Problems solved by technology

[0002] The process of sand making needs to consume a lot of water resources and generate a lot of sewage. However, the traditional sewage treatment method has a low recovery rate and causes a lot of waste of water resources. In areas where water resources are scarce, it is easy to affect the normal production of sand and gravel.
In addition, the sewage generated during the sand making process will contain suspended solids and mineral pollution, and cannot be discharged directly, otherwise it will pollute the environment and cause siltation in the river

Embodiment Construction

[0031] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0032] like figure 1 As shown, the present invention provides a sewage treatment system for treating sewage generated in the sand making process. By implementing mud-water separation, the problem of sewage recycling is solved, and low pollution and low discharge of sewage are realized. The sewage treatment system includes a dense tower split tank 1, a thick tower 2, a filter press 3, a medicament mixer 4 and a sedimentation tank 5. The dense tower split tank 1 is used to divide the sewage, and the thick tower split tank The water outlet...

Abstract

The invention relates to the technical field of sewage treatment, in particular to a sewage treatment system and method, which are used for treating sewage generated in the sand making process. The sewage treatment system comprises a dense tower diversion channel, a dense tower, a sedimentation tank, a medicament stirrer and a filter press, wherein the dense tower diversion channel is applied to sewage diversion treatment; the water outlet of the dense tower diversion channel is connected with the water inlet of the dense tower; the bottom water outlet of the dense tower is connected with thewater inlet of the filter press through a pipeline; the top water outlet of the filter press and the top water outlet of the dense tower are connected with the water inlet of the sedimentation tank; the water outlet of the sedimentation tank is connected with the water inlet of the medicament stirrer; the water outlet of the medicament stirrer is connected with the water inlet of the dense tower diversion channel. By adopting the sewage treatment system and method, recycling of the sewage generated in the sand making process is realized, and low pollution and low discharge of the sewage are achieved to save water resources; moreover, the problems of environmental pollution and river siltation caused by direct discharge of the sewage can also be solved.

Description

【Technical field】 [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage treatment system and method. 【Background technique】 [0002] The process of sand making needs to consume a lot of water resources and generate a lot of sewage. However, the traditional sewage treatment method has a low recovery rate and causes a lot of waste of water resources. In areas where water resources are scarce, it is easy to affect the normal production of sand and gravel. In addition, the sewage generated during the sand making process will contain suspended solids and mineral pollution, and cannot be discharged directly, otherwise it will pollute the environment and cause siltation in the river. 【Content of invention】 [0003] The purpose of the present invention is to provide a sewage treatment system to recycle and recycle the sewage generated in the sand making process, basically realize zero discharge of sewage, thereby saving water resources;...
