Embodiment 1

[0046] Such as Figure 1-14As shown, a decentralized domestic sewage purification system includes a grid well 1, a HUSB tank 4, a SBAR purification tank 5 and a sludge tank 3 arranged in sequence along the water flow direction, and a stainless steel bracket 501 is installed in the HUSB tank 4. The water inlet stirring assembly 401 and the water inlet pumping assembly 402, the water inlet stirring assembly 401 includes an air intake pipe, the lower end of the air intake pipe is provided with a horizontally installed air intake branch pipe, and a number of exhaust holes are provided on the air intake branch pipe. During specific implementation, Start the aeration pump to blow air to achieve stirring. The water inlet and pumping assembly 402 includes a water inlet pipe 4021, and the water inlet pipe 4021 is provided with a water inlet liquid seal 5020, an air inlet 4023, a water inlet 4022 and a water outlet 4024. The water outlet is connected to the SBAR purification tank 5 thro...

Embodiment 2

[0055] This embodiment is a further optimization made on the basis of Embodiment 1. Specifically, a well shaft 7 is socketed on the tank mouth of the HUSB tank 4 and the SBAR purification tank 5, and a well cover 8 is movably connected to the well shaft 7, and a well cover 8 is provided. There is a safety lock, and this setting enables the tank body to be designed with different heights of the shaft 7 according to the needs, which is flexible in processing, reliable and safe.

Embodiment 3

[0057] This embodiment is a further optimization made on the basis of Embodiment 2. Specifically, a liquid level sensor is installed inside the HUSB tank 4 and the SBAR purification tank 5, and the liquid level sensor is connected with the electrical signal of the controller to realize Automatically judge the water level.

Abstract

The invention discloses a distributed domestic sewage purification system. The system comprises a grid well, an HUSB tank, an SBAR purification tank and a sludge tank which are sequentially arranged in the water flow direction; a water inlet stirring assembly and a water inlet water lifting assembly are arranged in the HUSB tank through stainless steel supports; a water discharge water lifting assembly and a backflow water lifting assembly are arranged in the SBAR purification tank through stainless steel supports; aeration assemblies are respectively arranged in the HUSB tank and the SBAR purification tank; each aeration assembly comprises a plurality of aeration discs which are connected through gas path pipelines; the system further comprises an automatic control cabinet; and an electric control system and an aeration pump are arranged in the automatic control cabinet, wherein the electric control system comprises a controller which is electrically connected with the aeration pump.The distributed domestic sewage purification system is high in automation degree and good in water outlet effect, and can reach the grade-I B standard of "Discharge standard of pollutants for municipal wastewater treatment plant" (GB18918-2002).

Description

technical field [0001] The invention relates to the field of sewage treatment equipment, in particular to a decentralized domestic sewage purification system. Background technique [0002] Domestic sewage is the wastewater discharged by residents in their daily life, mainly from residential buildings and public buildings, such as residences, institutions, comprehensive office buildings, schools, hospitals, shops, public places, new rural construction and industrial enterprise toilets, etc. The pollutants contained in domestic sewage are mainly organic matter (such as protein, carbohydrates, fat, urea, ammonia nitrogen, etc.) and a large number of pathogenic microorganisms (such as parasite eggs and intestinal infectious viruses, etc.). The organic matter present in domestic sewage is extremely unstable and easily rots to produce stench. Bacteria and pathogens reproduce in large numbers using organic matter in domestic sewage as nutrients, which can lead to the spread of inf...
