Integrated device for processing domestic sewage in small towns

Abstract

The invention relates to the technical field of sewage treatment equipment, in particular to an integrated device for processing domestic sewage in small towns. The integrated device comprises a grilled channel, an adjusting pond, a hydrolytic acidification pond, a contact oxidization pond, a coagulation pond, an oblique pipe sedimentation pond, a sterilization pond and a flow groove, which are sequentially connected with one another. Large-block impurities in waste water can be removed through the grilled channel, then the waste water is discharged into the adjusting pond and the hydrolytic acidification pond, pollutants in the waste water can be intercepted by a sludge bed of the hydrolytic acidification pond, macromolecular and complicated organic substances are decomposed into low molecular and simple organic substances through absorption, assimilation and decomposition, the sewage enters the contact oxidization pond after being discharged from the hydrolytic acidification pond, the pollutants in the sewage can be assimilated and decomposed under an aerobic condition to finally generate carbon dioxide (CO2) and water (H2O), and finally the domestic sewage can be discharged by reaching the national standard through the coagulation pond, the oblique pipe sedimentation pond, the sterilization pond and the flow groove; and the water quality is stable and can reach the standard, the processing effect is good, the running cost is low, and the adaptability to the variation of the quality and quantity of the sewage is strong.

Description

technical field [0001] The invention relates to the technical field of sewage treatment equipment, in particular to an integrated device for domestic sewage treatment in small towns. Background technique [0002] As the pace of the construction of small and medium-sized cities and towns in my country is significantly accelerated, the discharge of urban sewage is also increasing. my country's urban sewage discharge is increasing rapidly every year, and it is reported that it will spread at an annual rate of 2.4 billion cubic meters. At the same time, my country's corresponding sewage treatment capacity is relatively limited, which is far from being able to adapt to the excessively fast-growing amount of sewage. Many residents' domestic sewage and fecal sewage are directly discharged into the ground or lakes without any treatment measures, causing serious pollution to local water sources and the surrounding environment, and bringing great hidden dangers to people's living env...
