Description

Sewage treatment equipment for sewage draining outlet

Technical Field

The utility model relates to a sewage treatment device, in particular to a sewage treatment device and a method for a sewage drain outlet, belonging to the technical field of multiple sewage treatment.

Background

Although the environmental protection treatment in China is very strong, the discharge of domestic sewage in many places, factories and domestic sewage can not be completely treated, a centralized mixing treatment, simple filtration or even no treatment mode is generally adopted, the contents of sewage pollutants and organic matters in many rivers and sewage outlets are extremely remarkable, but a large amount of manpower and material resources are not needed for inspection and treatment at present, and the difficulty of the current wastewater treatment is achieved.

The infrastructure of small towns and rural areas in China is relatively weak, and the urban sewage treatment plant cannot well meet the sewage discharge problem caused by social progress and increasing living standard of people. The sewage treatment technology is not commonly used, the sewage treatment efficiency is low, and as a result, a large amount of untreated sewage is discharged into rivers, lakes and seas. The sewage is directly discharged to bring a large amount of inorganic pollutants and organic pollutants into the water body, so that the sensory pollution (floating impurities, turbidity, smell, chromaticity and the like), oil pollution (isolating oxygen enrichment of the water body), acid or alkali pollution, heavy metal pollution (directly or indirectly killing aquatic organisms), organic matter pollution, odor of the water body and vegetative pollution of plants cause the algae in the water body to be abnormally proliferated in a large amount, and the utilization value of the water body is reduced and even completely lost. With the rapid increase of population, the rapid development of industry and the acceleration of urbanization, a large amount of sewage is discharged into water, so that the water quality on the surface of the ground is reduced, the effects of drinking, entertainment, irrigation and cultivation are lost, harmful substances in underground water are increased, and the utilization of the underground water is influenced. Therefore, the technical route of point source control and small-scale sewage centralized treatment is needed to be implemented for sewage in small towns and rural areas, and the water resource is protected as far as possible, so that the water pollution is reduced, and the polluted water is purified or regenerated, thereby realizing the long-term aim of sustainable utilization of the water resource.

The research work of the urban sewage treatment technology in China starts from the end of the 20 th century and the 70 th era, and through years of continuous efforts, great achievements are achieved in the aspect of the urban sewage treatment technology, and the achievements are rich. Meanwhile, with the innovation, new foreign process technology is continuously introduced. At present, on the aspect of water pollution treatment technology, novel activated sludge processes such as a traditional activated sludge method, a time delay aeration method and the like, SBR, AB method, UNITANK and oxidation ditch technologies, A/O method, A2/O and other deformation processes are successfully and widely used. The processes commonly adopted by urban sewage treatment plants in China are leading technologies adopted by developed countries such as Europe and America and are proved to be effective water pollution control technologies.

The urban sewage treatment process is also suitable for sewage treatment in small towns and rural areas in principle. However, the adoption of the urban sewage treatment facility has the problems of high investment, high power consumption and high operating cost, and is not suitable for the development status of small towns and rural areas in China; in addition, the buried integrated sewage treatment equipment developed in early domestic causes low treatment efficiency and poor effect due to imperfect treatment process and technology, and cannot meet the increasingly strict effluent quality index of China; in addition, the buried type is complicated in construction and difficult in maintenance, so that the buried type is mostly abandoned.
