Description

A kind of city domestic sewage purifying processing device

Technical field

This utility model is related to a kind of environment friendly purification apparatus, in particular to a kind of city domestic sewage purified treatment Device.

Background technology

With China city constantly develop and living standards of the people raising, the domestic consumption in city is also continuous Increase, the discharge of corresponding sanitary sewage also gradually increases, and these sewage are usually just directly emitted without process, this Sample not only results in the waste of water resource, can also cause the destruction of ecology, and in the prior art, sanitary sewage adopts thing mostly Reason, the chemistry and method of biology is processed, although its can realize water quality reach discharge standard or it is reusable will Ask, but which there is also certain deficiency, such as cleaning residue is inconvenient, and its processing mode wastes time and energy, while also can shadow Treatment effeciency is rung, the suitability and practicality are restricted, it is difficult to meet the demand in market.

Utility model content

For the problem that prior art is present, the utility model proposes a kind of simple structure, process stabilizing, low cost, net Change the strong city domestic sewage purifying processing device of disposal ability.

This utility model solves the technical scheme of above technical problem：A kind of city domestic sewage purified treatment dress is provided Put, including cesspool, preliminary sedimentation tank, the first filtering ponds, anaerobic pond, anoxic pond, Aerobic Pond, second pond, biofilm filtration pond, sterilization Pond and tank, the cesspool outlet connect preliminary sedimentation tank water inlet, and the preliminary sedimentation tank outlet connects the first filtering ponds and enters The mouth of a river, the first filtering ponds outlet connect anaerobic pond water inlet, and the anaerobic pond outlet connects anoxic pond water inlet, institute Anoxic pond outlet connection Aerobic Pond water inlet is stated, the Aerobic Pond outlet connects second pond water inlet, and the second pond goes out The import connection of mouth connection biofilm filtration pond, the biofilm filtration pond outlet connection sterilization pool water inlet, the sterilization pool go out The mouth of a river connects tank water inlet.

The technical scheme that this utility model is further limited as：

Aforesaid cesspool exit is provided with flow controller.

Aforesaid first filtering ponds are activated carbon filtering ponds, and activated carbon filtering ponds are provided with the first filtering ponds.

Aforesaid anaerobic pond is provided with the first agitator, and anoxic pond is provided with the second agitator.

Aforesaid Aerobic Pond is provided with the first backflow branch road and is connected with anaerobic pond, and aforesaid second pond is provided with the second backflow branch road It is connected with anoxic pond.

Ultraviolet sterilization apparatus are provided with aforesaid sterilization pool.

The beneficial effects of the utility model：Each pond of this utility model effectively can reduce in the middle of sewage some are miscellaneous Matter, is provided with activated carbon filter layer in the first filtering ponds, foreign-matter contamination that can effectively in the middle of absorption effluent, goes out in cesspool Mouth is provided with flow controller, controls flow, it is to avoid flow is excessive, affects the effect for filtering, is also prevented from the liquid of the first filtering ponds Position is too high, and in device, anaerobic pond is provided with the first agitator, and anoxic pond is provided with the second agitator, is slowly stirred, it is not necessary to Carbon source is added, the first backflow branch road and the second backflow branch road in reducing cost, and device, is provided with, can effectively by sewage Nitrogen phosphorus remove clean, apparatus for ultraviolet disinfection is provided with sterilization pool, can be by sewage sufficiently sterilised, and biofilm filtration Pond can be by Impurity removal more tiny in sewage so that sewage is more purified thoroughly, the apparatus structure is simple, stable, Detergent power is strong, can reduce environmental pollution, protects the ecological environment in city.

Specific embodiment

Embodiment 1

The present embodiment provides a kind of city domestic sewage purifying processing device, and structure is as shown in figure 1, include cesspool 1, first Heavy pond 2, the first filtering ponds 3, anaerobic pond 4, anoxic pond 5, Aerobic Pond 6, second pond 7, biofilm filtration pond 8, sterilization pool 9 and water storage Pond 10,1 outlet of cesspool connection 2 water inlet of preliminary sedimentation tank, 2 exit of cesspool are provided with flow controller 13, and preliminary sedimentation tank 2 goes out The mouth of a river connects 3 water inlet of the first filtering ponds, and activated carbon filtering ponds 12 are provided with the first filtering ponds 3, and 3 outlet of the first filtering ponds connects 4 water inlet of anaerobic pond is connect, anaerobic pond 4 is provided with the first agitator 14,4 outlet of anaerobic pond connection 5 water inlet of anoxic pond, anoxic pond 5 are provided with the second agitator 15, and 5 outlet of anoxic pond connection 6 water inlet of Aerobic Pond, Aerobic Pond are provided with the first backflow branch road and anaerobism Pond connects, and Aerobic Pond outlet connection second pond water inlet, second pond 7 are provided with the second backflow branch road and are connected with anoxic pond 5, and two sink The 8 import connection of the outlet connection biofilm filtration pond of pond 7, the outlet of biofilm filtration pond 8 connection 9 water inlet of sterilization pool, in sterilization pool 9 It is provided with ultraviolet sterilization apparatus 11,9 outlet of sterilization pool connection 10 water inlet of tank.

When the device is used, cesspool enters preliminary sedimentation tank by outlet, adjusts flow controller, controls flow, enters just Heavy pond is precipitated, and then enters the first filtering ponds, the activated carbon mistake being provided with the first filter by preliminary sedimentation tank outlet Filtering layer is filtered, and the water after filtration sequentially passes through anaerobic pond, anoxic pond and Aerobic Pond, and in Aerobic Pond, a part is back to anaerobism Pond, is partly into second pond, and the water part into second pond is back to anoxic pond, is partly into biofilm filtration pond, Then sterilization pool is being entered, the apparatus for ultraviolet disinfection being provided with sterilization pool carries out disinfection, the water that final purification is processed enters Enter to tank.

In addition to the implementation, this utility model can also have other embodiment, all employing equivalents or equivalent change The technical scheme to be formed is changed, the protection domain of this utility model requirement is all fallen within.
