Description

A kind of new and effective biological rotating disk

Technical field

The utility model relates to the technical field of sanitary sewage disposal, 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, being required to remove the organic pollution in sewage, the process technique used 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；The activated sludge concentration in O section pond can be adjusted, the organic matter by the zoogloea in activated sludge, adsorbing, aoxidize in also Decomposition Wastewater according to the needs of waste water；Organic matter, ammonia nitrogen removal frank are high.Owing to not having independent sludge recirculation system, thus can not turn out the mud with unique function, 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, interior circulation fluid is from aeration tank, containing certain DO, make A section be difficult to keep preferable 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 i.e. sequencing batch active sludge, is a kind of relatively advanced activated sludge process that developed recently gets up, and this process technique integrates aeration tank, sedimentation basin, 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 basin, and without sludge reflux equipment, but SBR method is intermittent duty, need to set multiple processing unit, and water inlet and aeration mutually switch, and causes control complex.Automated condtrol is required the highest by SBR technique and it needs to substantial amounts of electric control valve and machinery water decanter, slightly fault can not run.In order to ensure weir loading, SBR method requires height to water decanter device fabrication, must keep on improving, the most easily cause final outflow water water quality the most up to standard during making.The domestic quality that there is presently no preferably strains wetting system, and import equipment buying bothers, and expensive, and maintenance cost is the highest the most from now on.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 the most 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 air blast 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 the highest, and sludge stabilization is not fine, and therefore SBR is not the process choice that this engineering is optimal.

Detailed description of the invention

Being further described the utility model below in conjunction with the accompanying drawings, protection domain of the present utility model is not limited to the following stated:

nullAs 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，Two gripper shoes 3 are installed on power transmission shaft 2，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 through hole A8 and through hole B9 of connection reactive tank 1 it is additionally provided with on the sidewall of described 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 connects 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 the most adjacent two discs 4 is equal；Power transmission shaft 2 is hollow shaft.

The course of work of the present utility model is as follows: first entered by sewage in reactive tank 1, what disc 4 part replaced contacts with air and sanitary sewage, after a period of time, attachment one layer on disc 4, can be formed 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 flows along disc 4 gap 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 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, the most once adsorb the journey of oxygen uptake oxidation Decomposition, along with the continuous rotation of disc 4, the most oxidized decomposition of pollutant, it is achieved thereby that the filtering of dirty water pollutant.And in reacting, the biomembrane of generation is the most aging and is deposited on disc 4, now only need to be passed through the air of band pressure in air inlet pipe 12, air sprays through shower nozzle 10, thus is blown down by aging biomembrane, avoid bulk deposition, it is ensured that being successfully generated of neoformation 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 in reactive tank 1 by water pump 7；If water quality is the most 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.
