Problems solved by technology

[0004] The existing aquaculture wastewater treatment process is relatively simple and backward, and the treated aquaculture wastewater cannot stably meet the national wastewater discharge standards, seriously polluting the water body
Or have a certain treatment effect, but the structure is complicated and the operation is cumbersome, such as a kind of intensive pig raising wastewater treatment equipment disclosed in CN 206188598U

Embodiment 1

[0042] Embodiment 1: Integrated livestock and poultry breeding wastewater treatment device, the device is an integrated container structure, including anaerobic zone 2, aerobic zone 3, ozone zone 4, backwash liquid storage zone 5 and equipment operation zone arranged in sequence twenty one. Described anaerobic zone 2 comprises water inlet and water inlet pipe 1, and water inlet is also provided with filter 7, and filter screen adopts mechanical slag removal, places anaerobic zone inside. The top of the anaerobic zone is provided with a stirring motor 8, and the stirring motor drives the agitator 9 to stir, and the bottom is provided with a mud discharge port 15 and a mud discharge pipe 16. The aerobic zone is provided with a membrane module 10, the membrane module is connected to the bottom of the ozone zone 4 and the backwash liquid storage zone 5 through a liquid connection pipe 11, a pressure gauge 13 and a suction pump 12 are installed on the liquid connection pipe, Valve...

Embodiment 2

[0050] like image 3 Shown, identical with the structure of embodiment 1, difference is also to be provided with sewage backflow pipe 23, backflow valve 24 and backflow pump 25 between the ozone zone overflow port and the anaerobic zone. One end of the sewage return pipe is connected to the filter, and the other end is connected to the overflow port of the ozone zone. The sewage return pipe is provided with a valve and a return pump. In order to prevent the effluent after primary treatment from failing to meet the discharge standard, the above-mentioned structure is set up. If the effluent can meet the standard after primary treatment, the wastewater does not need to be refluxed for secondary treatment.

[0051] The device provided by Embodiment 1 and Embodiment 2 of the present invention has a good treatment effect on rural small-scale standardized pig farm wastewater. Taking the processing device in Embodiment 1 as an example, the pig wastewater is treated by a period of two...

Abstract

A livestock and poultry breeding wastewater treatment device and method are disclosed. The device comprises an anaerobic zone, an aerobic zone and an ozone zone which are sequentially arranged, wherein an inlet of the anaerobic zone is connected with a water inlet pipe, the upper portion of the anaerobic zone is connected to the aerobic zone, the upper portion of the aerobic zone is connected to the ozone zone through a pipeline, and an outlet of the ozone zone is connected to a water outlet pipe; an aeration device and a membrane component are arranged in the aerobic zone, and an ozone inputchannel is arranged in the ozone zone. According to the device provided by the invention, an ozone oxidation process is added after anaerobic-aerobic membrane process treatment and tail water after ozone treatment can flow back to the anaerobic zone; through anaerobic ammonia oxidation and short-cut nitrification denitrification, and through ozone, organic pollutants in the wastewater are furtherdegraded, meanwhile, the wastewater decolorization and disinfection effects are improved, and the effluent quality meets the discharge standard of the livestock and poultry industry or zero dischargecan be realized through reclaimed water reuse.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a livestock and poultry breeding wastewater treatment device and method. Background technique [0002] With the continuous development of rural standardization, scale, intensification and industrialized farming, the discharge of livestock and poultry breeding wastewater and domestic sewage has increased significantly. Livestock and poultry breeding wastewater contains a large amount of pollutants with a high pollution load, mainly including organic matter, nitrogen, phosphorus, microorganisms, and toxic and harmful substances. Discharge of high-concentration livestock and poultry breeding wastewater into rivers and lakes will lead to eutrophication of the water body, causing aquatic organisms to gradually die due to lack of oxygen. The organic matter in the water (including the dead bodies of aquatic organisms) decomposes anaerobically, and the water will turn black...
