Macromolecule oxygen supply system

Technical Field

The invention belongs to the technical field of sewage treatment equipment, and particularly relates to a polymer oxygen supply system.

Background

Because of increasingly serious pollution, the social demand for water environment protection is increasingly increased, stricter requirements are put forward on the discharge standards of water quality indexes such as organic matters, ammonia nitrogen, total phosphorus and the like in sewage, and the biofilter is widely applied to advanced treatment and upgrading transformation of municipal sewage, low-concentration industrial wastewater, polluted raw water and tap water at present. The biological filter is a biological treatment structure formed by broken stones or plastic fillers, and sewage is in contact with microbial films growing on the surfaces of the fillers in a clearance mode, so that the sewage is purified. The biological filter is developed through an original intermittent sand filter and a contact filter based on the principle of soil self-purification on the basis of the practice of sewage irrigation, and specifically comprises a water distribution system, an air distribution system, a backwashing system, a pressure bearing layer, a biological filter material and the like, is a microorganism growth system, and removes biodegradable and utilizable soluble substances through the physical interception of the biological filter material and the adsorption, absorption, degradation, oxidation, synthesis and other effects of microorganisms attached to biological filler; the biological filter can be divided into an aerobic biological filter, a facultative biological filter and an anaerobic biological filter according to different dissolved oxygen concentrations in water in the biological filter caused by different aeration strengths; under different dissolved oxygen concentrations, biochemical functions of the biological filter are different; the aerobic biofilter has high dissolved oxygen and a large amount of heterotrophic bacteria, can effectively remove organic matters and ammonia nitrogen in the wastewater, has a certain removal effect on total nitrogen, and requires certain energy consumption for aeration; the dissolved oxygen in the anoxic biological filter is generally 0-1mg L-1, the dissolved oxygen in the anaerobic biological filter is generally 0mg L-1, and under the condition that a carbon source, ammonia nitrogen, nitrite nitrogen or nitrate nitrogen exists, a shortcut nitrification-denitrification reaction, a nitrification-denitrification reaction or an anaerobic ammonia oxidation reaction can be carried out, so that the ammonia nitrogen, total nitrogen and organic matters in water can be effectively removed at the same time.

At present, structural optimization is mostly performed on the whole biological filter, for example, a document with the publication number of CN209468176U discloses a biological filter, which comprises a water distribution layer, a filter material layer, a supporting layer and a water collection layer which are sequentially distributed from top to bottom, sewage to be treated enters the water distribution layer to be uniformly distributed, organic nitrogen and ammonia nitrogen entering the filter material layer are converted into nitrate nitrogen through actions of ammoniation, nitrification and the like, the supporting layer blows air in a dry period to ensure the activity of aerobic bacteria in the filter material layer, the nitrate nitrogen is further removed in the water collection layer through denitrification by utilizing a raw water carbon source, and the obtained purified water meets the first-level A standard. The biofilter has the advantages of low investment and low operation cost, adopts a raw water carbon source to carry out post denitrification, and has better sewage treatment effect by controlling the flow of sewage in a water distribution pipe and an overrunning pipe. However, in the scheme, the fillers in the filter material layer are often loaded by the net bags and are directly stacked on the supporting layer, and the net bags are irregularly arranged and are easy to crack, so that the microbial activity is influenced.
