Small town sewage treatment and recycling equipment

Abstract

The invention discloses small town sewage treatment and recycling equipment which structurally comprises a treatment device, a water inlet pipe, a dosing box and a drainage pipe, the water inlet pipe is embedded in the top of the left side of the treatment device and communicates with the treatment device, and the dosing box is fixedly installed at the upper left end of the treatment device. Heat is transmitted to a needle point along the conduction of a rotating rod, and the effect of melting ice and snow at the top of the rotating rod is improved through the needle tip, so that part of ice and snow contained in sewage are prevented from blocking the interior of the drainage pipe, normal circulation of the sewage in the drainage pipe is ensured, the sewage discharge amount is prevented from being reduced, low-temperature sewage is prevented from directly entering a biological tank, and microorganism death in the biological tank is prevented. Sewage flows onto a sinking plate and is separated by division bars, so that the impact force of the sewage is weakened, meanwhile, the weight of the sewage drives the sinking plate to sink downwards, the impact force of the sewage on microorganisms is reduced, normal growth of the microorganisms in the biological tank is ensured, and the treatment effect of the microorganisms on the sewage is improved.

Description

technical field [0001] The invention relates to the technical field of urban sewage treatment and resource utilization, and more specifically, relates to a small-scale urban sewage treatment and recycling equipment. Background technique [0002] Urban sewage refers to domestic sewage, industrial wastewater and runoff sewage in urban areas. Urban runoff sewage is formed by rain and snow washing urban air pollutants and washing buildings, ground, waste residue and garbage. It needs to be used for sewage treatment and reuse The equipment processes and recycles it, and the microorganisms inside the equipment are reused after sewage treatment to reduce pollutants in the water. However, in winter, there are more ice and snow in the urban runoff sewage, and when the sewage is discharged into the treatment and reuse equipment, Ice and snow are easy to block inside the water inlet pipe, thereby reducing the amount of sewage discharged, and the temperature of the sewage containing ice...

[0002] Urban sewage refers to domestic sewage, industrial wastewater and runoff sewage in urban areas. Urban runoff sewage is formed by rain and snow washing urban air pollutants and washing buildings, ground, waste residue and garbage. It needs to be used for sewage treatment and reuse The equipment processes and recycles it, and the microorganisms inside the equipment are reused after sewage treatment to reduce pollutants in the water. However, in winter, there are more ice and snow in the urban runoff sewage, and when the sewage is discharged into the treatment and reuse equipment, Ice and snow are easy to block inside the water inlet pipe, thereby reducing the amount of sewage discharged, and the temperature of the sewage containing ice and snow is relatively low. After the untreated low-temperature sewage is discharged into the water body, the water temperature of the receiving water body will drop, which will endanger the treatment process. The growth of microorganisms inside the equipment can even lead to death, thereby reducing the treatment effect of microorganisms on urban sewage
