A landscape type combined sewage treatment equipment and its method

Abstract

The invention discloses landscape type combined sewage treatment equipment and a method thereof. The equipment falls into an underground unit and an overground unit. The underground unit is sequentially partitioned into a grid, an adjustment tank, a sludge tank, an anaerobic tank, an aerobic tank, a sedimentation tank and an advanced treatment tank (optional), and guarantees that effluent water stably reaches the first-level A standard of Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB18918-2002). Specifically, the anaerobic tank is composed of sectional anaerobicbaffle plates, the aerobic tank adopts a microporous aeration and three-dimensional soft filler device, a rotary drum filter is arranged in the sedimentation tank, and a membrane bioreactor and a disinfection treatment apparatus can be optionally equipped in the advanced treatment tank according to treatment requirements. The overground unit mainly comprises a vegetation area and a control system, wherein plants are fixed by a support net, the root systems extend into the anaerobic tank and aerobic tank, and the control system is located above the sedimentation tank. The integrated sewage treatment equipment provided by the invention is low in energy consumption, flexible in combination and stable in performance, and has the functions of environment beautifying, education and publicity and the like.

Description

technical field [0001] The invention belongs to the technical field of wastewater biological treatment, and in particular relates to a landscape-type combined sewage treatment equipment and a method for using the same. Background technique [0002] With the development of the economy and the improvement of living standards, the increase in rural domestic water has led to an increase in sewage discharge; coupled with the characteristics of numerous pollution sources, dispersion, and large impact loads in rural sewage, most rural sewage has been degraded. Less than effective processing. Large-scale sewage treatment plants in cities are limited by the characteristics of rural sewage and the lag of sewage pipe network construction, so it is difficult to conduct centralized treatment of rural sewage. At the same time, the country puts forward higher requirements on the discharge standards of sewage treatment. [0003] Although the existing sewage treatment equipment can effecti...

AI Technical Summary

Problems solved by technology

[0003] Although the existing sewage treatment equipment can effectively treat rural sewage and meet the first-class B discharge standard, it still has disadvantages such as poor load impact resistance, high energy consumption, high manual maintenance costs, strong odor, and low degree of automation. It does not have a high room for standard improvement and renovation, and cannot meet the country's growing water quality requirements and the improvement of people's quality of life
