Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a flocculation and clarification sewage treatment device used for sewage treatment. Background Art

[0002] Flocculation clarification is an important technology in water treatment. Flocculation refers to the process of forming larger flocs by adding flocculants and other means to fine particles or colloidal substances suspended in water, so as to facilitate subsequent separation and removal. During the flocculation clarification process, flocculants interact with impurity particles in the water, and through charge neutralization, adsorption bridging and other mechanisms, particles are caused to gather together to form flocs. These flocs are usually much larger than the original particles and can be more effectively precipitated or separated from the water by other means. Common flocculants include inorganic flocculants and organic flocculants.

[0003] At present, in the process of flocculation and clarification of sewage, a large amount of sludge will be produced when flocculants mix with impurity particles in sewage, and the existing flocculation and clarification sewage treatment equipment is unable to treat the sludge. The increase of sludge will simultaneously lead to an increase in the operating cost of the sewage treatment plant, and then lead to an increase in the treatment cost of sewage. In the process of flocculation and sedimentation of sewage, the sewage and flocs are usually separated by filtering through filter plates. However, with the conventional setting of filter plates, flocs are easily accumulated on the surface of the filter plates, which causes the filter plates to be blocked, thereby affecting the filtration efficiency and causing certain inconveniences in use.

At the same time, during the adding process, the second motor 51 drives the anti-settling rod 52 to rotate, stirs the biological settling aid, and prevents the biological settling aid from settling.

[0028] Example 3

[0029] like Figure 1-4 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the flocculation and stirring component 3 includes a first motor 31, the surface of the first motor 31 is fixedly connected to the top of the bin cover 22, the surface of the first motor 31 shaft is fixedly connected with a stirring rod 32, the surface of the stirring rod 32 is fixedly connected with a stirring blade 33, the structure of the flocculation and stirring component 3 is the same as the sludge reduction bacteria mixing component 6, the biological settling agent adding component 4 includes a storage bin 41, the bottom of the storage bin 41 is fixedly connected to the top of the bin cover 22, one side of the inner cavity of the storage bin 41 is fixedly connected with a feeding pipe 42, one end of the feeding pipe 42 is fixedly connected to the bottom of the bin cover 22, and the middle part of the feeding pipe 42 is fixedly connected with a feeding pump 43, the structure of the biological settling agent adding component 4 is the same as the structure of the sludge reduction bacteria adding component 7, and the anti-sedimentation component 5 includes a second motor 51, and the bottom of the rotating shaft of the second motor 51 is fixedly connected with an anti-sedimentation rod 52.

During the adding process, the first motor 31 drives the stirring rod 32 and the stirring blade 33 to rotate, and mixes the sewage and the flocculant evenly. Then, after a short sedimentation and clarification, the water outlet pipe 27 is opened to allow the sewage to be filtered through the inclined filter plate 26 and then discharged. Then, under the action of the sludge pump 29, the sludge settled to the bottom of the inner cavity of the flocculation sedimentation chamber 23 is discharged along the sludge pipe 28 enters the sludge treatment chamber 24, and under the action of the sludge reduction bacteria adding component 7, sludge reduction bacteria are added into the sludge treatment chamber 24, and then under the action of the sludge reduction bacteria mixing component 6, the sludge reduction bacteria and the sludge are evenly mixed. At the same time, under the action of the spiral blade 8, the sludge at the bottom of the inner cavity of the sludge treatment chamber 24 is transported upward along the conveying cylinder 211 to achieve a better mixing effect. Under the action of the sludge reduction bacteria, the organic matter in the sludge is decomposed and converted into carbon dioxide, thereby reducing the amount of sludge and reducing the cost of sewage treatment. After the treatment is completed, the sludge reduction bacteria mixing component 6 is rotated in the opposite direction, which can make the spiral blade 8 rotate in the opposite direction to push the sludge toward the sewage outlet pipe 212, thereby accelerating the discharge speed of the sludge and making it more convenient to use.

[0033] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention.
