Embodiment Construction

[0016] The embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings; it should be noted that the embodiments are illustrative, not restrictive, and cannot limit the protection scope of the present invention.

[0017] A multi-functional combined purification tank, including a tank body 19, on which an inlet pipe 1 and an outlet pipe 16 are installed, and the inside of the tank body is divided into a first-stage purification area 2 and a second-stage purification area in turn by a partition 13 5. The third-stage purification area 12 and the sedimentation tank 14, the three purification areas are anaerobic tanks and aerobic tanks respectively, the number of the anaerobic tanks is 0-3, and the number of aerobic tanks is 1-3, Its quantity is set according to the amount of sewage. The first-stage purification area is usually an anaerobic tank. The water inlet pipe is connected with the first-stage purification area, and th...

Abstract

The invention relates to a multifunctional combined purification tank. The multifunctional combined purification tank is characterized in that a water inlet pipe and a water outlet pipe are installed on a tank body; the interior of the tank body is divided into a first-stage purifying area, a second-stage purifying area, a third-stage purifying area and a precipitation tank in sequence by baffles; an aeration device is installed in each purifying area; a gas stripping device is installed in the third-stage purifying area; filter beds of biological filter materials are plate-type packing filter beds; galling treatment is carried out on the surfaces of the plate-type packing filter beds to form burr structures. The multifunctional combined purification tank is scientific in design, has a reasonable structure and operates reliably. The treatment device is improved according to the treatment status of domestic sewage in rural families, thereby achieving in-situ treatment, increasing the sewage treatment capacity, improving the sewage treatment effects, reducing the treatment cost and simplifying later pipe network building. Therefore, the device is suitable for extensive popularization in rural areas.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a multifunctional combined purification tank. Background technique [0002] Household sewage refers to household sewage, which includes flushing water, kitchen water, bath water, and washing water. The treatment of domestic sewage should be based on the national domestic sewage discharge standards, according to the characteristics of domestic sewage: discontinuity, intermittent pulse, concentrated water in the morning, middle and evening, and flushing water and kitchen water with refractory Solid particles need to be treated directly and meet national discharge standards, so equipment suitable for decentralized treatment of rural domestic sewage requires higher technology than urban sewage treatment. At present, the relatively common sewage treatment devices are affected by their structure, and the sewage treatment effect is not perfect, and there are still defects such...
