Description
Technical field
The present invention relates to the technical field of sanitary sewage disposal, particularly a kind of new and effective biological rotating disk.
Background technology
Sanitary sewage is mainly resident's daily life water, containing substantial amounts of organic pollution in sewage, if this organic pollution will affect groundwater quality without process.At present, before sewage effluent, all needing to remove the organic pollution in sewage, the process technique adopted has following: (1) A/O technique, and A/O technique is using activated sludge as bio-carrier, makes sewage reach the purpose of oxygenation by the effect of blower fan oxygen supply aeration.A sets mechanical agitation in pond, is back to A pond from O pond, carries out anti-nitration reaction in A pond, major part nitrate nitrogen is reduced into nitrogen, and makes nitrogen overflow from waste water by stirring, reaches to remove the purpose of ammonia nitrogen；A pond discharges water to O pond, sets blast aeration in O pond, removes majority of organic pollutants, and the most ammonia-nitrogen in water inlet is changed into nitrate nitrogen；According to the needs of waste water, the activated sludge concentration in O section pond can be adjusted, by the zoogloea in activated sludge, the Organic substance in absorption, oxidation Decomposition Wastewater；Organic substance, ammonia nitrogen removal frank are high.Owing to not having independent sludge recirculation system, thus the mud with unique function can not be turned out, the degradation rate of hard-degraded substance is relatively low；To improve nitric efficiency, it is necessary to strengthening nitrate recirculation ratio, thus increase operating cost, it addition, internal recycle liquid is from Aeration tank, containing certain DO, make A section be difficult to keep desirable anaerobic condition, affect denitrification effect, denitrification percent is extremely difficult to 90%.Sum it up, this technique civil engineering and operating cost are relatively big, take up an area more, and follow-up maintenance, complex management.(2) SBR method, SBR method and sequencing batch active sludge, be a kind of relatively advanced activated sludge process that developed recently gets up, and this process technique integrates Aeration tank, sedimentation tank, continuum micromeehanics, intermittent aerating, settlement of sewage when stopping the supple of gas or steam, exclude supernatant, become a cycle, go round and begin again.SBR method does not set sedimentation tank, and without sludge reflux equipment, but SBR method is intermittent duty, need to set multiple processing unit, and water inlet and aeration switch mutually, causes control complex.Automated condtrol is required significantly high by SBR technique and it needs to substantial amounts of electric control valve and machinery water decanter, slightly fault can not be run.In order to ensure weir loading, water decanter device fabrication is required height by SBR method, must keep on improving, otherwise very easily cause final outflow water water quality not up to standard during making.The domestic quality that there is presently no strains wetting system preferably, import equipment buying trouble, and expensive, and maintenance cost is also high from now on simultaneously.In SBR method pond, sludge concentration is measured by concentration meter to control to discharge unnecessary sludge quantity, and current domestic concentration meter quality is still not really up to the mark, causes mud discharging to control more difficult.Owing to there is several functions in a pond, relevant device must not leave unused then, and the quantity of aeration head and the ability of aerator must be slightly larger, thus add cost of investment and operating cost.Running additionally, SBR belongs to change water level, power consumption increases, and too increases operating cost, and its denitrogenation dephosphorizing efficiency is less high, and sludge stabilization neither be fine, and therefore SBR is not the process choice that this engineering is best.

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention will be further described, and protection scope of the present invention is not limited to the following stated:
As depicted in figs. 1 and 2, a kind of new and effective biological rotating disk, it includes reactive tank 1, power transmission shaft 2, gripper shoe 3, disc 4, two-port valve 6 and water pump 7, on the top surface of described reactive tank 1 and be positioned at the both sides of reactive tank 1 and be provided with bearing block 5, between two bearing blocks 5, power transmission shaft 2 is installed, power transmission shaft 2 is provided with two gripper shoes 3, multiple disc 4 it is provided with on power transmission shaft 2 and between two gripper shoes 3, the latter half of each disc 4 may be contained within reactive tank 1, the top of described reactive tank 1 and be positioned at the both sides of reactive tank 1 and be provided with support 11, it is provided with air inlet pipe 12 between two supports 11, the lower surface of air inlet pipe 12 and the length direction along air inlet pipe 12 are provided with multiple shower nozzle 10, shower nozzle 10 is arranged at the surface of disc 4, the sidewall of described reactive tank 1 is additionally provided with the through hole A8 and through hole B9 of connection reactive tank 1, through hole A8 is arranged at the left side of reactive tank 1, through hole B9 is arranged at the right side of reactive tank 1., the arrival end of water pump 7 is connected with through hole A8, and the port of export of water pump 7 is connected with the water inlet of two-port valve 6, and the port of export I of two-port valve 6 is connected to blow-off pipe 13, and the port of export II of two-port valve 6 is connected with through hole B9.
The described spacing between often adjacent two discs 4 is equal；Power transmission shaft 2 is hollow axle.
The work process of the present invention is as follows: first entered by sewage in reactive tank 1, what disc 4 part replaced contacts with air and sanitary sewage, disc 4 can be formed attachment one layer after a period of time and perch the biomembrane of a large amount of microorganism, power transmission shaft 2 is made to rotate, power transmission shaft 2 drives disc 4 to rotate, sewage is along disc 4 Clearance Flow in reactive tank 1, and the organic pollutant in sewage is adsorbed by the biomembrane on disc 4；When disc 4 leaves the water surface, disc 4 surface forms one layer of sewage thin film, oxygen in air is constantly dissolved in moisture film, in biomembrane, microorganism absorbs dissolved oxygen, the organic pollution that oxidation Decomposition is adsorbed, and disc 4 often transfers one week to, namely the journey of primary sorption oxygen uptake oxidation Decomposition is carried out, along with the continuous rotation of disc 4, pollutant are oxidized decomposition constantly, it is achieved thereby that the filtering of dirty water pollutant.And the biomembrane that produces in reacting is also aging gradually and be deposited on disc 4, now only need to passing into the air with pressure in air inlet pipe 12, air sprays through shower nozzle 10, thus being blown down by aging biomembrane, avoid bulk deposition, it is ensured that being successfully generated of neoplasm film.After process after a while, detecting water quality situation, if water quality reaching standard, start water pump 7 and make the port of export I of two-port valve 6 turn on, water up to standard is discharged by water pump 7 in reactive tank 1；If water quality is not up to standard, starting water pump 7 and make the port of export II of two-port valve 6 turn on, sewage via through holes B9 pours in reactive tank 1, rolls so that being deposited on the pollutant bottom reactive tank 1, it is simple to absorbed by biomembrane, to improve the treatment effeciency of pollutant.
