Abstract
The utility model relates to the technical field of novel aerobic sewage treatment equipment, and in particular relates to a high-efficiency jet biochemical reactor without external air. The high-efficiency jet biochemical reactor comprises a jet-device water inlet, a jet-device air suction port, a jet device, a water discharging area, a water inlet pipe, a water outlet pipe, a jet-device diffusion pipe, a mud-water mixing aeration area and an internal-circulating water outlet pipe, wherein the jet biochemical reactor is two sections of sealed cylindrical containers; and the top of the jet biochemical reactor is provided with the jet device and an exhaust hole. The jet biochemical reactor is characterized in that the bottom of a jet-device throat pipe is connected with the jet-device diffusion pipe. Compared with the prior art, the high-efficiency jet biochemical reactor has the advantages that by improvement on a flow guide barrel of the reactor in the conventional process, an air blocking phenomenon is overcome; the height-diameter ratio of the reactor can be increased; under the condition with same retention time, the occupied area can be effectively redeuced, and simultaneously an external air source is not needed, so that the treatment cost of wastewater in each unit can be reduced. The high-efficiency jet biochemical reactor is long in service life and simple in maintenance.
Description
[technical field]
The utility model relates to a kind of novel aerobic technical field of sewage treatment equipment, a kind of specifically high-efficiency jet biochemical reactor that does not need external air.
[background technology]
Existing HCR technology (High Performance Compact Reactor) is that German Clausthal (Clausthal) college of engineering thing transmits institute mutually in eighties invention; This technology has merged when high-speed jet aeration, thing strengthens technology such as transmission, turbulent shear mutually; And have deep well aeration and liquefaction sewage sludge bed characteristics; Therefore the transformation efficiency of its atmospheric oxygen is high; The volumetric loading of reactor drum is big, and hydraulic detention time is short, is the current a kind of high-efficiency aerobic bioremediation that western countries accepted extensively of being.
Yet there are some problems in this technology in actual moving process, as exists gas to block up phenomenon; Be the jet water outlet because top hole pressure can't reach the guide shell bottom inadequately, the slough is then formed on the guide shell bottom, and sewage forms short stream in reaction tank; The residence time shortens, and water outlet can't reach production engineering specifications, in order to solve the stifled problem of gas; Just need external air, can further increase the unit consumption of energy of wastewater treatment like this; And after handling water yield increase, reactor drum can't be accomplished larger ratio of height to diameter, and it takes up an area of little advantage and can't embody fully.
[summary of the invention]
The purpose of the utility model is the deficiency that solves prior art, provides a kind of and effectively saves floor occupying area, and does not need the high-efficiency jet biochemical reactor of external air source.
For realizing that above-mentioned purpose designs a kind of high-efficiency jet biochemical reactor; Comprise ejector water-in, ejector suction opening, ejector, exhalant region, water inlet pipe, rising pipe, ejector diffuser tube, muddy water mixed aeration district, internal recycle rising pipe; The jet biochemical reactor is the cylindrical vessel of two sections sealings; Jet biochemical reactor top is installed ejector and is had a venting hole, it is characterized in that ejector trunnion bottom connects the ejector diffuser tube.
Described jet biochemical reactor top is exhalant region, and the bottom is muddy water mixed aeration district.
Described exhalant region one side bottom is provided with rising pipe.
Described muddy water mixed aeration district one side is provided with water inlet pipe.
Described muddy water mixed aeration district one side bottom is provided with the internal recycle rising pipe.
The utility model is compared with prior art, and the improvement through to reactor drum guide shell in the existing technology changes it into ejector diffuser tube, will directly deliver to reactor bottom through the air water mixed solution that ejector is squeezed into, thereby overcomes the stifled phenomenon of gas; But the aspect ratio of the utility model augmenting response device under the situation of the equal residence time, can effectively be saved floor space; Simultaneously, do not need external air source, then can reduce the processing costs of unit waste water; This high-efficiency jet biochemical reactor long service life, easy to maintenance.
[description of drawings]
Fig. 1 is the structural representation of the utility model;
Among the figure: 1 is that ejector water-in, 2 is that ejector suction opening, 3 is that ejector, 4 is that exhalant region, 5 is that water inlet pipe, 6 is that rising pipe, 7 is that ejector diffuser tube, 8 is that muddy water mixed aeration district, 9 is the internal recycle rising pipe.
[embodiment]
In conjunction with accompanying drawing the utility model is further specified, the manufacturing technology of this device is very clearly concerning this professional people.
Shown in accompanying drawing 1; A kind of high-efficiency jet biochemical reactor; Form by ejector water-in, ejector suction opening, ejector, exhalant region, water inlet pipe, rising pipe, ejector diffuser tube, muddy water mixed aeration district, internal recycle rising pipe; The jet biochemical reactor is the cylindrical vessel of two sections sealings, and jet biochemical reactor top is installed ejector and had a venting hole, and ejector trunnion bottom connects the ejector diffuser tube.Jet biochemical reactor top is exhalant region, and the bottom is muddy water mixed aeration district.Exhalant region one side bottom is equipped with rising pipe.Muddy water mixed aeration district one side is equipped with water inlet pipe, in its bottom the internal recycle rising pipe is installed.
In order to solve the stifled phenomenon of gas; The setting of cancellation jet pipe guide shell; And adopt a diffuser tube to link to each other with the ejector trunnion, and getting into diffuser tube after circulating sewage and the air mixed, the liquid that gets into diffuser tube charges at self flow velocity and follow-up under the pressure effect of diffuser tube liquid and can only flow straight down; The diffusion mouth of pipe place that is positioned at reactor bottom up to arrival gets into reactor drum, exists gas to block up the shortcoming of phenomenon thereby overcome guide shell.In addition, reactor bottom is provided with the internal recycle water outlet, and water outlet here will mix after jet-pump is delivered to ejector entering reactor drum in the mud that is refluxed by second pond, form the internal recycle of sewage in the reaction tank.Sewage after the processing to the exhalant region that is positioned at reactor drum top, is discharged overflow through rising pipe.
