Micro-system for deep purification of domestic sewage

Abstract

The invention discloses a micro-system for deep purification of domestic sewage comprising a pre-settling tank, a contacting tank, an aeration tank, a water dividing system and an anaerobic treatment tank, wherein the pre-settling tank is provided with two segregation barriers, the contacting tank is filled with formed contacting filtering material CAP, the aeration tank is provided with a water level control pump, the water dividing system comprises a bypass channel and a water distribution pipeline.

Description

technical field

[0001] The invention relates to a domestic sewage purification system, in particular to a miniature domestic sewage deep purification system. Background technique

[0002] The miniature domestic sewage treatment system has broad application and development prospects due to its advantages of simple installation, broad-spectrum adaptation, and no need for sewage pipelines. However, the system design currently used in the domestic market has the following main problems:

[0003] 1. Most of the designs are designed and manufactured for domestic sewage to meet the discharge standards, while my country's requirements for domestic sewage to meet the discharge standards are still relatively low, and most areas do not limit the content of phosphorus and nitrogen, so the effluent of most systems cannot be To meet the requirements of wastewater recycling, these designs are already facing the situation of elimination in today's increasingly scarce water resources.

Examples

Embodiment Construction

[0023] This embodiment is designed based on the research and operation results of similar systems at home and abroad, combined with indoor simulation and actual pilot test. In general, in the design of this embodiment, the problems and contradictions existing in the prior art are effectively solved and avoided.

[0024] Referring to Figure 1, Figure 2 and image 3 , which are the system flow chart of the deep purification system for miniature domestic sewage according to the present invention; the vertical cross-sectional structural schematic diagram of the pre-sedimentation tank, the contact tank, the aeration tank, and the vertical cross-sectional structural schematic diagram of the anaerobic tank. The main processing procedures and functions are described as follows:

[0025] 1. Pre-sedimentation tank 1

[0026] The sewage automatically flows into the system through the sewage pipeline, and first enters the pre-sedimentation tank 1, with a size of 1×1×2.5m 3 , A sliding m...
