Problems solved by technology

[0013] However, the above-mentioned prior art has not reported that in the comprehensive utilization of yeast high-concentration organic wastewater, it is prepared into fertilizers and feed additives at the same time through evaporation, concentration, separation and desalination, so as to further reduce the cost of wastewater treatment and achieve resource utilization. The best comprehensive utilization; in addition, there is no report on what means to increase the potassium content in the fertilizer, so as to obtain high-grade potash fertilizer

Embodiment 1

[0066] Embodiment 1 yeast high-concentration organic wastewater treatment process

[0067] according to figure 2 The illustrated process flow for treating high-concentration yeast organic wastewater is for treating high-concentration yeast organic wastewater.

[0068] Specifically, beet molasses was used as raw material to ferment Saccharomyces cerevisiae, and the high-concentration organic wastewater produced by the yeast during the fermentation and separation process was added to a six-effect falling film evaporator (manufacturer: Yixing Grant), and the high-concentration organic wastewater was evenly distributed through the distribution device. Distributed in each effect heater of the evaporator. Under the action of gravity, vacuum induction and air flow, the material flows from top to bottom in the form of a film. During the movement, it exchanges heat with the steam heated on the outer wall of the heater and evaporates. Gas-liquid separation, the upper layer pumps out the...

Embodiment 2

[0094] Embodiment 2 Another kind of yeast high-concentration organic wastewater treatment process

[0095] according to figure 2 The illustrated process flow for treating high-concentration yeast organic wastewater is for treating high-concentration yeast organic wastewater.

[0096] Specifically, beet molasses was used as raw material to ferment Saccharomyces cerevisiae, and the high-concentration organic wastewater produced by the yeast during the fermentation and separation process was added to a six-effect falling film evaporator (manufacturer: Yixing Grant), and the high-concentration organic wastewater was evenly distributed through the distribution device. Distributed in the heater of the evaporator, the material flows from top to bottom in the form of a film under the action of gravity, vacuum induction and air flow. During the movement, it exchanges heat with the steam heated on the outer wall of the heater and evaporates, and then the gas enters the separation chamb...

Embodiment 3

[0121] Embodiment 3 Contains the preparation of the feed of the feed additive that is made by yeast high-concentration organic wastewater concentrate

[0122] The feed additive of embodiment 1 or 2 gained is directly added in the corresponding full-price compound feed product according to the additive dosage described in following table 5, as adding the feed additive of 1.5% (w / w) in the poultry compound feed, then using The feed mixer was mixed for 10 minutes to ensure that the product was evenly mixed in the feed. The mixed product can be directly fed to poultry animals.

Abstract

The invention provides a high-concentration organic yeast wastewater treatment method, a feed additive obtained by the method and a feed additive-containing feed product. High-concentration organic yeast wastewater can be treated and simultaneously converted into a fertilizer and the feed additive for utilization, so the high-concentration organic yeast wastewater treatment method provided by the invention improves the economic benefits of the yeast wastewater, greatly reduces the treatment cost of the yeast wastewater so as to realize the optimal comprehensive utilization of resources, and in addition, increases the potassium content of the fertilizers so as to obtain high-grade sylvinite fertilizers.

Description

technical field [0001] The invention relates to a method for treating yeast wastewater, in particular to a method for treating yeast high-concentration organic wastewater. The invention also relates to a feed additive obtained by the above method and a feed product containing the feed additive. Background technique [0002] Yeast is currently the only microorganism in the world with an annual output of more than one million tons, and is widely used in brewing, food, traditional Chinese medicine, feed, cosmetics and other fields. The yeast industry has formed an independent industrial system in the world, and the annual output is estimated to be more than 3 million tons. Since 1990, the growth momentum of my country's yeast industry has been strong, with an average annual increase of more than 20%. In 2008, the domestic production of active dry yeast is estimated to have reached 200,000 tons. As an important part of the bioengineering industry, the yeast industry has broad ...
