Embodiment Construction

[0034] In order to better understand the present invention, the content of the present invention will be further clarified below in conjunction with the embodiments to reflect the functions of the present invention. However, the content of the present invention is not limited only to the following examples.

[0035]This example involves a kind of sewage treatment equipment, which is a box-type equipment with a rectangular box body. The material of the box body is carbon steel sprayed plastic, the thickness is 1.6mm, and the size is 2.7m×1.5m×2.0m. The inside of the box body is along the water flow. There are air flotation box 1, volcanic rock stuffing box 2, biological filter material stuffing box 3, anthracite stuffing box 4 and clean water tank 5 in the direction. The side of air flotation box 1 is provided with water inlet 6 connected to the water inlet pipe, and the clean water tank 5 is on the same side. A water outlet 7 is provided at the bottom, and a dissolved air pump...

Abstract

The invention discloses sewage treatment equipment which is box-type equipment; an air floatation box (1), a volcanic rock filler box (2), a biological filter material filler box (3), an anthracite filler box (4) and a clear water box (5) are arranged in a box body in the water flow direction, and a water inlet (6) is formed in one side of the air floatation box (1) and connected with a water inlet pipe; a water outlet (7) is arranged on the bottom, on the same side of the water inlet, of the clear water box (5), and a dissolved air pump (8) is arranged on one side of the air floatation box (1); a bubble dispersing disc and the clear water box (5) are respectively connected to the bottom of the air floatation box (1); a backwashing water inlet area (9) is arranged on one side, opposite tothe water inlet (6), of the box body; and a backwashing water inlet pipe (10) is arranged at the bottom of the backwashing water inlet area (9). The equipment disclosed by the invention can be mountedon a bank close to a sewage outlet, treats domestic and industrial sewage discharged from a sewage outlet by utilizing the combination of air floatation and multiple filtering fillers, has the effects of removing suspended matters, degrading ammonia nitrogen, phosphorus and organic matters and the like, improves the water quality and then discharges the sewage into a river channel.

Description

technical field [0001] The invention relates to sewage treatment equipment, in particular to sewage treatment equipment and a method for small flow, and belongs to the technical field of multiple sewage treatment. Background technique [0002] In recent years, due to the expansion of urban scale and the development of industrial economy, there are more and more sewage outlets in rivers, and the amount of sewage discharged exceeds the natural purification capacity of rivers, which makes the water quality of rivers in many cities and towns deteriorate, black and odorous water and eutrophication problems seriously affect people's lives Health and city beauty. [0003] River and lake water treatment projects should be premised on source control and sewage interception, but the actual situation is often difficult to discharge sewage after centralized treatment due to problems such as geographical restrictions, aging pipe networks, and insufficient funds, especially in rural areas...
