Problems solved by technology

These wastes contain a large amount of organic matter and mineral elements mainly composed of cellulose, lignin, organic acids, and proteins. The traditional treatment method is anaerobic fermentation to degrade the organic matter, which is not only difficult to meet the national emission standards , fundamentally solve environmental protection problems, and the processed products cannot be effectively used, and can only be used for landfill and discharge treatment, occupying space, deteriorating water quality, and producing secondary pollution
Moreover, the traditional processing method has a long period, large investment in equipment, high operating costs, and heavy burden on the enterprise, which seriously affects the improvement of the economic benefits of the enterprise.

Embodiment Construction

[0015] The effective utilization method of brewing industry waste of the present invention, at first brewing waste residue is processed to produce fertilizer, and its process steps are as follows:

[0016] a. Solid-liquid separation: The brewing waste is introduced into the dehydration equipment for dehydration treatment, and the extracted wastewater is collected into the reservoir. According to the nature of different materials, it can be divided into the following three processing methods:

[0017] (i) dehydration of the brewing waste residues with corn, sorghum and peas as raw materials with a variable-pitch screw press, so that the moisture content of the material is 55-60%;

[0018] (ii) The brewing waste residue with dried potato as raw material first enters the trypan indigo centrifugal dehydrator for dehydration, so that the moisture content of the material is 80-90%, and then enters the belt filter press for secondary dehydration, so that the moisture content of the m...

Abstract

The treatment method for brew waste residue including solid-fluid separating, aerobic fermenting, heating drying, mixing endoplasm and prilling forming to produce fertilizer and adjusting temp. fermenting and chemical mixing endoplasm to provide field irrigation water.

Description

Technical field [0001] The invention relates to an environmental protection treatment method for brewing industry waste, in particular to a method for effectively utilizing the brewing industry waste. Background technique [0002] The waste (waste residue, waste water) produced by the brewing industry (white wine, citric acid, alcohol, beer, vinegar, rice wine, monosodium glutamate, xanthan gum, etc.) To invest a lot of money in governance. These wastes contain a large amount of organic matter and mineral elements mainly composed of cellulose, lignin, organic acids, and proteins. The traditional treatment method is anaerobic fermentation to degrade the organic matter, which is not only difficult to meet the national emission standards , to fundamentally solve environmental protection problems, and the processed products cannot be effectively used, and can only be used for landfill and discharge treatment, occupying space, deteriorating water quality, and causing secondary p...
