Embodiment 1

[0030] (1) The preparation method of the bioflocculant is as follows: 5000L of directly collected pig urine is added to the stock solution of EM bacterial agent according to the volume ratio of 2.5%, and then 5% (50g / kg) of molasses (weight ratio) is added, and stirred evenly , put into a cleaned fermenter, the filling volume is 85%, sealed fermentation, the fermentation temperature is 35 ℃, and the fermentation time is 5 days. Exhaust regularly. When the pH of the fermentation broth drops below 5.0, add 0.5% chitosan (weight ratio), and stir evenly. That is, the bioflocculant is obtained.

[0031] (2) The feces collected by the urine foam feces process enters the sewage collection tank through the pipeline, and the biological flocculant is added to the urine foam feces stock solution with a volume of 50000L in the sewage collection tank, and the addition amount is 10% (volume ratio), and the mixer is stirred evenly (700r / min), the standing time is 0.5h, and then the solid-l...

Embodiment 2

[0035] (1) The preparation method of the bioflocculant is as follows: 4000L of directly collected pig urine is added to the stock solution of the EM bacterial agent according to a volume ratio of 5%, and then 10% (100g / kg) of molasses (weight ratio), and stirred evenly , put into a cleaned fermenter, the liquid content is 90%, sealed fermentation, the fermentation temperature is 25 ℃, and the fermentation time is 10 days. Exhaust regularly. When the pH of the fermentation broth drops below 5.0, add 1.0% chitosan (weight ratio), and stir evenly. That is, the bioflocculant is obtained.

[0036] (2) The feces collected by the urine-foaming feces process enters the sewage collection tank through the pipeline, and the biological flocculant is added to the urine-foaming feces stock solution with a volume of 20000L in the sewage collection tank, and the addition amount is 20% (volume ratio). Stir evenly with a mixer (700r / min), let stand for 8 hours, and then use a solid-liquid sep...

Embodiment 3

[0040] (1) The preparation method of biological flocculant is: the pig urine (4500L) that directly collects, adds EM bacterial agent stoste according to the volume ratio of 3.5%, then adds the molasses (weight ratio) of 8% (80g / kg), Stir evenly, put it into a cleaned fermentation tank with a liquid content of 88%, and seal it for fermentation. The fermentation temperature is 30°C and the fermentation time is 7 days. Exhaust regularly. When the pH of the fermentation broth drops below 5.0, add 0.75% chitosan (weight ratio), and stir evenly. That is, the bioflocculant is obtained.

[0041] (2) Enter the feces collected by the urine foam feces process into the sewage collection tank through the pipeline, add bioflocculant in the urine foam feces stock solution (30000L) in the sewage collection tank, the addition is 15% (volume ratio), and stir through the mixer Evenly (700r / min), the standing time is 2h, and then the solid-liquid separation is carried out with a solid-liquid se...

Abstract

The invention discloses a rapid excrement waste treatment method for pig farms, which can be used for raid treatment of excrement produced by fermented excrement technology during pig raising, effectively solves the pollution problem caused by pig excrement waste, and uses pig excrement waste after treatment into various related industries, thereby greatly benefiting framers.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a rapid treatment method for urine-foamed feces and waste liquid from pig farms. Background technique [0002] In recent years, my country's pig production has shown continuous and stable improvement and development in terms of scale and modern management mode. The breeding production process and subsequent manure treatment have always been the key links in the study and research of the animal husbandry industry. However, the collection of manure in the house , transportation outside the house, and pretreatment, which connect the breeding process in the house and the manure treatment in the field, have not received due attention in some farms, so that many farms are managed in the entire chain of manure collection and treatment after they are put into production. It is not smooth, and various environmental pollution problems have emerged. [0003] The process ...
