Description
Technical Field
The invention belongs to the technical field of sewage treatment systems, and particularly relates to a domestic sewage treatment system with an oil separation and storage regulation function.
Background
At present, most domestic sewage treatment mainly adopts a BAF process and an MBR process; the main working principle of BAF technology, namely Biological Aerated Filter (BAF), is the oxidative decomposition of microorganisms in a biological membrane adsorbed on a filter material in a reactor, the adsorption and retention effects of the filter material and the microbial membrane, and the graded predation effect of a food chain formed along the water flow direction.
The main drawbacks of BAF process are: the cost is obviously increased: the power consumption of the biological aerated filter in the sewage plant is about 0.11 ℃ per ton of sewage treated. In addition, the quantity of backwashing water is large, the design scale of a sewage plant is 6 ten thousand tons, the quantity of the backwashing water is up to more than 1.3 ten thousand tons at present, the treatment capacity of the sewage plant is reduced, and waste is caused in the aspects of power consumption, medicament addition and the like. The daily management needs to be fine: as BAF inlet water is relatively low in BOD and high in ammonia nitrogen, carbon sources such as methanol and the like need to be added, the adding amount needs to be controlled, and the normal state of microorganisms is guaranteed. The aeration rate needs to be well mastered, the ammonia nitrogen is easily higher due to insufficient aeration rate, and sand grains are washed away due to overhigh aeration rate.
The MBR process, namely a membrane-bioreactor (MBR), is a sewage biological treatment process formed by combining membrane separation and biological treatment technologies, and the bioreactor integrates the advantages of the membrane treatment technology and the biological treatment technology.
The MBR process has the main disadvantages that: firstly, the investment is large, the manufacturing cost of the membrane component is high, and the investment of the project is increased by about 30 to 50 percent compared with the investment of the conventional treatment method; and the membrane module generally has a service life of about 5 years and needs to be replaced due to the expiration, so that the operation cost is high. Secondly, high-strength aeration, high energy consumption caused by large membrane driving pressure for increasing flow speed and mud-water separation for reducing membrane pollution and greatly increased operating electricity cost; meanwhile, the concentration of dissolved oxygen in the backflow muddy water mixture is far too high due to high-strength aeration, and the strict requirements of anoxic denitrification and anaerobic phosphorus removal on the dissolved oxygen are difficult to meet, so that the nitrogen and phosphorus removal effect is poor, and the index requirements of total nitrogen and total phosphorus in effluent cannot be guaranteed. And the processing equipment is more and more complex, and has high requirements on automation of an operating system and operation and maintenance personnel.
Therefore, at present, a large amount of equipment is being built in China aiming at the problems of domestic sewage treatment in residential houses, scenic spots, rural areas and the like. However, the traditional regulation and storage tank does not have the filtering and overflowing functions at the same time, so that the traditional regulation and storage tank has a plurality of inconveniences in use.
