Abstract

The embodiment of the invention discloses a treatment system and method for deodorizing manure water in a farm, and aims to solve the problems that the manure water returning efficiency is low and the production efficiency of the farm is influenced due to the odor phenomenon of the manure water in the manure water returning process. The treatment system comprises a solid-liquid separation device, an anaerobic pond, an aeration pond, an aeration device and a control device. A liquid outlet of the solid-liquid separation device is connected with the anaerobic pond, and the anaerobic pond is connected with the aeration pond; the control device is electrically connected with the aeration device; the liquid dung treated by the solid-liquid separation device flows into the anaerobic pond and overflows to the aeration pond; the control device is used for controlling the aeration device to perform intermittent aeration treatment on the liquid dung in the aeration pond. Wherein the aeration quantity of the aeration device is 26 m < 3 >/min to 30 m < 3 >/min, and the aeration period is 6 h to 8 h.

Description

technical field [0001] The embodiments of the present invention relate to the field of sewage treatment, and in particular to a treatment system and method for deodorizing manure in farms. Background technique [0002] With the large-scale development of the aquaculture industry, the ensuing "stinky" phenomenon of manure water has become a key factor affecting the return of manure water to the field. [0003] At present, large-scale farms usually adopt the two-stage anaerobic pond manure treatment process, and the manure is returned to the field after being fermented in the two-stage anaerobic pond. However, the concentration of organic matter in dung water is relatively high. During anaerobic fermentation, due to the growth and metabolism of anaerobic bacteria, a large amount of malodorous gas will be produced. This makes these malodorous gases spread further, resulting in odor pollution of the surrounding environment. Farmers have great resistance and low acceptance, resu...
