedly with economic technology as the case may be.
