Embodiment Construction

[0017] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.

[0018] Such as Figure 1 to Figure 3 As shown, the integrated domestic sewage treatment device of the present invention includes a sequentially connected hydrolytic acidification tank 2, a contact oxidation tank 3 and a secondary sedimentation tank 5, and a biological filter 8 is arranged in sequence after the water outlet of the secondary sedimentation tank 5 , the middle tank 7 and the quartz sand filter tank 6, the outlet water of the quartz sand filter tank 6 passes through the disinfection tank 10 and finally is discharged by the water outlet 11, and the fan room 9 is located at the disinfection tank 10 side. Among them, the water inlet of the biofilter 8 (that is, the water outlet of the secondary sedimentation tank 5) is located at the top, the water inlet of the middle pool 7 (that is, the water outlet of the biofilter 8) is locate...

Abstract

The invention discloses an integrated domestic wastewater treatment device. The integrated domestic wastewater treatment device comprises a hydrolysis acidification tank, a contact oxidation tank, a secondary sedimentation tank, a biological filtration tank and a quartz sand filtration tank which are connected in sequence, wherein an intermediate water tank is arranged between the biological filtration tank and the quartz sand filtration tank, and the three tanks are closely adjacent to each other in sequence; the filtering materials in the filtration areas of both the biological filtration tank and the quartz sand filtration tank are located below the filtration tanks, and a reversely cleaning device is arranged above the filtration areas. According to the invention, the tank-type biological filtration tank and the tank-type filter are integrated in previous treatment equipment so as to form integrated treatment equipment, as a result, a water flow naturally flows through each functional area from top to bottom, extra lifting pump is needless, valves and connecting pipelines are not required to be arranged in the biologic filtration tank and the filtration area, the consistency and integrity of the equipment are fully ensured, the filed mounting can be quickly performed, besides, embedding is convenient to perform, the occupied area is decreased, the control manner is simplified, the working energy consumption and noise pollution are lowered, and the formation of modularized and mass standard product is facilitated.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to an integrated domestic sewage treatment device. Background technique [0002] The existing domestic sewage treatment equipment is mainly composed of hydrolytic acidification tank, contact oxidation tank and secondary sedimentation tank in series, which are combined into one box or independently into multiple boxes, and are arranged underground or above ground. The effluent from the secondary settling tank is pumped up and sequentially connected in series to the independent tank-type biological filter and independent tank-type filter for treatment, and finally meets the water quality requirements for reuse or discharge. In the existing equipment, due to the need to set up tank-type filter equipment separately, there are many connecting pipelines and pipe valves, complex control, many tanks, and a large area; and the water from the secondary sedimentation tank need...
