One working principle of the treatment system for the percolate of the household garbage landfill is as follows:
the inlet water firstly enters a homogenizing tank, the percolate passes through the homogenizing tank and then enters a coagulating sedimentation tank, and the percolate passes through FeCl3FeCl is added by an adding system3The inorganic flocculant removes most suspended matters and colloid pollutants in the percolate, reduces COD by about 30 percent and reduces the organic matter load of biochemical reaction.
The effluent of the coagulating sedimentation tank enters an MBR biochemical system for further treatment, and the MBR biochemical system consists of a first-stage denitrification tank, a first-stage nitrification tank and an external ultrafiltration membrane system. The system completely realizes mud-water separation through the external ultrafiltration membrane system, can enrich a large amount of microbial thalli in the biochemical reactor, can reach the sludge concentration of 15-30 g/L, and enhances the biochemical treatment effect. The MBR biochemical system has the advantages of high and stable effluent quality, no bacteria and solid suspended matters, low sludge load and small amount of excess sludge; the reactor is integrated efficiently, and the occupied area is small; pollutants are effectively degraded, and no secondary pollution is caused; easy to realize automatic control, etc. The external ultrafiltration membrane system has a sludge backflow function, namely, ultrafiltration inlet water is subjected to ultrafiltration concentration, purified water is discharged, and the sludge subjected to ultrafiltration concentration flows back to the denitrification tank and is reduced into nitrogen in an anoxic environment to be discharged, so that the aim of denitrification is fulfilled.
in order to guarantee that the quality of water of leaving is up to standard, this system has still set up one-level DTRO system, second grade DTRO system, and second grade DTRO system is used for the further processing to one-level DTRO system permeate liquid, and the end of intaking to first order system is arranged to second grade membrane column concentrate to improve the rate of recovery of system. The two-stage DTRO has higher removal rate, and has higher operating pressure and higher anti-fouling and anti-blocking capacity compared with a roll-type RO system.
The effluent of the primary DTRO concentrated solution is treated by a Fenton oxidation system, a DTNF system, a high-pressure reverse osmosis system and an MVR evaporator (namely a DTZ evaporation system method), the DTNF system and the high-pressure reverse osmosis system further separate and concentrate organic matters and multivalent ions which are easy to foam and scale in the concentrated water, the DTNF concentrated solution is treated by the Fenton oxidation system and then flows back to a biochemical system for percolate treatment to be combined with the percolate, the generated sludge is concentrated and then is dewatered, the concentrated solution of the high-pressure reverse osmosis system enters a triple-effect evaporation system to realize the separation of crystal ions and water, and the evaporation condensed water is mixed with the effluent of the deep treatment of the percolate DTRO membrane and then is discharged after reaching the standard; the water produced by the DTNF system is high-salt-content water with organic matters removed, the high-salt water is subjected to high-pressure reverse osmosis treatment, the produced water is discharged into a clean water tank, the concentrated water is subjected to MVR evaporation treatment to produce monovalent miscellaneous salt, and the monovalent miscellaneous salt is packaged to be improved into high-quality industrial salt. The salinity of the DTNF concentrated water is greatly reduced, the residual organic matters which are difficult to degrade are subjected to fenton oxidation treatment, the biodegradability is improved while the COD is degraded, and the residual organic matters return to the front end of the sewage biochemical treatment for secondary treatment.
the sludge generated in the treatment of the percolate is firstly concentrated by a concentration tank, then enters a sludge dewatering machine for dewatering, the supernatant liquid flows back to a homogenizing tank, and the mud cake is buried for disposal.
