Embodiment 1

[0033] A kind of method of campus sewage treatment of the present invention, specific implementation process is as follows,

[0034] Mix the experimental sewage and potassium aluminum dodecyl sulfate evenly according to the mass ratio of 100000:1, and then stir for 1 hour; use a 2-layer grease trap to separate the sewage from the restaurant, and the mesh diameter of the grease trap is 0.1 mm; The pH of domestic sewage was detected to be 6.3, so calcium oxide was added to adjust the pH of domestic sewage to 6.5. The above-mentioned 3 kinds of treated sewage are mixed together to obtain treated water a;

[0035] Use two layers of filter screens to carry out grid treatment on the treated water a. The mesh diameter of the first layer of filter screens is 7cm, the mesh diameter of the second layer of filter screens is 2cm, and the distance between the filter screens is 5m. Remove the garbage and larger impurities in the treated water a to obtain the treated water b;

Embodiment 2

[0041] A kind of method of campus sewage treatment of the present invention, specific implementation process is as follows,

[0042] Mix the experimental sewage and potassium aluminum dodecyl sulfate uniformly according to the mass ratio of 100000:1.5, and then stir for 3 hours; use a 5-layer oil-separating net to conduct oil-separating treatment on the restaurant sewage. The mesh diameter of the oil-separating net is 2mm ; It is detected that the pH of the domestic sewage is 6.0, and the pH of the domestic sewage is adjusted to 7.1 by adding waste sulfuric acid or waste hydrochloric acid. The above-mentioned 3 kinds of treated sewage are mixed together to obtain treated water a;

[0043] Use 4 layers of filter screens to carry out grid treatment on the treated water a. The mesh diameter of the first layer of filter screen is 10cm, the mesh diameter of the second layer of filter screen is 7cm, and the mesh diameter of the third layer of filter screen is 3cm. The mesh diameter o...

Embodiment 3

[0049] A kind of method of campus sewage treatment of the present invention, specific implementation process is as follows,

[0050] Mix the experimental sewage and potassium aluminum dodecyl sulfate evenly according to the mass ratio of 100000:1.3, and then stir for 2 hours; use a 3-layer oil-separating net to separate the sewage from the restaurant, and the mesh diameter of the oil-separating net is 1mm Detecting that the pH of the domestic sewage is 6.8, the above three treated sewage are directly mixed together to obtain treated water a;

[0051] Use 3 layers of filter screens to perform grid treatment on the treated water a. The mesh diameter of the first filter screen is 10cm, the mesh diameter of the second filter screen is 5cm, and the mesh diameter of the third filter screen is 1cm. The distance between the filters is 5m, and the garbage and larger impurities in the treated water a are removed to obtain the treated water b;

Abstract

The invention provides a schoolyard sewage treatment method and a schoolyard sewage treatment device. The treatment method comprises the following steps: performing flocculation treatment, oil removal treatment and neutralization treatment on schoolyard sewage, performing grid treatment, anaerobic reaction, aerobic reaction and sedimentation treatment, collecting surface precipitation water, performing grid treatment and sedimentation treatment on the surface precipitation water, and collecting the schoolyard sewage and surface precipitation water subjected to sedimentation treatment to serve as urban miscellaneous water. The device comprises a flocculation basin, an oil removal pool and a neutralization pond which are connected with a grid section a by virtue of pipelines, as well as a regulating valve, an anaerobic tank, an aerobic pool, a settling pond and a treated water collection pool which are sequentially arranged behind the grid section a along the sewage inflowing direction. According to the method and device provided by the invention, recycling of the schoolyard sewage and reutilization of the surface precipitation water are realized, and the problems such as water pollution and deficiency of water resources are solved.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a method for treating campus sewage, and also relates to a device for treating campus sewage. Background technique [0002] At present, colleges and universities use a lot of water due to their relatively concentrated personnel and relatively small numbers of people, mainly including students' domestic water, canteen water, teaching staff's domestic water and experimental water. Therefore, the types of sewage produced are different. The experimental sewage contains chemical substances, heavy metal ions and other harmful substances, and direct discharge will pollute the water body; the canteen water is rich in various organic substances, and direct discharge will lead to eutrophication of the water body, which will also cause environmental pollution. Pollution; while students' domestic water and teaching staff's domestic water contain more N, P detergent compo...
