Accompanying drawing 2 is structure principle charts of bamboo charcoal cylindrical sludge modifying machine.
Among the figure 1 is agitator motor, the 2nd, and agitator motor, the 3rd is discharged with valve, the 4th, intake pump, the 5th, liquid-level controller, the 6th, filler filling bed, the 7th, filler lysate.
Embodiment
Contrast accompanying drawing 1, the sewage disposal flow process that has the round shape modifying machine to participate in: sewage is inserted first inlet of preliminary sedimentation tank by the delivery port in pre-treatment pond after the pre-treatment facility is handled, enter preliminary sedimentation tank, the big material of the particle that sinks in preliminary sedimentation tank; Supernatant liquor in the preliminary sedimentation tank inserts the inlet of aeration tank by the outlet of preliminary sedimentation tank, enter the aeration tank, sewage behind the aeration inserts the inlet of settling tank by the outlet of aeration tank, enter settling tank, post precipitation mud inserts the inlet of sludge thickener by first outlet of settling tank, enter sludge thickener, excess sludge stores in concentration basin; A part of sewage through the settling tank post precipitation exports the inlet that inserts sterilization pool by second of settling tank, enters sterilization in the sterilization pool, and the sewage after the sterilization outwards discharges; Insert the inlet of modifying machine through the supernatant water of a small part of settling tank post precipitation by the 3rd outlet of settling tank, enter the round shape modifying machine; Enter the interior supernatant water of round shape modifying machine with compressing into through air compressor machine, the nano level microbubble of sending into from round shape modifying machine cylinder center bottom rises slowly, form circulation from the packing area that flows in the round shape modifying machine all around downwards after arriving round shape modifying machine cylinder center top, the nano level microbubble breaks at filling surface, control the amount of being corroded of filler with the density of microbubble, impel filler to be dissolved in the sewage and uniform mixing, outlet by the round shape modifying machine second inlet that inserts preliminary sedimentation tank returns preliminary sedimentation tank then, the sewage that inserts preliminary sedimentation tank with the pre-treatment pond mixes, and repeats above-mentioned treating processes; Detect the sewage character (as COD, ammonia nitrogen, phosphorus concentration) that flows into water and have gap with the anticipation index; Unlatching motor, water pump, air pump make it work, and water pump is sent into the settling tank supernatant liquor from modifying machine top, and air pump is sent into microbubble by aeration head from the modifying machine bottom, and the backflow water yield and gas pushing quantity are by the detected result decision of effluent stream entry; Utilize microbubbles rupture strength impact filler in the bubble suspension, the filler that the chip that comes off after filler is corroded forms the concentration homogeneous suspends, solvent soln; Air pump, water pump quit work, and the filler lysate is discharged with automatic valve by discharging.Also can temporarily be stored in attached storage device (be filler dissolving liquid bath), store content is gone into the detected result of the water yield by discharging with automatic valve according to effluent stream, is controlled in the 1.3-1.5 times of scope of round shape modifying machine volume; Open attached storing device outlet valve, the filler lysate is injected in the preliminary sedimentation tank mixes.
The described sewage character that flows into water that detects, it detects used proofing unit or instrument adopts general water quality analysis instrument.
Contrast accompanying drawing 2, the bamboo charcoal cylindrical sludge modifying machine, its structure is that cylinder inner wall is the filler zone, agitator motor 1 inserts packing groove can make the relative cylinder in filler zone rotate, one termination aeration head of air delivery pump 2, aeration head is at modifying machine bottom centre place, and the water-in on round shape modifying machine top connects the output terminal of intake pump 4, and round shape modifying machine bottom joins by the input terminus of discharging with electrically operated valve and filler lysate storage pool; The control end of liquid-level controller inserts the liquid level in the round shape modifying machine.
Described liquid-level controller can adopt liquid-level controller product general on the market, as float-ball type liquid level meter or Float cylinder type liquid level meter, according to required filler lysate concentration control liquid level, under the certain situation of gas pushing quantity, liquid level is high more, microbubble concentration will be low more, and the filler lysate concentration of generation is also low more; Filler lysate concentration was high more when in like manner, liquid level reduced.Rising pipe is put in liquid-level controller top, to control high liquid level (HLL).
As UQK type float-type liquid level controller,, utilize the variation synchronously of ball float and liquid level and cause that magnetic switch moves and carry out work by isolated ball float group each other and two most of compositions of sets of contacts.When liquid level raise, the magnetic axle sleeve entered in the foreign field thereupon, and the magnet steel adhesive makes switch motion, and contacts status changes.Simultaneously, when liquid level descended, the magnetic axle sleeve descended, and magnet steel discharges, and the contact is converted to another state.
The round shape modifying machine is the biological culture groove, and its cylinder inner wall has box-like filler zone, adopts the alr mode of the diffusing gas in revolving drum center to mix liquid; By agitator motor the relative cylinder in filler zone is rotated, sewage and the filler that is corroded are mixed; Air delivery pump is supplied gas to modifying machine bottom centre place by aeration head; Modifying machine adopts the flow pattern of top water inlet bottom water outlet; Microbubble what and filler dissolution rate can be adjusted by the air operational throughput of control air delivery pump; After the effluent stream inlet was carried out water quality detection, addition and frequency to the filler lysate during according to its fruitage carried out inching, and the air flow quantity that the concentration of filler lysate is sent into by system's control air delivery pump realizes.
The addition of the filler solution that the COD of inflow sewage, ammonia nitrogen, phosphorus concentration and filler dissolving liquid bath produce has dependency, aeration rate in filler strength of solution that additional unit produces and the device is linear scaling, be rich in the solution of microbubble, its molten gas stable in properties.According to detected inflow sewage quality character, utilize motor, air pump control to be rich in the generation of microbubble liquid, and then by controlling the size of internal recycle liquid measure in the entire treatment system, accurately trace is controlled dissolution of fillers speed, to adjust inflow water water-quality constituents; Switch type ground discontinuous operation is carried out in modifying machine water inlet and water outlet respectively.
Organic and inorganic pollutant in the sewage treatment process can be degraded by part or all through absorption and the utilization of microorganism.In this process, sewage (former water) plays the effect of culturing micro-organisms, if the disappearance part material in the sewage, the microbial biochemical decomposition course just can't play one's part to the full, and the result is few
The bacterial classification of number kind and the mud that does not decompose fully (low digestibility mud) mix and produce the not active excess sludge of a large amount of corrupt types, and are attended by stench.
The present invention utilizes the compound nutritional microbial preparation insufficient part material in the unbalanced sewage (former water) that supplements the nutrients, promote mud to decompose the breeding of necessary multiple microorganism, make take place malodorous corrupt type not active sludge change over malodorous complete ripeness type active sludge do not take place.And, form a suitable effective microorganism survival environment inside in all quantity that reduces and suppress large-scale protozoa in the field of handling.
