Embodiment 1

[0032] After introducing the livestock and poultry wastewater into the regulating tank, add the auxiliary agent (including 30% deodorant and 70% microbial regulator) through a liquid injector according to the amount of wastewater, and then proceed to ultrasonic reactor treatment. The ultrasonic frequency is 40kHZ and the ultrasonic intensity is 50W / cm 2 , Ultrasonic time is 20min each time, there are 5min interruptions, and a total of 48h is treated; in this step, the aeration device, such as the aeration pipe connected to the fan and the aeration pipe, can be treated for 1h each time. Aeration is performed intermittently for 20 minutes to prevent the anaerobic odor of the wastewater; the treated wastewater from the regulating tank is passed through the coarse screen to remove the larger solids to obtain the first-level separation. After the separated liquid is introduced into the separation tank, it passes through the liquid injector Add additives (including 30% deodorant, 70% ...

Embodiment 2

[0035] After introducing the livestock and poultry wastewater into the regulating tank, add additives (including 40% deodorant and 60% microbial regulator) through a liquid injector according to the amount of wastewater, and then proceed to ultrasonic reactor treatment. The ultrasonic frequency is 22kHZ and the ultrasonic intensity is 80W / cm 2 , Ultrasonic each time is 30min, there are 5min interruptions, and a total of 48h is treated; in this step, the aeration device, such as the fan and the aeration pipe connected to the fan, can be treated for 45min each time. Aeration is performed for 15 minutes with a frequency interval to prevent the anaerobic odor of the wastewater; the treated wastewater from the regulating tank is passed through a coarse screen to remove larger solids to obtain a first-level separation. After the separated liquid is introduced into the separation tank, it is injected Adding additives (including 40% deodorant and 60% microbial regulator) according to th...

Abstract

The invention relates to a method for harmlessly treating livestock and poultry breeding waste water, comprising the following steps of: after injecting the livestock and poultry breeding waste water into an adjusting tank, adding an addition agent to aerate and stir; simultaneously, carrying out ultrasonic treatment; coarsely screening and separating so as to remove large particles and obtain a first-stage separated substance; injecting the waste water of the adjusting tank into a separation tank; adding the addition agent again to perform aeration, stir and aerobic treatments; injecting in separation equipment for separating to obtain a second-stage separated substance and separated waste water; adsorbing and filtering the separated waste water through an adsorbent so as to obtain recycled or dischargeable standard water; and simultaneously, obtaining a third-stage separated substance. The method disclosed by the invention has the advantages of simple process, easiness in operation and high efficiency. By means of a treatment system for separating solid and liquid and organic substances, contents of organic substances and nutritional components in the livestock and poultry breeding waste water can be reduced effectively; the environment pollution problem of the livestock and poultry breeding waste water is solved; the water quality of the treated livestock and poultry waste water can achieve the discharge standard; the separated substances can be recycled in other fields; and the invention provides an effective approach for harmlessly treating the livestock and poultry breeding waste water and has a realistic significance.

Description

Technical field [0001] The invention belongs to the technical field of wastewater treatment, and specifically is a method for the harmless treatment of livestock and poultry wastewater, and correspondingly, a method for reusing the separated material after wastewater treatment is also proposed. Background technique [0002] As people become familiar with the living conditions and living habits of livestock and poultry animals, and at the same time to meet the needs of different tastes, more and more livestock and poultry animals are gradually being kept in captivity, which greatly meets the needs of people, but also Cause a certain negative impact on our living environment. The waste water caused by the captive breeding of livestock and poultry animals contains a large amount of organic matter, and its pollution load is high. If it is directly discharged or washed into rivers and lakes with rain, it will consume a large amount of dissolved oxygen in the water body and make the wa...
