Description
Technical Field
The utility model relates to a rural domestic sewage treatment technical field, especially a rural domestic sewage treatment integration equipment.
Background
In recent years, the country vigorously promotes new rural construction, and the synchronous development of rural economy and environment also becomes necessary. Residents in rural areas are relatively dispersed, the development degrees of different areas are different, and the quality of domestic sewage is different to a certain extent, so that sewage treatment facilities are required to have adaptive change capacity, strong impact load resistance and simple and convenient operation and maintenance.
The existing sewage treatment methods mainly comprise an activated sludge method and a biomembrane method. The activated sludge process is mature, but has large occupied area, high capital cost and easy influence of water quality and water quantity change on the operation effect. The biofilm method is widely used in small-scale dispersed sewage treatment, and comprises a biofilter, a biological rotating disc method, a biological contact oxidation method and an aerobic biological fluidized bed method. The microorganisms participating in purification reaction in various biomembrane processes are various and easy to survive, and meanwhile, the method has strong adaptability to water quality and water quantity changes. However, the biofilm method has its own defects, such as that the carrier filler in the biological fluidized bed reactor can only play a role in a fluidized state, the process stability is poor, the filter material in the biological filter tank is easy to block, periodic back flushing is required, and simultaneously the filler is fixed and the aeration equipment under the filler is difficult to replace.
Moving bed biofilm reactors (MBBR process) are a novel biofilm reactor, and are improved novel composite biofilm reactors developed on the basis of fixed bed reactors, fluidized bed reactors and biofilters. The method overcomes the defects that a fixed bed reactor needs regular back flushing, a fluidized bed reactor needs carrier fluidization, a biological filter is blocked and needs to be cleaned, and the aerator needs to be replaced, and also keeps the characteristics of impact load resistance, low sludge yield and long sludge age of the traditional biomembrane method. Compared with the activated sludge method, the method has longer sludge age, can keep more nitrifying bacteria and has better denitrification effect. The main principle is that a certain amount of suspended filler is added into a reactor, sewage continuously flows through the suspended filler of the reactor to form a biological membrane on the filler, anaerobic bacteria, anoxic bacteria and aerobic bacteria grow on the inner layer, the middle layer and the outer layer of the biological membrane for the second time, the suspended filler freely moves in the reactor under the action of the convolution and overturning of mixed liquor, and microorganisms propagate and grow on the biological membrane in large quantities and degrade organic pollutants in the sewage, so that the effect of purifying the sewage is achieved. As a process combining an activated sludge method of suspension growth and a biological membrane of attachment growth, the MBBR method has the advantages of both: small occupied area, no need of circulating back flushing because microorganisms are attached to the carrier and flow along with water flow, high organic load, high impact load resistance and easy operation and management. However, the existing MBBR sewage treatment equipment is relatively single in form and low in integration.
