Micro-power sewage treatment method and device

Abstract

The invention discloses a micro-power sewage treatment method and device. The treatment device comprises a physicochemical pretreatment unit, a biochemical treatment unit, a sedimentation tank, a filter tank and a post-treatment unit which are connected in sequence, and the treatment device further comprises an air blower.According to the scheme, the low-power air blower is ingeniously arranged as an air stripping power source for sewage treatment, the condition that the single one-to-one matching power device is required in the traditional scheme is abandoned, such that the sewage treatment energy consumption is low, the cost is low, and the equipment maintenance is simplified; and in addition, the low-power air blower is connected to the biochemical treatment unit, the sedimentation tank and the filtration tank through the plurality of air conveying pipes so as to achieve the stirring, the backflow, the aeration, the sludge discharge and other functions, so the process principle of small sewage treatment is fully embodied. The sewage treatment process method has the advantages of simple structure, low energy consumption, low sludge yield, stable effluent quality and the like.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a microdynamic sewage treatment method and a treatment device. Background technique [0002] As my country's environmental protection requirements become more and more stringent, in most cases, some small amounts of sewage are also required to be treated and discharged up to standards, such as: scattered crowds (rural areas or residential areas, etc.) or activity areas (highway service areas) or resorts, etc.), sewage discharged from small hospital outpatient clinics, small catering sewage, car wash wastewater, small beauty salon sewage, foot bath health sewage, etc.; the existing sewage treatment process or device needs more auxiliary equipment to assist Sewage treatment, therefore, requires more maintenance and operation costs and management personnel allocation, and based on economic, management and efficiency issues, traditional sewage treatment devices are not suitabl...
