Integrated treatment equipment for agricultural sewage

Abstract

The invention relates to the technical field of sewage treatment, in particular to agricultural sewage integrated treatment equipment which comprises a box body, a supporting frame, a water collecting tank, a reaction tank, a water purifying tank and a stirring mechanism, the supporting frame is fixedly connected to the bottom end of the box body, and the water collecting tank, the reaction tank and the water purifying tank are sequentially arranged on the inner wall of the box body; a secondary baffle plate is fixedly connected to one side, close to the water purification tank, of the top end of the inner wall of the reaction tank; a plurality of groups of stirring mechanisms are arranged in the reaction tank and between the secondary baffle plate and the water collecting tank; according to the sewage treatment device disclosed by the invention, large-particle impurities which are difficult to dissolve in sewage can be filtered through the filtering mechanism, and then the flow speed of water flow is slowed down through the first-stage baffle plate, so that the sewage can be preliminarily precipitated in the water collecting tank, particle impurities in the sewage can be reduced, the subsequent flocculation precipitation effect is improved, and the dosage of a coagulant is reduced; the use cost is reduced.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to integrated treatment equipment for agricultural sewage. Background technique [0002] Agricultural sewage refers to the sewage or liquid substances discharged during the process of crop cultivation, livestock raising, and agricultural product processing, which affect human health and environmental quality; its sources mainly include farmland runoff, sewage from feedlots, and sewage from agricultural product processing; sewage contains various Pathogens, suspended solids, chemical fertilizers, pesticides, insoluble solids, and salt, etc.; agricultural sewage has a large amount and wide impact; agricultural runoff is most prominently polluted by nitrogen and phosphorus. Reducing and intercepting agricultural runoff nitrogen and phosphorus pollution is of great significance to improving water environment quality. [0003] At present, biofilm technology has attracted great a...

AI Technical Summary

Problems solved by technology

[0003] At present, biofilm technology has attracted great attention due to its advantages of good resistance to water quality shock load, easy operation, stable operation performance, and low cost; however, the available organic matter in existing agricultural runoff is relatively low, and due to the scattered living conditions of people, In order to improve the use value of the equipment, it is necessary to transport the equipment to treat sewage in different places; however, most sewage treatment equipment currently adopts conventional biological treatment methods; therefore, there are usually multiple reaction chambers inside the equipment, resulting in The volume of the equipment is too large, and the biological treatment method has a long treatment cycle, which reduces the efficiency of sewage treatment
