Abstract
The invention discloses a method and a device for improving the treatment efficiency of a biological filter. The method comprises the following steps of: pumping part of discharged water at the water outlet of the biological filter with different fillers to the inlet of the biological filter by using a water pump; and mixing the part of water and sewage to be treated together for treatment. The water outlet is connected with a backflow connecting opening and a backflow valve; a backflow pipeline and a backflow pump are connected between the backflow connecting opening and a water inlet; and the biological filter comprises an aeration biological filter with different fillers, an anaerobic biological filter and a biological activated carbon filter. The method and the device have the advantages that: the pump is added after water discharge to make half treated water flow back to the front end of equipment; the content of oxygen in the treated water is extremely high, so that a denitrification treatment effect can be greatly improved after the backflow and energy can be save by more than 30 percent; and nitrate nitrogen in a system can be fed to the front end of the equipment to perform denitrification reaction in the system, is reduced to nitrogen and then is discharged out of the system to increase the denitrification capability of the system.
Description
Technical field
The present invention relates to a kind of method and apparatus that improves the biological filter processing efficiency, is a kind of waste disposal plant that adopts BAF, anaerobic biofilter or the biological activated carbon filter of different fillers.Be mainly used in polluted river water, the improvement of lake, little pollution river, also can be used for high-quality regeneration waterworks construction.
Background technology
In the prior art, the BAF, anaerobic biofilter or the biological activated carbon filter that adopt different fillers are in the sewage water treatment method, oxygen level in the water after the processing is very high, the very high water of this oxygen level directly emits, and in the treating processes of biological filter, need aeration to increase oxygen level in the water to water, it is higher to consume energy.
Summary of the invention
The present invention aims to provide a kind of method and apparatus that improves the biological filter processing efficiency, utilizes the oxygen level in refluxing, and reduces aeration, solves the power consumption problem of higher that prior art exists.
Technical scheme of the present invention is:
A kind of method that improves the biological filter processing efficiency is characterized in that, the part water outlet of the biological filter water outlet of different fillers is incorporated into the inlet of biological filter with water pump, converges to processed sewage and handles; Described biological filter comprises BAF, anaerobic biofilter and the biological activated carbon filter of different fillers.
A kind of device that improves the biological filter processing efficiency, the biological filter that comprises different fillers, be respectively equipped with water-in and water outlet at the two ends of this biological filter, at this water-in and water outlet inlet valve and flowing water Valve are housed respectively, it is characterized in that, be connected to backflow interface and return valve at described water outlet, between this backflow interface and described water-in, be connected with reflux pipeline and reflux pump.
Described biological filter comprises BAF, anaerobic biofilter or biological activated carbon filter.
Also be provided with the backflow automatic control device, comprise controller and oxygen sensor, described return valve is an electric control valve, and oxygen sensor is installed in the described biological filter, is connected the control end of oxygen sensor and electric control valve respectively at the input terminus and the output terminal of this controller.
Advantage of the present invention is: add pump after the water outlet half treated water is back to front equipment end, effectively improved removal effect of organic matter in the sewage, for aerobic filter tank system, because of the oxygen level in the treated water very high, can improve the denitrogenation processing effect greatly after the backflow, and energy-conservation more than 30%.Also the nitric nitrogen in the system can be delivered to front equipment end, carry out anti-nitration reaction in system, to nitrogen, the discharge system increases system's denitrogenation ability with nitrate-nitrogen reduction.
