CZ191194A3 - Process of disposing waste from the production of olive oil - Google Patents

Abstract

The way of disposal of waste from olive oil production using intensive grinding and mixing of effluent water with natural bentonite, which is thus activated. The solution is based on a continuous mixing of the liquid phase of waste, whose density is between 800 to 1000 kg/m<3>, at a ratio of up to 300 kg of natural bentonite, to 1 m<3> of the liquid phase of waste, followed by the admixture of solid phase of waste after which the mixture is inoculated and subject to forced aeration.

Description

Waste disposal method 2 of olive oil production

Technical field

The invention relates to a process for the disposal of olive oil waste 2.

BACKGROUND OF THE INVENTION

The production of olive oil takes place in two pressing plants situated in the vicinity of olive groves. The oil is pressed with 2 olive pulps, or 2 olive pomace or 2 olive kernels. The waste resulting from the olive oil production process is the compressed mass of 2 flesh, husks, shells of kernels, leaves and twigs of twigs, and also the juice that has been left after the oil has been separated. So far, this waste has been disposed of by burning the solid parts on site and pouring the juice, named in the technological process for the production of the olive environment, since the construction of the oil juice as marga, the digester contains, among other things.

a significant proportion of the cost group is considered to be natural. phosphate ids subject to putrefaction processes.

They cause environmental damage - odor spread, water and soil contamination.

Other possible ways of disposing of organic waste are known from the literature, for example by seeding them with cattle sludge or sewage sludge, which should have an effect on the multiplication of methanogenic bacteria and thus on the production of biogas. However, because biogas production was not constant and sometimes disappeared, for example, vaccination with rumen contents or rumen fluids obtained from slaughtered animals was tested. While this has allowed the control of bacterial activity to some extent, such a method is not commonly applicable for the purposes of waste disposal of the composition and location described above.

There are also known chemical procedures for disposal of similar waste, eg acids with subsequent neutralization, which, however, are very expensive and complicated and, in addition, carry the risk of overdose and thus environmental damage.

basically their pyrolytic contained a certain proportion

For example, another method is to dispose of the sludge after wine clarification, the so-called blue sludge. This procedure depends on the calcination of the sludge at high temperatures, i.e. by decomposition. It is utilized that bentonite is present in the sludge and the end product can then be used as an additional raw material in the brick, ceramic, cement and other industries. Even this method of disposal is not realistic for the purpose of the invention since it assumes the proximity of the high-temperature source and the content of e.g.

ferrocyanides in the waste so that it can occur and grinding and mixing all needed

SUMMARY OF THE INVENTION

These deficiencies are essentially eliminated by the method of waste disposal of olive oil production, which utilizes intensive milling and mixing of waste water with natural bentonite, thereby activating it.

The liquid waste phase, which has a density of 800 to 1000 kg / m ³ , is continuously mixed at a rate of up to 300 kg of natural bentonite per m ^{3 of} liquid waste phase, the solid waste phase is admixed and the mixture is mixed. inoculate and undergo forced aeration.

The advantage of the olive oil waste disposal method is a simple and inexpensive device, which can be, for example, only a pump tank, the absence of chemicals, and the availability of raw materials and energy, particularly suitable, can easily be prepared from soil inoculum material. It contains microorganisms modified in the long term by the action of animal products and also by degradation measures. the lumpy mass, which is therefore provided with a specific end product, is a loose material suitable for agricultural use.

The material does not decompose and does not smell even in humid environments.

DETAILED DESCRIPTION OF THE INVENTION

The waste disposal method according to the invention has been utilized in operating conditions.

Waste from the production of olive oil in the composition of 28.6 wt. % olive pomace, 17 ^ 4 wt. % of olive juice after separation from oil, so-called niargy, 54 wt. % of vegetable waste, ttarga, as the liquid phase of waste with a density of 970 kg / m ³ , was treated by mixing with natural bentonite coming from 2 Obrnice deposits, namely f

«At a rate of 200 kg of bentonite per m ^{3 of} marga. The mixture was further stirred with _w solid phase, i.e. with moldings and vegetable waste for post inoculation material. The inoculation material was obtained by first collecting 25 kg of top soil from the immediate vicinity of the olive tree and mixing well with 55 l of freshwater untreated water. After the insoluble matter was sedimented, the aqueous portion was discarded and used immediately.

The treated composting batch at 31 ° C was charged into a controlled aeration mode bioreactor and measuring the carbon dioxide concentration of the bioreactor offgas.

The temperature of the deposited waste reached a maximum value of 65 ° C after 7 days and at the same time the carbon dioxide content rose to a maximum during the whole process. For the next 7 days the values of both of these monitored parameters decreased. The temperature of the composted material then did not exceed 45 ° C in the final phase. indicating accelerated decomposition of bio-matter.

The appearance of the product clearly suggests that the quality of the raw materials was proreagent. No decomposition processes, which normally accompany the digestion of olive wastes to produce undesirable, highly odorous volatile substances, have occurred during or after the fermentation.
