Description
Technical Field
The utility model belongs to the technical field of sewage treatment device, concretely relates to landfill leachate handles retrieval and utilization device.
Background
Along with the improvement of the living standard of human beings, more and more garbage is generated in daily life, and along with the increase of garbage landfill plants, however, the landfill plants with the largest pollution are polluted leachate, if the leachate is not treated and does not reach the standard, the quality of local underground water is seriously influenced, and the landfill leachate in China has the characteristics of high COD (chemical oxygen demand), high ammonia nitrogen content, complex components, poor biodegradability, large fluctuation of water quality and water quantity and the like. At present, most of landfill leachate is treated by adopting a 'biological and membrane treatment' process, effluent can reach the discharge standard, but a membrane treatment concentrated solution in the 'biological and membrane treatment' process is lifted to a landfill site through a recharging pump, the salt content in the landfill leachate is higher and higher along with longer and longer running time, the load of a subsequent membrane treatment system is larger and larger, the treatment capacity of the membrane treatment system is reduced, the service life of a membrane is shortened, and the treatment capacity and the water quality cannot meet the requirements. Although the research and application of the landfill leachate treatment technology are in need.
The basic process principle of membrane separation is relatively simple. In the process of filtration, the feed liquid is pressurized by a pump, the feed liquid flows along the surface of the filter membrane at a certain flow rate, substance molecules with molecular weight larger than the molecular weight intercepted by the membrane do not permeate the membrane and flow back to the charging tank, and substances or molecules with molecular weight smaller than the molecular weight intercepted by the membrane permeate the membrane to form dialysate. Therefore, the membrane system has two outlets, namely a reflux liquid (concentrated liquid) outlet and a dialysate outlet. Per unit membrane area (m) per unit time (Hr)2) The amount of dialysate flow (L) is called membrane flux (LMH), i.e. filtration rate. Factors affecting membrane flux are: temperature, pressure, solids content (TDS), ionic concentration, viscosity, and the like. The membrane separation process is a pure physical process and has the characteristics of five-spice change, energy conservation, small volume, detachability and the like, so that the membrane is widely applied to fermentation, pharmacy, plant extraction, chemical engineering, water treatment process and environmental protection industries. For organic matters with different compositions, different membranes are selected according to the molecular weight of the organic matters, and a proper membrane is selectedThe process can reach the best membrane flux and rejection rate, raise production yield and reduce investment and operation cost.
The advanced oxidation treatment is to mix ferrous sulfate and hydrogen peroxide according to a certain proportion and add the mixture into a concentrated solution treatment system, and destroy organic matter molecules by using the strong oxidizing property of the mixture to decompose macromolecular organic matters which are difficult to degrade in percolate into micromolecular organic matters which are easy to degrade, so that the subsequent biochemical treatment effect is improved, and partial organic matters are directly oxidized into CO2And H2O, while Fe2+Is oxidized into Fe3+And carrying out coagulating sedimentation by adjusting pH value to further remove organic matters. Fenton is used as a strong oxidant, can directly remove refractory organic matters and improve the biodegradability of wastewater, and the process is combined with the biological aerated filter process, so that the treatment efficiency is high, and the effluent quality is stable.
