Background
Along with the rapid development of economy, the urbanization process is accelerated continuously, the urban garbage amount in China is rapidly increased every year, the garbage is treated at present, the simplest and most economical method is landfill treatment, however, landfill treatment can generate garbage percolate which has larger harm and great influence on environment due to improper treatment, the garbage percolate is high-concentration organic wastewater which is difficult to treat and mainly comes from three aspects, namely natural rainfall and runoff in ① landfill sites, water contained in ② garbage, ③ water generated by anaerobic decomposition of microorganisms after the garbage is buried, and the rainfall in the landfill sites is a main source.
At present, the domestic landfill leachate generally adopts a biochemical treatment and membrane treatment technology, and the method can effectively treat the landfill leachate and basically meet the national discharge standard.
However, the treatment method is characterized by large investment and high operating cost, and a large amount of membrane concentrated solution is inevitably generated at the same time, because the concentrated solution has the characteristics of poor biodegradability, high pollutant concentration, high salt content and the like, and is difficult to treat subsequently, most of the concentrated solution is refilled to a landfill at present, but the amount of refractory organics refilled to the landfill is more and more accumulated along with the lapse of time, so that the biodegradability of percolate is more and more poor; on the other hand, the higher the TDS content of the leachate originally, the activity of microorganisms can be reduced, so that the biochemical effect is influenced, meanwhile, the membrane is seriously scaled in the subsequent treatment, the service life of the membrane is reduced, a series of problems such as influence on the quality of effluent water and the like occur, and a vicious circle is formed.
SUMMERY OF THE UTILITY MODEL
The utility model aims at overcoming the not enough of prior art, according to landfill leachate's characteristics, provide the equipment of the advanced treatment after landfill leachate is biochemical, final play water can directly be arranged into municipal pipe network, and its investment running cost is less than other equipment greatly.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a landfill leachate advanced treatment equipment, installs according to the rivers direction order: with the sewage collecting pit of the play water UNICOM of landfill leachate after biochemical, little electrolytic device and middle water tank, the dive pump in the sewage collecting pit export links to each other with little electrolytic device's entry, little electrolytic device include a plurality of electrolysis districts and settling zone, the export of settling zone links to each other with the entry of middle water tank, the export of middle water tank links to each other with the elevator pump entry, the elevator pump export links to each other with the entry of filter, the export of filter links to each other with the product water tank, the bottom discharge port of each settling zone passes through the entry that the hydroextractor was connected to the sludge pump, the mud cake outward transportation that the hydroextractor produced, its pressure filtration liquid gets back to in little electrolytic device.
Further, the micro-electrolysis device is provided with a plurality of micro-electrolysis devices which are connected in sequence, and each micro-electrolysis device comprises an electrolysis area and a precipitation area which are arranged in sequence.
To the main technical effects of the utility model explain as follows: the utility model discloses landfill leachate advanced treatment's technology is to introduce little electrolytic device with the play water after the landfill leachate is biochemical, through the many first catalytic oxidation of multistage electrolysis, degrades the organic matter in the sewage, removes nitrogen and phosphorus, and rethread filter removes the colourity and the suspended solid etc. of sewage, and final play water can directly be discharged into municipal pipe network; the required voltage of the micro-electrolysis device is below 20V, so the energy consumption is extremely low, compared with the biochemical treatment and membrane treatment technology which is generally adopted at present, the utility model has the advantages of no concentrated solution, small occupied area of equipment, low energy consumption, simple operation and maintenance of the equipment and the like.
