Blodisc is a kind of biomembrance process sewage disposal technology, in fields such as sanitary sewage, trade effluents, application is arranged more.Because advantages such as cost are low, easy and simple to handle, the sludge creation amount is little, become one of optimum handling technology of small-scale sewage factory.In Europe, America, the blodisc technology has a large amount of and time-honored application in small-sized sanitary sewage is used.
But, domesticly do not carry out the innovation of blodisc technology for the raising of state sewage emission standard, the practical situation that are not also sewage for domestic rural area, samll cities and towns are simultaneously carried out respective application and are improved.The shortcoming of existing blodisc equipment is as follows:
(1) maintenance management is difficult, power consumption is large;
When (2) moving, sanitary condition is poor, smells foul;
(3) can not bear the fluctuation of water quality, the water yield, job insecurity;
(4) the debugging biofilm cycle long, cut easily and come off;
(5) do not possess dephosphorization and denitrogenate function.
The utility model content
The utility model provides a kind of modularization blodisc Sewage treatment systems convenient, simple to operate, that working cost is low of installing.
Realize the utility model purpose modularization blodisc Sewage treatment systems, comprise successively the pre-processing module pond that is connected, blodisc module pond and advanced treatment module pond;
Described pre-processing module pond is used for the pre-treatment of precipitation, water quality and quantity adjusting, sewage sludge storage, anaerobic digestion, denitrification and the chemical dephosphorization of waste water;
Described advanced treatment module pond is used for further removing suspended substance and other pollutents, and disinfection.
Described blodisc comprises rotation axis, disc, wastewater oxidation treatment trough and drive unit; Described disc is positioned at the wastewater oxidation treatment trough, described drive unit connection of rotating axle, and described rotation axis connects disc.
The beneficial effect of modularization blodisc Sewage treatment systems of the present utility model is as follows:
Modularization blodisc Sewage treatment systems of the present utility model, take new bio-disc equipment as core, modular front and back pretreatment unit, adopt the integral device modularized processing, flexible design, install convenient, simple to operate, system reliable, operation and working cost low, and do not need aeration and sludge reflux, save energy, just can obtain higher decontamination effect improving in shorter duration of contact, and do not need the professional technique maintenance personnel of Special Training, can effectively solve the processing difficult problem of domestic rural area, samll cities and towns etc. small-sized sanitary sewage.
Description of drawings
Fig. 1 is the structural representation of modularization blodisc Sewage treatment systems of the present utility model.
Embodiment
As shown in Figure 1, modularization blodisc Sewage treatment systems of the present utility model comprises successively the pre-processing module pond 1 that is connected, blodisc module pond 2 and advanced treatment module pond 3;
Described pre-processing module pond 1 is used for the pre-treatment of precipitation, water quality and quantity adjusting, sewage sludge storage, anaerobic digestion, denitrification and the chemical dephosphorization of waste water; Greatly reduced floor space, simplified flow process, be convenient to automatic operating, management is simple.
Described advanced treatment module pond 3 is used for further removing suspended substance and other pollutents, and disinfection.
Described blodisc module 2 comprises rotation axis 7, disc 5, wastewater oxidation treatment trough 4 and drive unit 6; Described disc 5 is positioned at wastewater oxidation treatment trough 4, described drive unit 6 connection of rotating axles 7, and described rotation axis 7 connects disc 5.Effluent stream is through wastewater oxidation treatment trough 4, drive unit 6 drives disc 5 rotations and makes the microbial film on disc 5 alternately contact with air with sewage, form a continuous oxygen uptake, absorption, oxidation decomposition course, the organism in the interior sewage of wastewater oxidation treatment trough 4 is reduced, sewage is purified.The organic contamination beyond the region of objective existence is removed in the blodisc decapacitation effectively, and along with thickening of film, the microorganism of internal layer is anaerobic state, also has the function of nitrated, denitrification and dephosphorization.
The principle of work of modularization blodisc Sewage treatment systems of the present utility model is as follows:
Modularization blodisc equipment is comprised of disc, tank, main shaft and drive unit.
After biofilm was completed, disc surface formed microbial film, and during the equipment operation, disc slowly rotates under main shaft drives, and along the dish Clearance Flow, the organism in sewage is by the absorption of the microbial film on coiling, and then degraded in tank for sewage.
Aerobe rotating disk submergence rate is generally in 40% left and right, in service, when the part disc leaves the water surface, panel surface forms one deck sewage film, airborne oxygen is dissolved in moisture film and utilizes for microorganism, the oxidized decomposition and inversion of organism in sewage is small-molecule substance and energy, and propagation forms new cellular material.These effects are as follows:
[organism]+O
2-→ CO
2+ H
2O+[energy]
[organism]+O
2+ NH
3→ [propagation of microorganism]+CO
2+ H
2O+[energy]
In addition, in microbial growth, wherein part is also carried out metabolic reaction in the following way:
[microorganism]+O
2→ CO
2+ H
2O+NH
3+ [energy]
Disc often circles, and namely carries out replacing of primary sorption one oxygen uptake process.Like this, the microbial film on disc alternately contacts with sewage and atmosphere, and iterative cycles is degraded the pollutent in water under microbial process, and the microbial film on the while disc is constantly grown, aging and self falling.
Anoxic blodisc submergence rate is generally in 100% left and right, and disc moves under anoxia condition, in the situation that backflow nitrification liquid and carbon source exist, following reaction occurs in the microbial film of disc surface:
[organism]+NO
3-→ [microorganism propagation]+CO
2+ H
2O+[energy]
[organism]+NO
3-→ H
2O+CO
2+ N
2+ OH-+[energy]
Through above-mentioned reaction, realize the function of denitrogenation.
In addition, in microbial growth, wherein oxygenolysis also occurs in part in the following way:
[microorganism]+O
2→ CO
2+ H
2O+NH
3+ [energy]
Dish often circles, and namely carries out replacing of primary sorption one oxygen uptake process.Like this, the microbial film on disc alternately contacts with sewage and atmosphere, and iterative cycles is degraded the pollutent in water under microorganism (being microbial film) effect, and the microbial film on the while disc is constantly grown, aging and self falling.
The advantage of modularization blodisc Sewage treatment systems of the present utility model is as follows:
(1) cost of disposing of sewage is lower, and the running energy consumption is about the 1/3-1/4 of activated sludge process.
(2) the contact reacts time is short.Recommend the residence time to be about 0.25-2h, save large quantity space.
(3) biophase classification, surging flora effect is obvious, has the function of nitrification and denitrification.
(4) sludge quantity that produces is few, is roughly 1/2 left and right of activated sludge process.
(5) can process from the sewage of 40000mg/L～10mg/L scope, and can obtain treatment effect preferably.
(6) has phosphorus removal functional.
(7) be easy to maintenance management, daily time-based maintenance gets final product to equipment.
(8) noise is low, and the filter tank fly that yet do not grow does not produce stench and foam.
Embodiment recited above is described preferred implementation of the present utility model; be not that scope of the present utility model is limited; do not breaking away under the spiritual prerequisite of the utility model design; various distortion and improvement that the common engineering technical personnel in this area make technical solutions of the utility model all should fall in the definite protection domain of claims of the present utility model.
