Description
Technical field
The present invention relates to technical field of sewage, particularly a kind of sewage disposal device and method.
Background technology
In sewage disposal, the main pollutent of removing is an organism, also wants denitrogenation dephosphorizing, currently used treatment process that traditional activated sludge process, sequencing batch active sludge, anaerobic-anoxic-aerobic process and oxidation ditch method etc. are arranged sometimes.Traditional activated sludge process mainly is made up of aeration tank, settling tank, aerating system, mud return-flow system and excess sludge discharge system, its principle of work is that sewage enters and enters settling tank after the biodegrade of aeration tank again and carry out water outlet after the mud-water separation, sludge part is back to the aeration tank and keeps its stable sludge concentration in the settling tank, and excess sludge is discharged through the mud discharging system.This method has preferably organism in the sewage to be removed, but material removal effects such as the nitrogen in the sewage, phosphorus are relatively poor, so generally be applied to nitrogen, phosphorus are removed in the sewage disposal of no requirement (NR).Sequencing batch active sludge is to finish into water, aeration, precipitation, draining, idle five processes in same pond successively, form one-period, reach the purpose of removing organic pollutant by cycling service, also have the denitrogenation dephosphorizing effect simultaneously, required major equipment has aerating system, strains hydrophone, agitator etc.This method is because all processes are all carried out in same pond, so the intermittent time is long, it is few that the unit time is handled the water yield.In order to guarantee in when precipitation discharging requirements in water quality, need to adopt special water exhaust system-strain hydrophone, increased investment, increased the difficulty of Operation Administration and Maintenance simultaneously.Anaerobic-anoxic-aerobic process and oxidation ditch method can both produce anaerobism, anoxic, aerobic condition when operation, so can remove organism and denitrogenation dephosphorizing, but need special mud return-flow system, in anaerobic-anoxic-aerobic process, also need the sewage backflow system, so equipment used is more, floor space is big, and investment cost height, operational administrative inconvenience are used uneconomical in the middle and small scale sewage disposal.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the invention provides a kind of sewage disposal device and method, have that simple, the required auxiliary facility of flow process is few, operational management is convenient, treatment effect characteristics preferably.
In order to achieve the above object, the technical solution used in the present invention is:
A kind of sewage disposal device, comprise two identical aerated precipitation tanks, be aerated precipitation tank C and aerated precipitation tank D, the C4 gangway of aerated precipitation tank C links to each other by thrust-augmenting nozzle E with the D4 gangway of aerated precipitation tank D, the sewage inlet C1 of aerated precipitation tank C links to each other with sump pump A by inlet valve 1, the sewage inlet D1 of aerated precipitation tank D links to each other with sump pump A by inlet valve 2, the clear water water outlet C2 of aerated precipitation tank C links to each other with effluent outfall G by flowing water Valve 7, the clear water water outlet D2 of aerated precipitation tank D links to each other with effluent outfall G by flowing water Valve 8, the inlet mouth C5 of aerated precipitation tank C links to each other by the air outlet of air-supplying valve 3 and aerator B, the inlet mouth D5 of aerated precipitation tank D links to each other by the air outlet of air-supplying valve 4 and aerator B, the C3 sewage draining exit of the bottom of aerated precipitation tank C links to each other with spoil disposal valve 5, and the D3 sewage draining exit of the bottom of aerated precipitation tank D links to each other with spoil disposal valve 6.
Sewage enters aerated precipitation tank C and aerated precipitation tank D by valve 1 and valve 2 respectively, handles back sewage and discharges by valve 7 and valve 8 respectively; The demand of oxygen is supplied with by aerator B by valve 3 and valve 4 among aerated precipitation tank C and the aerated precipitation tank D, and its excess sludge is by valve 5 and valve 6 dischargings.
Principle of work of the present invention is:
When sewage enters aerated precipitation tank C, at first be anoxic mixing process, sewage is in anoxic, anaerobic state successively, and denitrifying bacterium carries out that anaerobically fermenting is carried out in denitrogenation, anaerobically fermenting bacterium, the polyP bacteria anaerobism is put phosphorus; Then carry out aeration, the aerobic microbiological decomposing organic matter, simultaneously nitrobacteria carry out nitrated, the excessive suction phosphorus of polyP bacteria, by the discharging dephosphorization of excess sludge, muddy water mixed solution enters aerated precipitation tank D and carries out mud-water separation, the supernatant liquor discharging.When sewage enters aerated precipitation tank D, carry out sewage when separating draining by aerated precipitation tank C, aerated precipitation tank D exists alternative anoxic, anaerobism, good oxygen condition too, can remove organism equally and have the denitrogenation dephosphorizing effect.
Method of the present invention is by periodically repeating operation, and the process in each cycle is as follows:
The first step, water intaking valve 1, outlet valve 8 are opened, and sump pump A opens thereupon, and sewage enters aerated precipitation tank C, at this moment, and aerated precipitation tank C sludge concentration height, mud just exists anoxic, anaerobic state successively; 0.5-1.0 steam supply valve 3 is opened after hour, aerator B opens, aerated precipitation tank C is carrying out oxygenic aeration and biological degradation, and mud mixture enters aerated precipitation tank D by thrust-augmenting nozzle E and carries out precipitate and separate, handle back sewage and discharge through outlet valve 8,
In second step, aerated precipitation tank C water inlet is after 5.0-6.0 hour, and sump pump A, water intaking valve 1, outlet valve 8 are closed simultaneously, stop into water, 0.5-1.0 after hour, aerator B, steam supply valve 3 are closed simultaneously, device is in idle quiet heavy state, 0.5 after hour, idle quiet heavy end
The 3rd step, water intaking valve 2, outlet valve 7 are opened, sump pump A opens thereupon, and sewage enters aerated precipitation tank D, at this moment, aerated precipitation tank D sludge concentration height, mud just enters anoxic, anaerobic state successively, and steam supply valve 4 is opened after 0.5-1.0 hour, aerator B opens and to carry out oxygenic aeration and biological degradation, and mud mixture enters aerated precipitation tank C by thrust-augmenting nozzle E and carries out precipitate and separate, handle back sewage by outlet valve 7 dischargings
In the 4th step, aerated precipitation tank D water inlet is after 5.0-6.0 hour, and sump pump A, water intaking valve 2, outlet valve 7 are closed simultaneously, stop into water, 0.5-1.0 after hour, aerator B, steam supply valve 4 are closed simultaneously, device is in idle quiet heavy state, 0.5 after hour, idle quiet heavy end
Next, sewage enters aerated precipitation tank C again, begins a new cycle of operation, and operational scheme is the same.
Aeration adopts blast aeration or jet-flow aeration mode, air quantity during according to aeration the size of sludge concentration regulate automatically by the computer automatic control system, the scope of sludge concentration is 2000-5000mg/l in the aerated precipitation tank, the aeration air quantity is 3.0-5.5m
3(air)/m
3(sewage) h.
Spoil disposal is carried out in the discharging of excess sludge when aerated precipitation tank is in the precipitate and separate state.
The whole service process is carried out full automatic control by the computer automatic control system.
Because by the aeration of alternately intaking, precipitate and separate operation, can realize automatically that sewage and mud reflux, need not special refluxing unit, have degradation of organic substances and denitrogenation dephosphorizing effect preferably, after the whole service process is provided with by the computer automatic control system, the control of implementation full-automatic regulation, few, the convenient operation and management of required equipment, the investment freight charges are low.
