Abstract

The disclosed impulse active biofilter fit to dispersed daily sewage in country and urban distant area comprises: arranging a high-level water tank (1) with a water inlet pipe (12) and a perforated water-distribution pipe (4) on top outside and inside the pond (13) respectively connected by a siphon system (2); under the water-distribution pipe (4), arranging from bottom to top a sludge pipe (10), a mud bucket (9), a deposition zone (8) with an air hole (7) and water outlet pipe (12) on side surface, a water-seepage plate (6), and the filter material (5). This invention has high-efficient treatment capacity, and can reduce energy consumption and equipment complexity.

Description

technical field [0001] The invention is a sewage treatment technology in the discipline of environmental engineering, and is an advanced technology applied to the decentralized domestic sewage treatment in rural areas and urban suburbs. Background technique [0002] At present, biological treatment is the main method of sewage treatment, which can be divided into activated sludge method and biofilm method. Due to the mature technology and reliable equipment, the activated sludge method is widely used in large-scale sewage treatment, but it has the problem of unstable operation and high energy consumption in small and medium-sized sewage treatment. The main forms of biofilm method are: biological filtration, biological turntable and biological contact oxidation method, etc., which are mostly used for small and medium-sized sewage treatment. Due to the characteristics of high treatment efficiency, convenient maintenance and management, and low operating costs, biological filt...
