Fig. 2 is the structural representation of the sludge deep processing system of odorless of the present invention.
Detailed description of the invention
With detailed description of the invention, the present invention is described in further detail below in conjunction with the accompanying drawings.
As it is shown in figure 1, be the sludge deep processing method of a kind of odorless of the present invention, comprise the following steps:
A) add heavy metal chelating agent to the mud collecting pit of sewage treatment plant and carry out electro-osmosis, removing the heavy metal in mud;
B) use mud charging hopper that the mud of step a) gained carries out subpackage to throw on filter cloth, spray Lumbricus enzyme bacterium solution to mud, package mud and obtain mud bag;
C) mud bag is carried out mechanical presses dehydration, be reduced to 30-50% through the multistage continuously extruded moisture content making mud;
D) add pulverized agricultural wastes mix homogeneously to the mud of step c) gained, and add building curing agent and be pressed into the mud pan for planting nursery stock or flowers.
Specifically, step a) adds heavy metal chelating agent at the mud collecting pit of sewage treatment plant and carries out electro-osmosis, the heavy metal ion in sewage is made to be caught by heavy metal chelating agent and mutually chelate with it, under the electrodynamic action of negative electrode and anode, heavy metal chelate sinks down into the bottom of mud collecting pit.Wherein, the heavy metal chelating agent a kind of or the most two or more mixing in nickel trapping agent, cadmium trapping agent, chromium trapping agent, manganese trapping agent, hydrargyrum trapping agent, copper trapping agent, zinc trapping agent.When heavy metal chelating agent and heavy metal ion after completion of the reaction, extract the mud of mud collecting pit out and carry out the content of beary metal in filter pressing detection is extracted out simultaneously mud, stop when the mud aspect that content of beary metal exceeds standard being detected extracting filter pressing out.
The mud exceeded standard for content of beary metal remaining in mud collecting pit, carries out filter pressing decrement, solar energy desiccation decrement successively after extraction, the moisture content making the mud that content of beary metal exceeds standard is 10%-15%.On the one hand, according to content of beary metal, the mud that the content of beary metal through minimizing exceeds standard can be delivered to have the useless processed in units processing qualification of danger according to the instruction of Environmental Protection Agency, or carries out burning disposal;On the other hand, may also take on firming agent and isolate combination technology with film, that is: the mud exceeded standard through the content of beary metal of minimizing is added after building curing agent is solidified into bulk, use film parcel solidification sludge block, then use concrete grouting that solidification sludge block is wrapped up molding.So, by solidification sludge block is wrapped in concrete product, both can stop the harm to environment of mud that content of beary metal exceeds standard, it can be made again to be utilized.
For the mud that content of beary metal is up to standard, step b) uses mud charging hopper it is carried out subpackage and throws on filter cloth, on the one hand use filter cloth parcel mud to process, enough oxygen can be provided for follow-up enzyme catalysis, on the one hand be easy to follow-up mechanical presses dehydration.Then the sprinkling of the mud on filter cloth Lumbricus enzyme bacterium solution carries out enzyme catalysis to mud, packages mud and obtains mud bag.Containing multiple protein hydrolytic enzyme in Lumbricus enzyme bacterium solution, the molecule generation enzymic catalytic reaction of stink can be produced in mud under conditions of high pressure, make it be decomposed into carbon dioxide and water at normal temperatures, mud is had good deodorizing effect.Preferably, the fountain height of Lumbricus enzyme bacterium solution is that every 150kg mud sprays 10~20g Lumbricus enzyme bacterium solution.
Step c) applies different pressure to mud and is dehydrated, and specifically, the water content in high pressure and low pressure alternately extruding on the one hand mud reduces rapidly, on the other hand the biomembrane of microorganism can be made to rupture.Additionally, mud containing Lumbricus enzyme bacterium solution under high pressure can produce the enzyme catalysis transfer reaction of 1-1000 each second hundred million times, the long-chain molecule in mud can be made to degrade rapidly to short chain molecule, and regenerate carbon dioxide and water with the material of generation foul smell molecule in mud.Specifically, 6-8 mud bag one stacking bag of composition of every stacking, every 8-10 stacking is coated to hang in and carries out extrusion dehydration in mechanical presses device, until the moisture content of mud is reduced to 30-50%.Preferably, high pressure is 250~350 tons, extruding 3~12s every time, and low pressure is 50~150 tons, extruding 15~30s every time, and total extrusion time is 120~240min.The BOD of supernatant produced by extrusion dehydration5/ COD value is the highest, does not meets the standard of sewage treatment plant, therefore to improve the bio-degradable of the produced sewage of dehydration, adds Lumbricus enzyme bacterium solution and carry out enzyme catalysis in supernatant, until BOD5The sewage collecting pool of sewage treatment plant is entered after/COD value is up to standard.
In order to make recycling sludge utilize, step d) adds pulverized agricultural wastes mix homogeneously to mud, and add building curing agent and make the environmental protection mud pan for planting nursery stock or flowers, these mud pans can be degraded in 1-5, the most not only by sewage sludge harmlessness, minimizing, also make mud achieve and effectively recycle.Preferably, a kind of or the most two or more mixing during agricultural wastes are straw, mushroom residue, grass meal, tealeaf residue, Banana tree bar, Chinese medicine slag.
As in figure 2 it is shown, present invention also offers the sludge deep processing system of a kind of odorless, it includes that the sludge heavy-metal being sequentially communicated removes unit, mud enzyme catalysis unit, high pressure dewatering unit, curing molding unit;
Sludge heavy-metal removes unit and includes mud collecting pit and the heavy metal delivery device being arranged in mud collecting pit and electro-osmosis device;
Mud enzyme catalysis unit includes mud packaging device, Lumbricus enzyme bacterium solution flusher and moving track device;The entrance of mud packaging device connects with moving track device with the outlet of mud collecting pit, the outlet of mud packaging device, and Lumbricus enzyme bacterium solution flusher is arranged on described moving track device;
High pressure dewatering unit includes that the mud device of the mechanical presses device for being dehydrated mud and the mud in drawing off mechanical presses device, the entrance of mechanical presses device are connected with curing molding unit by mud device with the outlet of moving track device, the outlet of mechanical presses device;
Curing molding unit includes mixed processing pond and shaped device, the entrance in mixed processing pond and the outlet of dumping device, and outlet connects with shaped device.
Above-mentioned processing system also includes that sludge with heavy metals exceeding standard processing unit and supernatant process pond, sludge with heavy metals exceeding standard processing unit includes that sludge with heavy metals exceeding standard processes pond and filter-pressing device, the entrance in this process pond and the outlet of mud collecting pit, the outlet in this process pond connects with the entrance of filter-pressing device.Supernatant is processed the entrance in pond and is connected with the catch tray being located at mechanical presses bottom of device by pipeline.
