Abstract
The utility model relates to a biological aerated filter device for treating micro-polluted water, which comprises a tank body, a water inlet pipe, a water outlet pipe and an aerated conduit, wherein the aerated conduit is arranged in the middle of the tank body, a rotary water distributor provided with the water inlet pipe is arranged at the top of the tank body, and the water outlet pipe is arranged at one side of the bottom of the tank body; active filter material I arranged on a bearing plate I is positioned between the rotary water distributor and the aerated conduit; an air pipe is arranged at the bottom of the aerated conduit; on end of the air pipe extends outside the tank wall at one side of the tank body; and active filter material II arranged on a bearing plate II is positioned between the aerated conduit and the water outlet pipe. The biological aerated filter device is divided into two independent regions including an aerobic region and an anaerobic region by the aerated conduit, and nitrifying bacteria can be loaded with high efficiency in the aerobic region, so that the nitration speed is accelerated; in the anaerobic region, controllable release of a carbon source needed by denitrifying bacteria can be realized, so that nitration and denitrification can be carried out with high efficiency, and the aim of improving the efficiency of removing ammonia nitrogen and organic matters in high ammonia nitrogen pollution water can be achieved.
Description
Technical field
The utility model relates to a kind of aeration biological filter device, relates in particular to a kind of aeration biological filter device that is used to handle micro-polluted water.
Background technology
In recent years, along with the sharp increase with urban population of developing rapidly of China's industrial or agricultural, a large amount of trade effluents and sanitary sewage is not treated or it is not up to standard to handle and directly discharge are polluted drinking water source, most of cities and towns, especially with organism and ammonia and nitrogen pollution for very.At present, BAF (BAF) biologic treating technique becomes one of effective means of pretreating micro-polluted source water gradually.But biological aerated filter because the pond one-piece construction is single, is difficult to form environment aerobic on a large scale and the anaerobism coexistence in handling high ammonia nitrogen micro-polluted water process mostly at present, is unfavorable for biological denitrificaion; And the filler that adopts mostly is traditional inorganic carrier, make microorganism under dystrophic environment, activity is low, biofilm is slow, stopping up can appear again in long-play, influences the micro-polluted water treatment effect, in addition, the microorganism of microbial film inside also can be subjected to carrier shielding and mass transfer and diffusion influence, the nutrition scarcity, physiological activity is suppressed, and makes traditional biological aerated filter handle the unstable properties of micro-polluted water.
The utility model content
Technical problem to be solved in the utility model provides a kind of ammonia nitrogen and organic aeration biological filter device that is used to handle micro-polluted water efficiently, stably removed.
For addressing the above problem, a kind of aeration biological filter device that is used to handle micro-polluted water described in the utility model, comprise pond body, water inlet pipe, rising pipe and aerated conduit, it is characterized in that: the middle part of described pond body is provided with described aerated conduit, its top is provided with the turning spurt water device with described water inlet pipe, and its bottom one side is provided with described rising pipe; Be provided with the active filter I that is placed on the supporting plate I between described turning spurt water device and the described aerated conduit; The bottom of described aerated conduit is provided with blast main, and the end of this blast main stretches out described pond body one side pool wall; Be provided with the active filter II that is placed on the supporting plate II between described aerated conduit and the described rising pipe.
Described aerated conduit is provided with several equally distributed aeration heads.
Described turning spurt water device is provided with several equally distributed shower nozzles.
