Abstract
The utility model relates to a device for improving the treatment efficiency of biological filters. Partial outlet water of water outlets of the biological filters with different filling materials is introduced to inlets of the biological filters though water pumps, and is merged with sewage to be treated for carrying out treatment, the water outlets are connected with backflow interfaces and backflow valves, backflow pipelines and backflow pumps are connected between the backflow interfaces and the water inlets, and the biological filters comprise an aeration biological filter, an anaerobic biological filter and a biological activated carbon filter with different filling materials. The utility model has the advantages that after water outlet, the pumps are added for flowing half of treated water back to the front end of equipment, because the oxygen content in the treated water is very high, the nitrogen removal treatment effect can be greatly improved after the back flow, and more than 30 percent of energy can be saved. Nitrate nitrogen in a system can be conveyed to the front end of the equipment for carrying out nitration reaction in the system, the nitrate nitrogen can be reduced into nitrogen gas to be exhausted out of the system, and the nitrogen removal capability of the system is improved.
Description
Technical field
The utility model relates to a kind of device 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 utility model aims to provide a kind of device 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.
The technical solution of the utility model is: 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.
The utility model has the advantages that: 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.
