Equipment of the present invention also is provided with PLC Controlling System, warning device.
The method of the garbage leachate of processing municipal solid waste incinerator of the present invention comprises:
(1) pre-treatment: the ss suspended solid that garbage burning factory oozes in the drop liquid is very high, and generally greater than 8000mg/L, so pre-treatment mainly is to remove suspended substance, and present method adopts centrifuge dehydration to carry out solid-liquid separation, and clearance is between 85～90%.Because garbage burning factory is to the environment requirement height, produce for avoiding stink, adopt closed, easy to operate centrifuge.Mud after the centrifuge dehydration is transported to the refuse chute burning disposal of garbage burning factory with sludge pump, and the drop liquid that oozes after the separation enters intermediate pool by pump, with the continuous water inlet that guarantees system and the normal operation continuously of membrane bio-reaction system.
(2) membrane biological reaction is handled: adopt membrane bio-reaction system to handle, with ooze the biochemical reactor that drop liquid be transported to membrane bio-reaction system of pump with intermediate pool, adopt the aeration of diving stirring efficiently to carry out aerobic treatment, biochemical sludge can constantly be tamed into highly active aerobic microbiological flora by the aeration cultivation or the mud of municipal sewage plant, oozing drop liquid purifies waste water and mud by ultra-filtration and separation after biochemical treatment, high concentration sludge after the separation is got back in the biochemical reactor, make sludge concentration reach 10-30g/L, can the degrade organism of about bio-degradable of about 90%, and also can progressively degrade to the organism of difficult for biological degradation, and making part ammonia nitrogen and organonitrogen by biosynthesizing and oxidation removal, the pollutent that residue is not removed is finally held back by disc tube reverse osmosis (dt-ro) DTRO system.
The water outlet of biochemical system enters ultrafiltration (UF) system, compare with traditional biochemical processing process, microbial cells separates by the high-performance ultrafiltration system, guarantee that particulate matter, microorganism and the suspended substance relevant with chemical oxygen demand COD greater than 0.02 μ m are trapped in the system safely, the ultrafiltration peak pressure is 6bar.The ultrafiltration clear liquid enters water tank, guarantees the storage of rinse water when the continous-stable operation of follow-up disc tube reverse osmosis (dt-ro) system and system are cleaned.
After membrane bio-reaction system (MBR) processing, biochemical oxygen demand (BOD) COD can remove 90%, ss suspended solid can reach 100% clearance, ammonia nitrogen and can remove about 50%, but its effluent index differs greatly with the relevant emission standard of regulation, and the therefore follow-up employing membrane process craft that needs is handled to reach national specified discharge standard.
Biochemical system is when summer operation, under the high situation of water temperature background values, the heat energy that energy that biological degradation discharges and high efficient aeration produce makes water temperature can be higher than 37 degrees centigrade, but this activity to biological bacterium in the biochemical system is disadvantageous, therefore need lower the temperature by cooling system.Cooling system comprises cooling tower, heat exchanger and recycle pump, oozes drop liquid through over-heat-exchanger and cold water source (getting final product with tap water) heat exchange cooling, and cold water source,, returns heat exchanger and recycles after the cooling tower cooling to cooling tower with pump delivery.
(3) reverse-osmosis treated: adopt disc tube reverse osmosis (dt-ro) treatment system (DTRO) to hold back most pollution substances, make the moisture that oozes in the drop liquid see through reverse osmosis membrane by pressure in the percolate input dish tubular type reverse osmosis drop device after membrane bio-reaction system is handled with pump, most pollution substances are held back.Adopt the disc tube reverse osmosis (dt-ro) treatment system.
Reverse osmosis is the phenomenon opposite with the naturally osmotic process, promptly under the ambient pressure effect, the process that solvent is separated out by semi-permeable membranes, the DTRO system utilizes the principle of reverse osmosis technology, make the water molecules in the penetrating fluid see through reverse osmosis membrane by pressure, all contaminants matter is comprised the small molecules solute, hold back greater than molecule and the ion of 1nm, purify the purpose of oozing drop liquid thereby reach as ammonia nitrogen etc.Disc tube reverse osmosis (dt-ro) DTRO system is main by removing micromolecular organism, ammonia nitrogen and adjusting the pH value in this technology, the water outlet that guarantees the entire treatment system reaches related standards, and the highest can reaching " urban sewage reutilization city miscellaneous water water quality standard " (GB/T18920-2002).Because DT-RO film group has special hydromeehanics design, make it to be suitable for handling high opacity and the high waste water that contains the sand coefficient, the waste water SDI value that enters the film group can reach 20, also can reach 40 and contain the sand coefficient.The installation, maintenance of DT-RO treatment system is simple, and is easy to operate, the level of automation height.
Disc tube reverse osmosis (dt-ro) DTRO system adopts first-stage reverse osmosis, and the rate of recovery is about 80%, and system comprises core formula filtration fraction, film post part, dosing part and wash section.With sulfuric acid the pH value is transferred to less than 6.5, is entered core formula strainer then, its precision is nominal 10 μ m, and filter core needs more renew cartridge when pressure reduction reaches 0.2～0.25MPa.The drop liquid that oozes through core formula strainer pumps into one-level disc tube reverse osmosis (dt-ro) film column system by ram pump, water outlet after reverse-osmosis treated can reach " domestic refuse sanitary filling field pollute control criterion " first grade discharging limit value in (GB16889-1997), and concentrated solution is with the refuse chute burning disposal of pump delivery in the incineration plant.
Because the inflow temperature of disc tube reverse osmosis (dt-ro) DTRO system can not be above 30 degrees centigrade, and after membrane bio-reaction system MBR handles, ooze the drop liquid temp about 37 degrees centigrade, therefore need carry out thermal exchange by heat exchanger and cold water source, make temperature reduce to below 30 degrees centigrade, cold water source is with the cooling tower of pump delivery in membrane bio-reaction system MBR treatment system cooling process together.
After operation for some time, need clean ultra-filtration membrane group and disc tube reverse osmosis (dt-ro) film group, cleaning system comprises volume pump, medicine storing pot etc.Cleaning process has system to clean and two kinds of matting:
System flushing: the flushing of film group must be carried out when each system closing.The auto stop during system fault is also carried out cleaning procedure.The main purpose of flushing is to prevent that the pollutent that oozes in the drop liquid from depositing at membrane surface.Flushing is divided into two kinds, and a kind of is to wash with oozing drop liquid, and a kind of is water purification, the clear liquid flushing after the available system handles of the present invention, and the time of two kinds of flushings is generally all at 2～5 minutes.
For keeping the diaphragm-operated performance, the film group should regularly be carried out matting.Clean-out system divides acidic cleaner A and two kinds of alkaline cleaner C (Beijing Tiandiren Environment-Tech Co., Ltd produces and sells), and the main effect of alkaline cleaner is to remove organic pollution, and the main effect of acidic cleaner is to remove inorganic pollution.Usually carry out alkalescence earlier and clean, carry out acidity again and clean, when cleaning, detergent solution is at film group system internal recycle, and to remove the pollution substance that is deposited on the diaphragm, scavenging period was generally 1～2 hour, but can stop at any time.Liquid discharge system after cleaning finishes is to preaeration tank.Clean-out system generally is diluted to 5～10% backs and uses.The matting cycle: scavenging period length at interval depends on the pollutant concentration in the water into, recommends following parameter:
The alkalescence cleaning interval is: 100～200 hours.
The acid cleaning interval is: 200～400 hours.
