Meanwhile, for the convenience of production scheduling, the total gate valve of the liquid that dams is set on the pipeline connecting with percolate influx of garbage filter liquid pool 1; On the vent pipe of clean water basin 10, shut off valve is set.
Meanwhile, for the convenience of safe operation and production scheduling and repair apparatus, the pipeline a101 connecting in described inclination
On liquid shut off valve a201 is set, on the pipeline b102 connecting in described inclination, be provided with liquid shut off valve b202, on the pipeline d104 connecting in described inclination, be provided with liquid shut off valve d204, on the pipeline f106 connecting in described inclination, be provided with liquid shut off valve f206, on the pipeline g107 that described inclination connects, be provided with liquid shut off valve g207, on the pipeline h108 connecting in described inclination, be provided with liquid outlet valve h208; On the pipeline c103 connecting in described inclination, be provided with mud shut off valve c203.On the pipeline e105 connecting in described inclination, be provided with mud shut off valve e205.On the pipeline s109 connecting in described inclination, be provided with liquid shut off valve s209, on the pipeline w111 connecting in described inclination, be provided with liquid shut off valve w211, on the pipeline m110 connecting in described inclination, be provided with mud shut off valve m210.
Its equipment: barrier 2, the bulk matter that can dam in percolate, as: branch, stone, plastics bag etc., prevent that it from entering subsequent disposal link.
Calcium hydroxide is thrown in causticization pond 3 in its pond, and it act as: destroy chain rupture 1..2. sterilization.3. make organonitrogen carry out ammonification.4. improve the pH value of water, 5. remove water-borne glue body material, 6. dephosphorization and removal suspended substance.Water after process in this pond can be removed COD
cr, BOD
5about 40%-50%, NH
3the about 40%-50% of-N.
Aeration tank 4, its Main Function is: 1. increased the dissolved oxygen of processing water, 2. separation the ferrous iron in aeration tank, manganese etc., make arsenic etc. that co-precipitation occurs simultaneously.Increased the dissolved oxygen in water, be convenient to aerobe bacterium and breed and absorb degradation of contaminant.Through processing, effectively reduced the BOD in percolate, COD and ammonia nitrogen, can also remove the metals such as iron, manganese, made water quality generation remarkable improvement simultaneously.Water after process in this pond can be removed COD
cr, BOD
5about 46%-54%, NH
3the about 70%-80% of-N, Te
2+about 55%-65%.
Settling tank 5 and 7, utilizes precipitating action, makes clear water separated with the flocs unit of the 4 interior formation in aeration tank.At its settling tank, throw in discoloring agent, charge neutrality and the organic macromolecule bridging action of performance inorganic flocculating agent, the pollutent that leading portion operation is not yet flocculated flocculates again, makes flocs unit large and closely knit, and shear resistant is good, accelerates settling velocity.In addition, in discoloring agent, contain efficient sterilizing composition, can effectively kill dewater middle bacterium and other microorganism.Its clear water liquid outlet that to be supernatant liquor arrange through the top of settling tank 5 and 7 is to filtering basin 8, and its throw out is that the liquid outlet that arranges through the bottom of settling tank 5 and 7 of mud is to sludge sump 6.
In its sludge sump 6, be provided with slush pump, partly precipitated thing, with the mud of biological bacteria, is back to the interior continuation cycle operation in aeration tank 4 by pipeline c103.
Filtering basin 8, be supernatant liquor after spoke stream precipitation is entered there is filtration, adsorbing multiple material, pollutent residual in water is carried out to Filtration Adsorption, water quality is further improved, reach national secondary discharge standard.
Reverse osmosis membrane processing pond 9, is conventional depth treatment process, because leading portion operation water quality treatment is better, then adopts reverse osmosis membrane processing technique to carry out advanced treatment, can make water quality further improve, and reaches or is better than national grade one discharge standard.
In technique scheme, liquid is an operation pond natural flow backward from last operation pond, with stream naturally, replaces machinery to promote stream, makes working cost reduce by 50% left and right than traditional technology.
