Problems solved by technology

[0021] ①Large floor area
[0022] ②The water distribution pipes are easy to freeze during the winter freezing period, which seriously affects the operation of the entire system
[0023] ③ The conventional sewage treatment system cannot meet the surface water quality standards, and another site needs to be selected for the construction of artificial wetlands for advanced treatment
Conventional subsurface flow constructed wetlands directly receive domestic or industrial water sources, which are easy to block, have poor treatment effects, and cannot meet the process requirements

Embodiment Construction

[0051] Accompanying drawing is a kind of specific embodiment of the present invention. This embodiment includes a regulating tank 1, a hydrolytic acidification pond 2, an anoxic pond 3, an aerobic pond 4, and a sedimentation pond 5 in which sewage enters in sequence. The regulating pond 1 is equipped with a grid for removing larger suspended matter in the sewage, and the sewage After regulating tank 1, it is pumped to hydrolytic acidification tank 2 by pump 14. The regulating pond 1 is in the shape of a tower, and the hydrolytic acidification pond 2, the anoxic pond 3, the aerobic pond 4, and the sedimentation pond 5 are located on the top of the regulating pond 1, and the multi-dry layer subsurface flow wetland water treatment system is set on the tower body of the regulating pond 1. The subsurface wetland water treatment system includes a water distribution area, several subsurface wetland water treatment units, and a catchment channel 6. The subsurface wetland water treatme...

Abstract

The invention relates to a sewage treatment process, in particular to an integrated sewage bio-treatment column, comprising a regulating tank, a hydrolytic acidification tank, an anoxic tank, an aerobic tank and a settling tank; sewage enters the tanks in order. The regulating tank is tower shaped. The hydrolytic acidification tank, the anoxic tank, the aerobic tank and the settling tank are located at the top of the regulating tank. A body of the regulating tank is provided with a subsurface wetland water treatment system having multiple dry layers; the subsurface wetland water treatment system comprises a water distribution area, a plurality of subsurface wetland water treatment units, and a water collection channel; each subsurface wetland water treatment unit comprises microorganism immobilized filler, a primary subsurface wetland, an overflow wall and a secondary subsurface wetland. According to the integrated sewage bio-treatment column, a sewage pretreatment system and a subsurface wetland treatment system are effectively combined, and the subsurface wetland water treatment system in multiple tiers, the overflow wall and upper water distribution pipes are in natural contact with the air, aeration is performed, and thus sewage treatment effect is greatly improved.

Description

(1) Technical field [0001] The invention relates to a sewage treatment process, in particular to an integrated sewage ecological treatment tower. (2) Background technology [0002] Modern sewage treatment technology can be divided into primary, secondary and tertiary treatment according to the degree of treatment. [0003] Primary treatment mainly removes suspended solid pollutants in sewage, and most physical treatment methods can only meet the requirements of primary treatment. After primary treatment, BOD can generally be removed by about 30%, which does not meet the discharge standard. Primary treatment belongs to the pretreatment of secondary treatment. [0004] The secondary treatment mainly removes colloidal and dissolved organic pollutants (BOD, COD substances) in the sewage, and the removal rate can reach more than 90%, so that the organic pollutants can meet the discharge standards. [0005] Tertiary treatment, further treatment of refractory organic matter, nit...
