Description
Technical Field
The invention belongs to the technical field of environmental protection, and particularly relates to a biological and ecological cooperative treatment method for leachate of a garbage transfer station.
Background
The artificial wetland is to artificially plant plants in a substrate by simulating a natural wetland system and distribute sewage on the substrate. The sewage flows through the wetland and is treated into clean water under various actions of plants, substrates, and microorganisms attached to the substrates, such as physical, chemical, and biological actions. The artificial wetland is developed from the 70 th century as an ecological and friendly water treatment technology, shows great potential while continuously developing and innovating the technology, and is widely used for treating black and odorous eutrophic water bodies, industrial wastewater, livestock and poultry breeding wastewater, printing and dyeing wastewater, food sewage and garbage percolate at present.
The landfill leachate refers to high-concentration organic wastewater leached in a landfill process due to rainwater and underground water in a landfill. The leachate of the refuse transfer station is one of the leachate of refuse, and generally refers to mixed wastewater formed by fresh leachate, transfer station flushing wastewater, worker domestic wastewater and the like generated in the refuse compression process in the refuse transfer station.
The garbage transfer station is used as a connection point for the scattered recovery and the centralized treatment of garbage (large garbage landfills, incineration stations and the like), the garbage transfer amount is increased year by year due to the national economic development and the improvement of the national living standard, and the generated transfer station percolate is also increased year by year.
The leachate of the garbage transfer station has the following characteristics: 1. water quantity is as follows: the water quantity of a single transfer station is less and is scattered along with the distribution of the transfer stations, and because the transfer stations have peak working hours, the water quantity fluctuation in one day is large, and the influence of seasons is large. 2. Water quality: because the service areas of all the garbage transfer stations are different, the water quality difference is large, the components are complex, the conventional water quality indexes such as COD, ammonia nitrogen and total phosphorus can not reach the treatment standard of the municipal sewer nano-tube, and the conventional water quality indexes often contain heavy metals, PPCPs, antibiotics, resistance genes and the like. Because the total amount of the landfill leachate is huge and is scattered in all corners of a city, if the landfill leachate can not be properly treated, on one hand, the odor generated by the landfill leachate can cause the environment near the landfill leachate to be poor, and on the other hand, the direct discharge of the landfill leachate can pollute the underground water; or directly into municipal sewage in a city may affect the normal operation of sewage treatment plants at the end of the sewage. Therefore, the proper treatment of the leachate of the garbage transfer station is a necessary way and an important guarantee for building a novel green city.
The existing artificial wetland system is often used for treating the percolate of the refuse landfill by following the treatment method, is not suitable for the characteristics of the percolate of a refuse transfer station, and has the defects of low treatment efficiency, large occupied area, high construction cost, inconvenient operation and maintenance management and the like.

The present invention is further described with reference to the following drawings and specific examples so that those skilled in the art can better understand the present invention and can practice the present invention, but the examples are not intended to limit the present invention.
Example 1
As shown in fig. 1 and 2, the constructed wetland system for treating leachate of the garbage transfer station comprises a constructed wetland tank body 1, a water distribution pipe 2, a plant layer 5, a mixed matrix layer 3, a gravel matrix layer 4, a vent pipe 6 and a water outlet pipe 7; plant layer 5, mixed matrix layer 3 and gravel matrix layer 4 set gradually in constructed wetland cell body 1 from last to down, water distributor 2 sets up on mixed matrix layer 3, outlet pipe 7 sets up in gravel matrix layer 4, breather pipe 6 sets up on mixed matrix layer 3.
The mixed matrix layer 3 comprises river sand, activated carbon and manganese powder, and the mass ratio of the river sand to the activated carbon to the manganese powder is 1: 0.8-1.2: 0.8-1.2, the river sand has the grain diameter of 500-800 mu m, the activated carbon has the grain diameter of 200 meshes, the manganese powder has the grain diameter of 100 meshes, and the thickness of the mixed matrix layer 3 is 1-2 m. The manganese powder has strong oxidation effect on various pollutants, has certain adsorption capacity and catalytic capacity, has great removal potential on the pollutants and can keep activity for a long time; the activated carbon can adsorb pollutants such as organic matters, ammonia nitrogen, phosphorus and the like, and the huge specific surface area can provide living environment for microorganisms in the artificial wetland, so that the microorganisms inhabit the activated carbon and further remove the pollutants to achieve the effect of activating the activated carbon; in addition, the river sand plays a certain role in stabilizing the pH value of the wetland system so as to be suitable for the survival of microorganisms. River sand-activated carbon-manganese powder is used as a mixed matrix, so that the constructed wetland system disclosed by the invention has outstanding effects of adsorbing, oxidizing and catalyzing and converting pollutants.
