Brief description of the drawings
Fig. 1 is control flow chart of the present utility model.
Detailed description of the invention
In order to make technical problem to be solved in the utility model, technical scheme and beneficial effect clearer, below in conjunction with drawings and Examples, the utility model is further elaborated. Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Gas gathering station sanitary sewage parameter
Former life sewage quality
According to the water quality characteristics of sanitary sewage, coal bed gas gas gathering station influent quality sees the following form:
| Sequence number | Index name | Unit | Raw water quality |
| 1 | CODcr | mg/L | 150～220 |
| 2 | BOD5 | mg/L | 50～100 |
| 3 | SS | mg/L | 100～250 |
| 4 | NH3-N | mg/L | 20～30 |
| 5 | TP | mg/L | 1.5～2.6 |
| 6 | PH value | 6～9 |
Effluent quality and discharge standard:
Sanitary sewage is not outer row after treatment, is back to water sprinkling path and greening water. In conjunction with relevant specification of country and standard, the discharge standard of this Waste Water Treatment is with reference to " People's Republic of China's miscellaneous domestic water quality standard " (CJ25.1-89) middle urban afforestation carwash, cleaning water standard.
Design water quality after treatment and standard as follows:
Process the water yield
According to the general staff's of gas gathering station quantity, it is as follows that gas gathering station processes water yield value:
Day is processed the water yield: 1m3/d, 3m3/d, 5m3/d.
Day processing time: 20h/d.
MBR film biological treating equipment is introduced:
Membrane biological reactor process has been strengthened the function of bioreactor greatly by the isolation technics of film, activated sludge concentration is improved greatly, and its hydraulic detention time (HRT) and sludge retention time (SRT) can be controlled respectively.
The superiority of membrane bioreactor is mainly manifested in:
1) high to the clearance of pollutant, anti-soil mud swelliong power is strong, and stable effluent quality is reliable, there is no suspension in water outlet.
2) membrane bioreactor has been realized the control respectively of reactor sludge age STR and hydraulic detention time HRT, thereby its design and operation simplification greatly.
3) loss of microorganism has been avoided in the mechanical retention effect of film, can keep high sludge concentration, thereby can improve volume load in bioreactor, reduces sludge loading, has extremely strong impact resistance.
4) because SRT is very long, bioreactor has played again the effect of " mud nitrification tank ", thereby significantly reduces sludge yield, and excess sludge production is low, and Treatment of Sludge expense is low.
5) extend because the effect of damming of film makes SRT, built and be conducive to breed microorganism slowly. As the environment of nitrobacteria growth, can improve the nitrification ability of system, be conducive to improve the treatment effeciency of difficult degradation larger molecular organics and impel it to decompose thoroughly simultaneously.
6) activated sludge of MBR aeration tank can not run off with water outlet, and in running, activated sludge can change because of the variation that enters organic concentration, and reaches a kind of dynamic equilibrium, the feature that this makes system stable water outlet and has anti impulsion load.
7) larger Hydraulic Circulation has caused the even mixing of sewage, thereby makes activated sludge have good dispersiveness, greatly improves the specific area of activated sludge. In MBR system, the high degree of dispersion of activated sludge is to improve another reason of the effect of water treatment. This is that the larger zoogloea of general biochemical method water technology formation is difficult to compare.
8) membrane bioreactor is easy to integratedly, is easy to realize automatic control, convenient operation and management.
9) MBR technique has been omitted second pond, reduces floor space.
