Pump-free integrated wastewater deep treatment equipment

Abstract

The invention provides pump-free integrated wastewater deep treatment equipment, in order to solve the problems that current wastewater treatment equipment is large in occupied area, heavy in the energy consumption and the like. The equipment belongs to the technical field of wastewater treatment equipment, and comprises an adjusting tank, an anoxic tank, aerobic tanks, a secondary sedimentation tank, a sand filter and a clean water tank, wherein the sand filter is arranged in the secondary sedimentation tank, the adjusting tank is communicated with the anoxic tank through an adjusting tank stripping tube, the anoxic tank is communicated with the adjacent aerobic tank through an anoxic tank water passing hole in the bottom of an adjacent baffle plate of the anoxic tank and the adjacent aerobic tank, the third aerobic tank is communicated with the secondary sedimentation tank through a secondary sedimentation tank water passing hole in an adjacent baffle plate of the third aerobic tank and the secondary sedimentation tank, the secondary sedimentation tank is communicated with the sand filter through a sand filtration diversion trench, the sand filter is communicated with the clean water tank through a clean water tube, and the clean water tank is internally provided with a clean water tank stripping tube. According to the equipment provided by the invention, a plurality of wastewater treatment tanks are developed and designed into a whole, so that the occupied area is small, and the land source is saved, a gas stripping manner is adopted to replace a pump to provide power cycle, so that the energy consumption is greatly reduced, and through multilevel oxidation treatment, the wastewater treatment effect is increased.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment equipment, and in particular relates to a pumpless advanced sewage treatment integrated equipment integrating a plurality of sewage treatment pools with different functions. Background technique [0002] Sewage treatment is an important part of environmental protection and environmental pollution control. In the prior art, sewage treatment is carried out step by step, and the treatment equipment is various and huge. According to the different functions of each sewage treatment equipment, it generally includes sewage treatment equipment such as regulating tank, anoxic pond, aerobic pond, secondary sedimentation pond, sand filter, clear water pond, etc. Among them, the regulating pond, anoxic pond and aerobic pond are all equipped with The aeration pipeline aerates the tank, the sand filter is equipped with a sand washing and air lift tube to circulate and clean the filtered quartz sand, an...

AI Technical Summary

Problems solved by technology

The above-mentioned sewage treatment equipment in the prior art is scattered, and each equipment is independent, resulting in a large area occupied by the sewage treatment system, especially in cities and towns where land resources are relatively tight, it is difficult to popularize and apply, which is not conducive to on-site treatment of sewage; Sewage treatment equipment needs water pumps to circulate water, which requires a lot of energy consumption and high operating costs, which is not conducive to energy saving and consumption reduction; each sewage treatment equipment is scattered and requires multiple fans to supply air, resulting in complex air supply pipelines and high energy consumption; In addition, the existing sewage treatment equipment needs special personnel to be on duty for maintenance, and the maintenance cost is high

The above reasons lead to increased difficulty in sewage treatment, which is not conducive to environmental protection
