CZ191693A3 - Method of treating liquid manure and other organic waste - Google Patents

Abstract

This invention involves a method of liquefying and treating organic waste, in particular sludge manure from farm animals, in a biological manner the nature of which is based on the fact that organic waste is mixed with a combination of bentonite or/an zeolite and at least one dried anaerobic or/and facultative anaerobic strain of bacteria of lactic and/or propionic fermentation in a quantity of at least 0.1 kg of the above-mentioned combination per cubic metre of organic waste while one gram of the above-mentioned combination contains at least 10<2> of the vital bacteria. The given combination is added to the organic waste preferably in the form of a suspension in a liquid free of bactericidal and/or bacteriostatic effects against the given bacteria, in particular in a nutrient solution, for example in whey.

Description

The present invention relates to a method of treating livestock manure and other organic waste biologically by using cultures of anaerobic and facultatively anaerobic bacteria in combination with an inorganic binder.

BACKGROUND OF THE INVENTION

So far, livestock manure has not been treated in the stables, which has led to a severe environmental degradation by concentration of ammonia in the air, clogging of undergrowth channels, nutrient losses and deposits in the sump.

To improve the situation, mainly to release the channels, water spraying is used, possibly in combination with laborious and costly mechanical cleaning, which in many cases has been unable to release the grit and drain channels and to dissolve the sediment in the wells. the waste slowly and inappropriately ripens, making it unsuitable for use as field fertilizer or for composting.

These deficiencies are eliminated by biological treatment of livestock manure and other organic waste.

SUMMARY OF THE INVENTION

Delivered dried cultures of anaerobic and facultative anaerobic bacteria, which by their activity ensure appropriate maturation of slurry and other organic wastes and reduce rotting aerobic processes. An inorganic binder, such as bentonite, binds ammonium cations, thereby increasing the nitrogen content of the slurry and eliminating odors in stables and in storage areas. This improves the quality of organic fertilizers and can be used in the form of fertilizer irrigation, for the composting of less suitable organic waste materials such as old straw, etc.

Dry and freeze-dried bacterial cultures are used in combination with organic pulverulent powders for direct treatment of slurry and other organic waste by sprinkling or spraying after dissolution in water or whey. In whey, this combined biological preparation is allowed to rest for a period of time after mixing to activate the efficacy of bacterial cultures.

Preferably, the addition of biodegradable manure is used in the composting process. This slurry is applied to the stratified composted material, such as old straw, organic waste, etc., while homogenizing the material.

EXAMPLES OF EMBODIMENTS OF THE INVENTION

EXAMPLE 1

Dried powder culture of anaerobic and facultative anaerobic bacteria mixed with inorganic binder by spraying on grates or bedding in the amount of 2 kg per 1m ^{3 of} slurry is applied for treatment of manure of farm animals in stables

EXAMPLE 2

For the treatment of livestock livestock dissolves in the required amount of water 1 kg of dried bacterial culture mixed with an inorganic binder per 1 m ^{3 of} manure and the solution is sprayed with grates and flushing undergrowth and drainage channels

EXAMPLE 3

Dried bacterial cultures with organic matter are sprayed on the surface of the slurry mass in an amount of 1 kg per 1 m ^{3 of} slurry for the treatment of slurry in wells. After application, mix the contents of the well

EXAMPLE 4

Ph composting or digging of compost is applied biologically treated slurry in five times the amount of compost organic matter

EXAMPLE 5

Dried bacterial culture mixed with an inorganic binder is poured into places where animal excrements are collected as needed to reduce odor and improve the environment

EXAMPLE 6

The dried bacterial culture mixed with an inorganic binder is poured into the faecal wells or into the dry wells of municipal buildings. The sump contents can then advantageously be used for fertilization

Example 7

A mixture of bacterial cultures and inorganic binders after dissolving in whey and keeping the required temperatures at the temperature is applied to treat the slurry in the wells.
