Problems solved by technology

However, the biofilter itself provided by the present invention is still relatively easy to block and requires frequent backwashing. When backwashing the biofilter, first close the valve of the waste water inlet pipe, and then use clear water to carry out the aerated biofilter. Backwashing not only wastes water and gas resources, but also reduces the efficiency of wastewater treatment

Abstract

The invention provides a biomembrane reactor, which comprises an outer cylinder with a water inlet and a water outlet provided at the bottom part; an inner cylinder arranged in the outer cylinder, two ends of the inner cylinder are communicated with the outer cylinder, the top of the inner cylinder is lower than the top of the outer cylinder; a filling material used for filling a bio-contact oxidation tank of the inner cylinder; a filter material used for filling the biological filter tank between the inner cylinder and the outer cylinder; an aeration apparatus provided at the bottom of the outer cylinder, the aeration apparatus is communicated with the inner cylinder. The invention provides a waste water treating system and a method for treating waste water. The biomembrane reactor provided in the invention has the functions of the bio-contact oxidation tank and the biological filter tank, waste water forms a circulation between the inner cylinder and the outer cylinder under the promotion effect of the aeration apparatus, and waste water passes through the filling material used for bio-contact oxidation tank and the filter material used for biological filter tank for a purifyingprocess, thereby the effect of treating waste water can be improved.

Description

technical field [0001] The invention belongs to the technical field of wastewater treatment, and in particular relates to a biofilm reactor, a wastewater treatment system and a wastewater treatment method. Background technique [0002] Sewage treatment or wastewater treatment refers to the process of purifying wastewater or sewage by physical, chemical or biological methods to make it meet the discharge or recycling standards. It is widely used in construction, agriculture, transportation, energy, petrochemical, environmental protection, and urban landscape. , medical, catering and other fields. [0003] Biofilm method is a commonly used wastewater biological treatment technology, which mainly uses microorganisms attached to the surface of solid media to treat organic wastewater. Biofilm is an ecosystem composed of highly dense aerobic bacteria, anaerobic bacteria, facultative bacteria, fungi, protozoa and algae, and the solid medium attached to it is called filter material...
