Above patent main purpose is organic matter, the ammonia nitrogen utilizing in diafiltration technology degrading waste water, and material is mainly cinder, sand, gravel particle thing class, as microbe carrier, to reduce cost of sewage disposal.
In wastewater treatment " zero-emission " process, high-concentration salt-containing wastewater after evaporation and concentration conventionally adopts thermal crystalline, naturally the method such as dries, thermal evaporation crystallization need to consume a large amount of energy, and the crystallization of carnallite easily causes equipment scaling, brings certain difficulty to operation continuously.The evaporation pond that dry area in north china adopts, at natural evaporation in winter weak effect, is difficult to reach the object of mummification.
Summary of the invention
Large for moisture solid waste heat dehydration energy consumption, naturally dry factors such as being subject to weather effect, the present invention has invented a kind of continuous filter, collects the moisture of moisture solid waste, by the further mummification of moisture solid waste, to reach object concentrated, mummification solid waste.
The invention provides a kind of continuous filter for the moisture solid waste of mummification, the whole antiseepage in described continuous filter.The construction of described continuous filter is according to relative national standards and enforcement of regulations antiseepage (< < hazard waste landfill pollution control criterion > > (GB18598-2001), < < household garbage field landfill pollutes control criterion > > (GB 16889), < < domestic waste field Sanitary Landfill Technology standard > > (CJJ17)).
Described continuous filter perimeter walls adopts concrete frame and seepage brick structure, fills out seepage brick between framework; Seepage brick is laid in bottom, described continuous filter, and bottom seepage brick laying depth is 15～40 centimeters; Between described bottom and periphery seepage brick, through joint filling, process; The bottom of described bottom seepage brick is lined with 10～30 centimeters of infiltration collection materials;
Described continuous filter periphery is provided with leachate collection ditch; Described leachate collection ditch liquid level absolute altitude pushes up lower than bottom seepage brick; Described continuous filter connects the collecting-tank for the percolate after collection and treatment.
Described continuous filter can independently be used in separate room, also can lattice series connection use.
When the lattice series connection of described continuous filter is used, from the direction of water, every lattice liquid level discrepancy in elevation is more than 0.2 meter.
Described seepage brick is seepage brick, coal dust brick or the common building brick of municipal rainwater-collecting.
Described joint filling is processed can use cinder for building or quartz sand.
Described infiltration collection material comprises cinder, sand or gravel particle.
The invention has the beneficial effects as follows:
(1) provide a kind of continuous filter for the moisture solid waste of mummification, compared with natural evaporation only, using this continuous filter to process moisture solid waste can weatherproof, reaches stable dehydration concentrated effect.
(2), with thermal evaporation crystalline phase ratio, the method that mummification is oozed in filter can avoid consuming a large amount of energy.If adopt multiple-effect evaporation or mechanical recompression, evaporate water per ton and consume respectively approximately 0.35 ton of steam or power consumption approximately 40 degree.
(3) continuous filter of the present invention has material and is easy to get, and safeguards simply, and slagging-off is convenient, builds the features such as flexible.Be applicable to the mummification of different regions, different material.
(4) the percolate intractability that uses the present invention to collect is higher, can deliver to low side water user and use, as rush ash, prevent dust, water coal etc.Containing organic percolate, also can adopt the processing methods such as advanced oxidation, to obtain better reducing organic effect.
