Description
The present invention relates to a food waste multi-stage separation method and a device thereof, wherein the solid-liquid separator is installed in two or more stages, and the filtered water from which the solids are recovered is supplied to another solid-liquid separator together with the replenishment water to separate the solids, thereby recovering the solids. The present invention relates to a food waste multi-stage separation method and an apparatus for improving efficiency.
Food waste is a large amount of waste generated by human life. About 10,000 tons per day is generated, and these food wastes contain about 80 to 85% of water and are mostly organic. Easily rot, but also had the problem of causing bad smell and filth.
Conventionally, in order to solve the problem of food waste disposal, the food waste solid-liquid separation system is installed to pulverize the food generated in the kitchen, separate the solids and water, and discharge, thereby minimizing the volume, weight and decay of the food waste. It is used.
However, the conventional food waste solid-liquid separation system is a system for separating the solid food waste slurry after the solid-liquid separation, and then separating it into solids and water, the conventional food treatment method as described above when separating the solids and water, The efficiency is only about 30 to 40%, and solids are discharged to the sewer with water.
In particular, Korea's food waste related system is largely a law related to food waste reduction equipment, where food waste is less than 20/100 of the weight of solids in which the weight of solids discharged along with the discharged water is recycled through the relevant facility. In accordance with the Waste Management Act and the provisions of Article 33, the sale and use of kitchen waste crushers is prohibited, and the testing and certification procedures of the test institute approved by the Minister of Environment are prescribed in accordance with the provisions of No. 2012-203 No. 2 of the Ministry of Environment. The Sewage Act, a law on kitchen crushers, states that kitchen waste grinders can crush food waste and discharge it with sewage at less than 20% (more than 80%) by weight of solids. However, the conventional food treatment method is difficult to satisfy the above laws, and various practical applications The dots were.
An object of the present invention is to provide a food waste multi-stage separation method and apparatus for adjusting the food waste to an appropriate concentration, and solid-liquid separation in two or more stages to improve the recovery of solids.
In the present invention, after the food waste slurry is solid-liquid separated into solids and filtrate by the first solid-liquid separator, supplemental water is mixed into the filtrate to produce a mixed slurry, and the mixed slurry is supplied to the second solid-liquid separator to provide a solid and a secondary filter water. The solids separated and dewatered in the first and second solid-liquid separators are fed to the food fermentation annihilator and annihilated, and the secondary filtered water discharged from the second solid-liquid separator is discharged to the underground sewer pipe. Food waste multi-stage separation method of the present invention is a storage step of the food waste crushed in the kitchen crusher (10) is mixed with the kitchen sewage transported into the
In the present invention, the solid-liquid separator is installed in multiple stages, and the separated solids are fed into the food fermentation annihilator and annihilated, and the filtrate is mixed with the supplemental water with another solid-liquid separator and then separated into solid-liquid separation. It is intended to increase the recovery efficiency of the solids in the food waste slurry.
The present invention is to recover the solids in the food waste slurry and at the same time mixing / fermenting / extinguishing them with microorganisms, while safely treating the food waste without causing environmental pollution, fueling, fertilizing, feed, etc. of food waste It is possible to recycle through.
In the present invention, since the recovery rate of solids is improved by supplying supplemental water, even if a solid-liquid separator having the same performance is provided in multiple stages, the solids discharge standard by the waste management method and the sewerage method can be satisfied.
The present invention is such that the filter screen and the screen conveyor of the solid-liquid separator are rotated at a high speed in the opposite direction (opposite direction) by one driving motor, thereby improving the dewatering efficiency of the solids and facilitating the space for installation of the solid-liquid separator. Can be.
The present invention can stably recover the solids in the food waste in the residential complex using the kitchen crusher installed in each generation of the apartment house, reducing the amount of solids outflow of food waste discharged to the underground sewer pipe, clogging, odor And there are many effects, such as to prevent the risk of safety accidents.

In the present invention, after the food waste slurry is solid-liquid separated into solids and filtrate by the first solid-liquid separator, supplemental water is mixed into the filtrate to produce a mixed slurry, and the mixed slurry is supplied to the second solid-liquid separator to provide a solid and a secondary filter water. The solids separated and dewatered in the first and second solid-liquid separators are fed to the food fermentation annihilator and annihilated, and the secondary filtered water discharged from the second solid-liquid separator is discharged to the underground sewer pipe.
In this case, the mixed slurry means a state in which supplementary water is supplied to the filtrate discharged through the filtrate outlet from the first solid-liquid separator.
That is, the present invention comprises a storage step of transporting and storing the food waste pulverized in the kitchen crusher mixed with the kitchen sewage;
A slurry holding step of stirring and mixing food waste and kitchen sewage by a stirrer in a storage tank to produce a food waste slurry;
A food waste slurry feeding step of feeding the food waste slurry in the reservoir to the first solid-liquid separator through a soluble pipe by a slurry supply pump;
A first solid-liquid separation step of separating the food waste slurry into solids and filtrate by a first solid-liquid separator;
The solids separated and produced in the first solid-liquid separator is sent to the food fermentation annihilation unit, the filtered slurry is mixed with supplemental water and fed to the second solid-liquid separator in a mixed slurry state;
A second solid-liquid separation step of separating the mixed slurry into solids and secondary filtered water by a second solid-liquid separator;
The first and second solid-liquid separated in the solid-liquid separator is fed to the food fermentation and extinction portion fermentation extinction step of fermentation extinction;
In the mixing slurry supplying step, supplemental water is supplied to the filtered water by the weight of the solid recovered in the first solid-liquid separator.
In the present invention made as described above, about 40 to 50% of the solids in the food waste slurry are recovered by the first solid-liquid separation step and supplied to the food fermentation annihilator, and about 40 to 50% of the solids by the second solid-liquid separation step. It is recovered to some extent and supplied to the food fermentation annihilation unit, which finally recovers about 80% or more of the solids in the food waste slurry.
This is a recovery rate that can never be achieved when the filtrate generated in the first solid-liquid separator is simply supplied into the second solid-liquid separator and solid-liquid separated in the second solid-liquid separator, and the filtered water is replenished to the filtrate by the weight of the solid recovered in the first solid-liquid separator. Only when the water is supplied to the second solid-liquid separator in the state of the supplied slurry.
The present invention made as described above is installed in apartment houses such as large restaurants or apartments, and not only recovers more than 80% of the solids in the food waste generated in each household, but also recovers the solids by fermentation and extinction with microorganisms.
