Abstract
The utility model discloses a sewage treatment biological reaction tank capable of enhancing the internal circulation. The sewage treatment biological reaction tank comprises an air blower, an aeration pipe, a water distribution pipe, a nutrient solution chemical-adding device, a stirrer, a horn-shaped cylinder and a reaction tank body, wherein the air blower is connected with the aeration pipe at the bottom of the reaction tank body through a pipeline; the water distribution pipe is arranged below the aeration pipe; the horn-shaped cylinder is arranged inside the reaction tank body. According to the utility model, the sewage treatment technology is optimized, the internal circulation in the biological reaction tank is enhanced, and the oxygenating efficiency is improved; the reaction tank adopts a sewage treatment biochemical reaction tank system with fewer reactors, fewer procedures, small occupied area and high efficiency, and utilizes the internal circulation denitrification technology to perform nitrogen removing and dephosphorizing on sewage.
Description
Technical field
the utility model relates to technical field of sewage, is specifically related to a kind of reinforcement internal recycle sewage disposal biological reaction tank.
Background technology
Biological sewage treatment is mainly converted into simple inorganics by the Decomposition of microorganism organism in sewage, and sewage is purified, by can be divided into anaerobic biological treatment and the large class of aerobic biological treatment two to oxygen demand situation.In sewage treatment process, to nitrogen phosphorus, remove particularly important, the Eutrophication of the water body that nitrogen phosphorus excessive emissions has caused, still that water pollutes the significant problem existing, sewage disposal no longer only take that to remove organism be object, but should remove organism denitrogenation dephosphorizing again, reduce water body Eutrophication, traditional Biological Nitrogen Removal Processe, though generally there is Nitrogen/Phosphorus Removal, but reactor is many, complex process, energy consumption is high, in order to obtain good Nitrogen/Phosphorus Removal simultaneously, need to increase sludge reflux or additional carbon, not only increased process operation expense, and produced a large amount of excess sludges.The stirring of biological reaction tank inside and oxygenation affect the effect of disposing of sewage.
Utility model content
The purpose of this utility model is to provide a kind of reinforcement internal recycle sewage disposal biological reaction tank, optimize the technique of sewage disposal, strengthen biological reaction tank internal recycle, improved oxygen-transfer efficiency, this is the sewage disposal biochemical reaction cell system that a kind of reactor is few, step is few, floor space is little, efficiency is high, utilizes internal circulation denitrification technology to carry out denitrogenation dephosphorizing processing to sewage simultaneously.
The purpose of this utility model is achieved through the following technical solutions: a kind of reinforcement internal recycle sewage disposal biological reaction tank, comprising: gas blower, aeration tube, water distributor, nutritive medium chemicals dosing plant, stirrer, speaking trumpet, reaction tank; Described gas blower is connected with the aeration tube of reaction tank bottom by pipeline; Described water distributor is arranged on the below of aeration tube; The inside of described reaction tank is provided with speaking trumpet.
Described nutritive medium chemicals dosing plant is connected with nutritive medium chemical feed pipe by pipeline.
The center of described speaking trumpet is provided with stirrer.
Principle of work of the present utility model: the sewage of processing through equalizing tank enters reaction tank by lift pump suction, by water distributor, be evenly distributed on reaction tank bottom, after starting stirrer, reaction tank forms reinforcement internal recycle, sewage contacts with the active sludge in reaction tank, by gas blower, to reaction tank, blast air, aeration tube is micro-bubble by air dispersion, increased the dissolved oxygen in water, utilize the adsorption of active sludge and the metabolism of microorganism to reach the object of purifying waste water, microorganism in active sludge under the condition of aerobic by a part of organism in sewage for the synthesis of new cell, another part organism is carried out to katabolism to obtain the synthetic required energy of cell, its final product is the stable materials such as carbonic acid gas and water, internal circulation denitrification carries out denitrogenation dephosphorizing processing to sewage.
Compared with prior art, the utlity model has following beneficial effect: the utility model is optimized the technique of sewage disposal, can shorten the technical process of sewage disposal, stirrer and speaking trumpet structural strengthening biological reaction tank internal recycle, improved oxygen-transfer efficiency, this is the sewage disposal biochemical reaction cell system that a kind of reactor is few, step is few, floor space is little, efficiency is high; Sewage distributes from bottom even, and sewage contacts with the active sludge in reaction tank, utilizes internal circulation denitrification technology to carry out denitrogenation dephosphorizing processing to sewage simultaneously, reduces traditional sludge and refluxes.
