Embodiment 1

[0024] A sewage treatment system, comprising a pretreatment system 1, a biochemical reaction system 2, a disinfection system 3 and a sludge treatment system 4, and each system is connected in series through a conveying pipeline, the pretreatment system 1 includes a sump 11, a coarse Shan 12, fine grid Shan 13 and sedimentation tank 14, described biochemical reaction system 2 comprises reaction tank 21, hydrolytic acidification tank 22 and contact oxidation tank 23, and described disinfection system 3 comprises filter tank 31, disinfection tank 32 and water storage tank 33 , the sludge treatment system 4 includes a sludge tank 41 and a filter press 42 .

[0025] The sewage from various sewage pipes is concentrated in the sump 11, and the larger suspended garbage and sundries in the sewage are intercepted by the coarse grid 12 and the fine grid 13, and then enter the sedimentation tank 14 to stand still. The supernatant enters the biochemical reaction system 2, while the sludge ...

Embodiment 2

[0027] On the basis of Embodiment 1, a water pump 5 is provided between the devices for transporting sewage between the devices.

Embodiment 3

[0029] On the basis of Example 1, the coarse grid is provided with a plurality of parallel grid bars 6, and the distance between two adjacent grid bars 6 is 12-18 mm, which is used to remove the volume Larger suspended garbage, wood blocks and other sundries ensure that the follow-up devices can work normally.

Abstract

The invention discloses a sewage treatment system, which comprises a pretreatment system, a biochemical reaction system, a disinfection system and a sludge treatment system, which are successively connected in series through delivery pipes. The pretreatment system comprises a water collection tank, a coarse screen, a fine screen and a sedimentation basin. The biochemical reaction system comprisesa reaction tank, a hydrolysis-acidification tank and a catalytic oxidation tank. The disinfection system comprises a filter tank, a disinfection tank and a water storage tank. The sludge treatment system comprises a sludge tank and a filter press. Through the arrangement of the pretreatment system, the biochemical reaction system, the disinfection system and the sludge treatment system, the four systems cooperate with each other, and chemical treatment and physical treatment are both involved, thereby fully purifying the sewage. The treated sewage can be used for watering green area and pavements for recycling. Therefore, water resources are greatly saved, and environmental pollution is reduced.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage treatment system. Background technique [0002] With the continuous development of social economy, the contradiction between environmental pollution and economic development has become increasingly prominent, and water pollution has become a public hazard for sustainable development. Whether it is industrial sewage discharged by various enterprises or people's domestic sewage, it is harmful to the environment. Serious damage has been caused, the sewage purification degree of the existing sewage treatment plant is low, and most of the treated water still cannot meet the standard. Contents of the invention [0003] The object of the present invention is to provide a sewage treatment system for the problems that the sewage purification degree of the existing sewage treatment device is low, and most of the treated water still cannot meet the standard. [0004] Th...
