Description
Technical field
The utility model relates to sewage work's sewage aerobic biochemical processing, relates in particular to a kind of folliculus aerating system automatically.
Background technology
Aeration is a kind of means that air is contacted strongly with water, and its object is airborne oxygen to be dissolved in the water, or unwanted gas and volatile matter in water are banished in air.In other words, it is a kind of means that promote exchange of substance between gas and liquid.It also has some other vital role, as mixed and stirring.Airborne oxygen is delivered in water by aeration, and oxygen carries out mass transfer transfer by gas phase to liquid phase, the theory of this mass transfer diffusion, and applying at present more is two-film theory.
Two-film theory is thought, on " air-water " interface, exists air film and liquid film, and the outer and liquid film of air film has air and liquid-flow outward, genus turbulent state; Between air film and liquid film, belong to laminar flow regime, do not have convection current, there will be pressure gradient and concentration gradient under certain condition.If the concentration of oxygen is lower than the saturation concentration of water oxygen in liquid film, airborne oxygen continues to see through liquid film to internal diffusion and enters water body, thereby liquid film and air film will become the barrier that oxygen transmits.Obviously, overcoming liquid film, to hinder effective means be Fast transforms " solution-air " interface.Just so, concrete way is exactly aeration agitation: reduce the size of bubble, increase the quantity of bubble, improve the turbulence level of liquid, strengthen the fitting depth of aerator, extend the duration of contact of bubble and liquid.Aerator is widely adopted in sewage disposal based on this way just.
Aeration tank of the prior art is mainly by there being two kinds of blast aeration tank and mechanical aeration basins.
Blast aeration claims again pressurized air aeration, is mainly made up of Aeration fan and special aerator.Adopt aeration tank in this way, mostly be rectangle concrete sump, be divided into the compartment of several independent water inlets in pond with partition wall, each compartment is divided into again several gallerys.Sewage enters behind pond and in gallery, flows in turn, discharges to the other end, is transported to the air-diffuser being located at the bottom of pond with air compressor by pipeline, becomes bubble disperse and overflows, and at liquid-gas interface, oxygen is dissolved in water.Dispersion device has four kinds of different types such as perforated tube, fixing spiral aerator, water sprayer and micropore diffuser plate.
Mechanical aeration is generally to utilize the mechanical wheel rotation being contained in aeration tank, and waste water in vigorous agitation pond, dissolves in water airborne oxygen.Impeller is contained in waste water surface in pond and carries out the energy-conservation of aeration, is called surface aeration.This device, by the hydraulic Lift of impeller, impels waste water in pond constantly to circulate, and constantly updates gas-to-liquid contact face to increase oxygen absorbed.When vane rotary, form hydraulic jump at periphery, can effectively entrain into air; Blade rear side produces negative pressure, can air amount, so inflation effect is better.Impeller immersed depth and rotating speed can regulate, to ensure best effect.Typical mechanical aeration basin has circular surface aero-accelerator, standard type aero-accelerator, IO type aero-accelerator and square aero-accelerator etc.Two kinds of methods of blast aeration and mechanical aeration sometimes also can coupling, and to improve oxygenation capacity, this is applicable to the sewage that organic concentration is higher.
But in the process of aeration, can produce a large amount of microorganism foams.Foam spreads on walkway board and can impact safeguard normally, even can freeze in winter, clears up very difficult.In addition foam can form unpleasant odor, serious environment pollution.
