Embodiment Construction

[0033] Attached to the following Figure 1-4 This application will be described in further detail.

[0034] The embodiment of the present application discloses a municipal sewage treatment device. refer to figure 1 , the sewage treatment device includes a sedimentation tank 1, a clarification tank 2 and a collection tank 3 that are connected to each other in sequence. Municipal sewage can enter the sedimentation tank 1 for preliminary precipitation. The upper layer of the sewage after sedimentation is relatively clean, and the lower layer is the sludge after sedimentation. The sedimentation tank 1 is connected with a drainage pipe 4, and the clarification tank 2 is provided with a filter cartridge 5. The sewage above the sedimentation tank 1 enters the filter cartridge 5 through the drain pipe 4, and the sewage filtered by the filter cartridge 5 then enters the collection tank 3. After the filter cartridge 5, the turbidity of the water can be reduced, and the sewage treatmen...

Abstract

The present application relates to the field of sewage treatment technology, in particular to a municipal sewage treatment device, which includes a sedimentation tank, a clarification tank and a collection tank that are connected to each other in sequence, a drainage pipe is connected to the sedimentation tank, a filter cartridge is arranged in the clarification tank, and the upper end of the filter cartridge The water outlet of the drainage pipe is connected with the opening of the upper end of the filter cartridge; the filter cartridge includes a fixed installation plate, a first filter screen connected with the fixed installation plate, and a second filter screen sleeved on the outside of the first filter screen. . In the present application, after the sewage in the sedimentation tank has undergone preliminary precipitation, the drain pipe can discharge the relatively clean water in the upper part into the filter cartridge, so that the water entering the clarification tank is cleaner and the phenomenon of turbidity of the sewage entering the clarification tank is reduced. Even if the loss of floating sludge is inevitable in the sedimentation tank, the filter cartridge can filter the floating sludge, so as to ensure the effect of filtering and sedimentation.

Description

technical field [0001] The present application relates to the field of sewage treatment technology, in particular to a municipal sewage treatment device. Background technique [0002] Sewage treatment refers to the process of purifying sewage so that it can meet the water quality requirements of a certain water body for drainage or reuse. In daily municipal work, a large amount of sewage will be generated, which needs to be treated. The general sewage treatment is to add sewage treatment agent to the sewage tank to make it undergo chemical reaction and purify the harmful substances in the sewage, so that the sewage can be treated. Emission Standards. [0003] my country's urban sewage treatment standards are divided into three levels, namely primary treatment, secondary treatment and tertiary treatment. Primary treatment is the removal of suspended solids in sewage by physical methods such as sedimentation, flotation, and filtration, or by chemical methods such as coagulat...