The mixed matrix layer 3 is added with a compound microbial agent, and the compound microbial agent is prepared by mixing anaerobic ammonia oxidation bacteria, nitrobacteria, denitrifying bacillus, bacillus subtilis, saccharomycetes, lactic acid bacteria and flocculating bacteria according to the ratio of 5-10: 2-10: 1-6: 1-5: 1-3: 1-3: 1 by weight ratio.
The gravel matrix layer 4 comprises gravel, the particle size of the gravel ranges from 10 to 100 meshes, and the thickness of the gravel matrix layer 4 ranges from 0.1 to 0.5 m.
The plant layer 5 comprises roots of vanilla grass. The vetiver grass has good tolerance to landfill leachate, and the wetland has a large and fine root system and a strong capability of absorbing N, P, so that the effect of removing pollutants is further enhanced. In addition, when the pollutant load of the leachate of the garbage transfer station is low due to the fact that the proportion of flushing water is too high, planting of other artificial wetland plants and matching of vetiver grass can be considered to further improve the greening effect of the leachate.
The water distribution pipes 2 are round water distribution pipes which are formed by a main pipe penetrating through the constructed wetland tank body and branch pipes extending to all corners of the constructed wetland tank body, and the water outlet pipes 7 are round water outlet pipes which are formed by a main pipe penetrating through the constructed wetland tank body and branch pipes extending to all corners of the constructed wetland tank body. The water distribution pipe and the water outlet pipe ensure the uniformity of water distribution and drainage and further improve the treatment efficiency.
The artificial wetland system also comprises a water outlet regulator 8 for regulating the height of the outlet water, and the water outlet regulator 8 is connected with the water outlet pipe 7. The outlet water regulator 8 regulates the height of the tail end of the outlet pipe, and can set a submerged area and a non-submerged area in the mixed matrix layer 3. In the upper non-submerged area, because the water distribution system runs by tides, an aerobic-anaerobic environment is continuously formed in the area, so that the removal effect of the wetland on pollutants is enhanced, the nitrification is enhanced, the denitrification is limited to a certain extent, and a large amount of NO is enriched in the effluent of the wetland 3- Limiting the complete removal of TN. In the lower submerged area, the flooding ensures that the wetland is always in an anaerobic environment, enhances the denitrification of the wetland, enlarges the migration and transformation paths of nitrogen in the wetland and promotes TN to be thoroughly removed.
An overflow port 11 is arranged at the upper part of the artificial wetland tank body 1. The overflow port 11 is used for ensuring that the wetland system is not impacted and can still normally operate subsequently under special conditions of heavy rain, high hydraulic load and the like.
The artificial wetland system also comprises a back washing device 9, and the back washing device 9 is connected with the water outlet pipe 7. The backwashing device 9 pumps the outlet water or tap water from the bottom of the wetland through the outlet pipe by an external water pump, and discharges the dirt and the sediment in the wetland through the overflow port 11 along with the water flow by mutual friction among the fillers, thereby achieving the effect of cleaning the substrate of the artificial wetland.
The constructed wetland system of the invention operates in an 'intermittent water distribution and continuous water outlet' mode, leachate of a garbage transfer station is intermittently pumped into an constructed wetland tank body 1 and distributed by a water distribution pipe 2, then water flows vertically and freely flow downwards from the surface, the water flows sequentially flow through a plant layer 5, a mixed matrix layer 3 and a gravel matrix layer 4, and finally is collected by a water outlet pipe 7 in the gravel matrix layer 4 and then continuously discharged out of the constructed wetland tank body 1 and finally discharged from a water outlet 10. Adjusting the water outlet height of the artificial wetland tank body 1 to form a submerged area at the lower part of the mixed matrix layer 3, forming a non-submerged area at the upper part of the mixed matrix layer 3, and introducing air into the upper part of the mixed matrix layer 3. Because the non-submerged area is intermittently contacted with the air, an aerobic-anaerobic environment is continuously formed in the non-submerged area, and the aerobic nitrification of microorganisms is generated; an anaerobic environment is formed in the submerged area, and the anaerobic denitrification of microorganisms occurs.
