Sewage discharge and treatment equipment for cities

Abstract

The invention provides sewage discharge and treatment equipment for cities. The sewage discharge and treatment equipment comprise a sewage collecting tank, a primary residue filter screen, a protruding filter screen, a water inlet pipe, an arc-shaped water baffle, a sundries pressing block box structure, a gravel filtering through pipe structure, an oblique water guide pipe, a sewage precipitate filter box structure, a first water guide pipe, a sewage sterilizing and purifying box structure, a second water guide plate, a sewage detection box, a water quality detector, a sewage circulating discharge guide pipe structure, a protective shell and a controller, wherein the primary residue filter screen is transversely embedded into the upper portion of the inner side of the sewage collecting tank. The sewage discharge and treatment equipment has the advantages that by the protruding filter screen, floating objects in the sewage can be conveniently separated from the sewage, and the floatingobjects can be prevented from attaching to the primary residue filter screen so as to prevent the normal use of the primary residue filter screen from being affected; by a longitudinal separation screen, a gravel layer and a quick lime layer, the gravel layer can be separated from the quick lime layer, and the gravel layer and the quick lime layer can improve the removing and filtering effects onmicro-particle sundries in the sewage.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, in particular to an urban sewage discharge treatment equipment. Background technique [0002] Urban sewage treatment has always been a difficult problem in environmental protection, and environmental protection is a basic national policy of our country. The environmental protection industry is one of the new economic growth points of the national economy. The state encourages and supports environmental protection projects. At present, it is necessary to build storage and lifting equipment in places where sewage and wastewater can not be self-discharged. Most of the traditional sewage and wastewater storage and lifting equipment are made of reinforced concrete. In this way, not only the construction period is long and the construction is difficult, but also it is easy to leak, block, difficult to clean, etc., and will pollute the environment. Although there are various forms of sewage tr...

Problems solved by technology

[0006] In order to solve the above-mentioned technical problems, the present invention provides a kind of urban sewage discharge treatment equipment to solve the problem that the existing sewage discharge treatment equipment is inconvenient to isolate the floating objects in the sewage, the filtering effect on the particulate impurities in the sewage is poor, and the pollution of the sewage is poor. The sedimentation effect is poor, it is inconvenient to kill the bacteria in the sewage, it is not able to detect the water quality of the treated sewage, it is inconvenient to circulate the sewage that does not meet the standard and it is inconvenient to extract the sewage from the outside to the inside
