Description of the Invention (/) Field of the Invention The present invention relates to a sewage treatment method and system, which uses biological treatment to make sewage after treatment, and its water quality can reach the national discharge standard, and no sludge discharge will occur. Deal with the problem. BACKGROUND OF THE INVENTION In the application of conventional traditional sewage treatment systems to environmental workers, most of them use fixed biofiltration membranes, or contact wastewater with biofilms grown on contact materials, thereby achieving the effect of sewage treatment. Wastewater treatment using such fixed biofilms. Generally speaking, the reaction membranes in traditional sewage treatment systems lack natural circulation and are preliminarily decomposed in a natural decay manner, resulting in a serious situation of sludge sedimentation. On the other hand, when the growth trend of the reaction tank in the traditional sewage treatment system reaches the death stage, it will cause the reduction of microbial activity and its system energy, and promote the formation of a large number of rubber plumes, causing a secondary source of sludge. Therefore, there is a need for a novel wastewater treatment method and system that meets national discharge standards and does not generate secondary sources of sludge. SUMMARY OF THE INVENTION Therefore, the object of the present invention is to provide a sewage treatment method and a system thereof, which use biological treatment without any chemical or medicinal treatment, so that after the treatment, the water quality reaches the national discharge standard To avoid the secondary pollution caused by chemical agents and the problem of sludge discharge treatment. 0 In order to achieve the above-mentioned purpose, a sewage treatment method according to the present invention is provided, which includes: The paper size is applicable to the Chinese National Standard (CNS) A4 specification ( 210 X 297 mm) (Please read the notes on the back before filling this page)

Description of the invention (f) Description of the invention The main principle of the biological wastewater treatment method and system of the present invention is based on the fact that in the reaction tank, several or more microorganisms with different functions are attached to the biological material. In the presence of the aeration tube, through the proper placement of the aeration tube and the resulting circulation convection, a natural environment area can be created in the reaction tank. The simulated ecosystem can be divided into convection areas (areas with high oxygen content), no convection areas at the corners of the reaction tank (almost no oxygen content), and areas at the junction of the two areas (high oxygen content) The best living environment for the microbiota at the corner of the reaction tank), so that different microorganisms can breathe or ferment carbohydrates for further digestion. Therefore, in the method of the biological treatment method of the present invention, as long as the sewage passes through, a large number of bacterial groups are generated, among which, for example, bacilli and cocci play a special decomposition role. Because of its residential effect, it is not easy to discharge with water, so its function is quite stable and durable. This sewage treatment method comprehensively purifies the polluted organic sewage, so there is no secondary pollution of sludge. The biological treatment method used in the present invention has the following effects: 1. Cultivation is beneficial to the environmentally beneficial biomes, non-toxic, harmless to humans and animals, non-corrosive, and safe. 2. The tank is equipped with ultra-micro exposure equipment, which has a gas-lifting effect and will agitate the wastewater sufficiently, and has super high dissolving acid efficiency, and can inhibit the growth of spoilage bacteria and promote the reproduction of fermentation bacteria. 3. Micro-aerobic and extremely small-scale aerobic bacteria that naturally adapt to their environment are produced in the tank. There are no large-scale aerobic bacteria, so there is almost no sludge. 4. There are many microorganisms per unit area and there are many biological phases. ____7__________ This paper size applies to China National Standard (CNS) A4 (210 X 297 mm) (Please read the precautions on the back before filling this page)
