Abstract
The invention discloses a novel jet aerator. The novel jet aerator comprises an inlet flange, an outlet flange and a suction chamber, wherein air inlets, sprayers and diffuser pipes are installed around the suction chamber; the sprayer openings of the sprayers directly face the pipe openings of the diffuser pipes. The novel jet aeration process comprises the following steps that by taking a backflow sludge pump as a power device, and an active sludge mixture of a secondary sedimentation tank as a jet medium, the jet medium and oxygen are converged by the novel jet aerator; sludge is activated, so that sludge treats pollutants contained in waste water in a biological aeration tank; after the sludge in the biological aeration tank and the pollutants in waste water are treated and separated by the secondary sedimentation tank, the active sludge mixture enters the novel jet aerator through the backflow sludge pump, and cycling in the way, waste water is treated. The novel jet aerator provided by the invention has the advantages that during the operation process, the novel jet aerator is high in air suction quantity, high in oxygen conversion rate, convenient to install and maintain, wide in tank shape adaptability, and is beneficial to flow pushing and stirring.
Description
Technical field
The present invention relates to the jet aerator in sewage disposal biochemical system, relate in particular to a kind of Novel jet aerator.
Background technology
Tradition jet aerator inspiratory capacity under natural aspiration mode is not enough, and increase inspiratory capacity, be generally to increase water pump power and jet aerator quantity, and increase blower equipment, tradition jet aerator is all single Venturi ejector, difference is the large and little of Venturi ejector, when Venturi ejector do larger time, exist gas and water engaging surface little, cause inspiratory capacity and oxygen transfer rate to reduce, tradition jet aerator is generally contained under the water surface, installation and maintenance inconvenience, applicable pond shape scope is less, is unfavorable for plug-flow and stirring.
Summary of the invention
The object of this invention is to provide that a kind of inspiratory capacity is large, OTR is high, convenient for installation and maintenance, adaptation pool shape scope is wide, is beneficial to the Novel jet aerator of plug-flow and stirring.
For achieving the above object, the technical solution adopted in the present invention is:
A Novel jet aerator, its feature is: comprising: suction flange, discharge flange and suction chamber, described suction chamber is installed into gas port, nozzle and diffuser pipe around, and the jet hole of described nozzle is over against the mouth of pipe of described diffuser pipe.
According to above-mentioned Novel jet aerator, its feature is: described suction chamber number is 1.
According to above-mentioned Novel jet aerator, its feature is: the number of described inlet mouth is 1～2.
According to above-mentioned Novel jet aerator, its feature is: described nozzle number equates with the number of diffuser pipe, and number is 2～100.
According to above-mentioned Novel jet aerator, its feature is: described discharge flange is installed supervisor and arm, and supervisor and arm are arranged under the water surface, and arm end is installed flat nozzle.
A kind of novel jet flow aeration system, its feature is: technological process is as follows: take return sludge pump as power set, using the active sludge mixture of second pond as jet media, pass through Novel jet aerator, jet media and oxygen converge, activate mud, make the pollutent that in sludge treatment biological aeration tank, waste water contains, mud in bio-aeration pool and Pollutants in Wastewater are again after the processing of second pond is separated, active sludge mixture enters Novel jet aerator through return sludge pump again, so circulation, carries out wastewater treatment.
Advantage of the present invention is: the present invention in the course of the work, adopt active sludge mixture as jet working medium, active sludge mixture is entered in the present invention with after air amount violent mixing effect is occurred by suction flange, mixing effect carry out on the one hand gas-liquid-solid between turbulent fluctuation diffusion and energy exchange, and gas-liquid-solid three alternate transfer processes, more outstanding is to occur in by a high speed violent turbulent fluctuation " to cut " to obtain very trickle bubble in addition, active sludge molecule, the jet working medium of a plurality of nozzle ejections mixes with gas at suction chamber, compare traditional jet aerator and increased contact area, and then increase inspiratory capacity and OTR, and then increase active sludge Surface Renewal rate and adsorption surface area, thereby make in the tiny cotton-shaped physical efficiency of active sludge and bubble organism in oxygen and waste water have abundant Contact-sorption effect, improved treatment effect, and the present invention is arranged on above the water surface, facilitate the maintenance of equipment, discharge flange is installed supervisor and arm, supervisor and arm are arranged under the water surface, arm end is installed flat nozzle, applicable square, circular, installation and the transformation of rectangle and irregular pond shape, and the fan-shaped fluid of high speed that flat nozzle forms, when improving oxygen transfer efficiency, play good plug-flow and stirring action.
