Background technology
Along with social development, the problem of water scarcity is day by day serious, and water will become an important factor of restriction social development.People also more and more pay attention to exploitation and the improvement of water technology.
Biologic process for treating sewage is one more special in sewage treatment process, is called again activated sludge process.Activated sludge process can be divided into aerobic method and anaerobic process etc.In aerobe Sewage treatment systems, microorganism utilizes the dissolved oxygen in water, and then the organic pollutant in oxidative degradation water carries out the lock out operation of microorganism and water, reaches the object of purifying waste water.Dissolved oxygen English name is Dissolved Oxygen, is conventionally denoted as DO, refers to the content that is dissolved in oxygen in water, with oxygen in every premium on currency milligram a number represent, unit is mg/L.The number of oxygen in water is a very important index in bio sewage treating process.
In order to make microorganism in water obtain enough dissolved oxygens, people utilize gas blower pressurized air or are stirred in water and inflated by surface.For microorganism provides the air-blowing device of oxygen and supporting pipeline, stationary installation etc., be referred to as aerating apparatus.Aerating apparatus is generally divided into end device and the table device that exposes to the sun that exposes to the sun, and the end device that exposes to the sun has disk-type aeration device, tubular type aerating apparatus etc., and table exposes to the sun and is divided into expose to the sun device and to turn brush be the table system etc. of exposing to the sun of inversed umbrella type table.
The end device that exposes to the sun is generally introduced gas blower pressurized air by blast connection, by the aerator installed at the bottom of aeration tank by oxygen containing air diffuser in air, make the microorganism in aeration tank obtain oxygen.In existing aeration process, in general one group of aeration tank, there are several groups of gas manifolds, every group of arm connects some aeration tubes or aeration plate, control the aeration aerating in a certain region, aeration tank, and gas manifold valve is generally normally open, do not adjust, and aeration plate or aeration tube are generally micro-pore aeration, after long-time use, microbial film is easily grown in the pollution that surface or micropore are subject to mud in water, thereby cause the obstruction of aeration tube or aeration plate, make its aeration deleterious, final damage some or several aerators causes the aeration of whole group of aeration tank undesired, cause water outlet to worsen, force the replacing of carrying out aerator.And if traditional aerating apparatus needs to change, need out of servicely, and the water in aeration tank is emptied overhaul replacings, not only impact production normally, and maintenance and repair is with high costs.
