Problems solved by technology

The problems brought by these processes are: the septic tank covers a large area, and the land resources are limited, so the feces need to be cleaned frequently
4. Natural strains start slowly, have poor load impact resistance, and have relatively poor treatment effect on ammonia nitrogen

Abstract

The invention discloses a wastewater treatment device using dominant bacteria. The device comprises an efficient fluidized-state aerobic digestion tank, a contact oxidation tank, a settling tank and a biological adsorption tank which are sequentially connected, wherein the efficient fluidized-state aerobic digestion tank comprises an aerobic digestion reaction zone, filler and multiple baffles for turbulence are arranged in the aerobic digestion reaction zone, and multiple aeration heads for driving domestic wastewater of the aerobic digestion reaction zone to produce rotational flows are also arranged in the aerobic digestion reaction zone. The wastewater treatment device using the dominant bacteria efficiently treats domestic wastewater containing suspended solids under the aerobic condition, works stably and occupies a small area, and a wastewater treatment technology using the dominant bacteria treats the domestic wastewater containing the suspended solids by using the wastewater treatment device using the dominant bacteria.

Description

technical field [0001] The invention relates to the field of waste water treatment equipment, in particular to a waste water treatment process and device utilizing dominant strains. Background technique [0002] With the development of industry and the increase of population, the process of urbanization is getting faster and faster. Especially in recent years, the real estate industry has developed rapidly, and living quarters have been built rapidly. However, due to limited land resources in the city, some communities are built near the suburbs, which often leads to inadequate urban pipe network construction. According to the document requirements of Guangdong Province in 2008, corresponding wastewater treatment facilities must be provided in these communities. [0003] In the past wastewater treatment technologies with suspended solids, such as domestic sewage, septic tanks were installed first, and then biochemical treatment was performed. The problems brought about by ...
