Description

Desorption of food waste and high concentration wastewater treatment system {WASTE WATER PROCESSING SYSTEM OF FOOD AND DRINK}

The present invention aggregates, pressurizes, and dehydrates high-density wastewater generated from wastes such as collected foods to desorb wastewater, and the wastewater is removed from the wastewater to a fermentation means for fermentation, and the dewatered wastewater is dewatered and pressurized. The present invention relates to a degreasing solution and a high concentration wastewater treatment system for a food waste containing a large amount of milk fat which can efficiently treat a high concentration wastewater such as a desorption liquid desorbed from the food waste by allowing it to be purified while floating.

In general, food waste or various wastes cannot be disposed of as they are. Therefore, the wastes can be separated, incinerated or recycled, and the wastes can be dried and recycled as industrial resources. In particular, the food waste was made into a sludge state, and the collected food waste was stored in a silo to be sent to an incinerator or a drying furnace.

In addition, since the food waste contains a lot of water, only the method of drying and incinerating the food waste could not evaporate or treat all of the wastewater contained in the food waste, and thus, in the food waste The wastewater generated was discharged as it is, and there was a wastewater that caused pollution of the water by the wastewater discharged.

In addition, when the food waste is landfilled as it is, wastewater generated from the food waste is infiltrated into the ground, which causes a problem of lighting that contaminates the land together with groundwater contamination by leachate.

The present invention has been made in view of the above-mentioned conventional problems, the present invention is agglomerated and pressurized, dewatered high concentration wastewater generated from the collected waste, such as food wastes to remove the waste water and the food waste from which the waste water is removed By moving to the fermentation means for fermentation, the dewatered wastewater is dehydrated and pressurized to purify the high-density waste foods such as desorption liquor from the food waste, so as to efficiently treat It is intended to provide a desorption liquid and a high concentration wastewater treatment system, which will be described below in detail with reference to the accompanying drawings.

The dehydration means (4) is connected to the coagulation tank (1) to which the positive and negative ion tanks (2) and (3) are connected, and the dewatering means is dewatered to desorb the waste water to thereby remove the first treatment tank (5). The wastewater transferred to the first treatment tank 5 is transferred to the flotation separator 7 through the pipe flocculator 6.

The flotation separator (7) floats the wastewater by flotation to separate the sludge contained in the wastewater, and the sludge and the wastewater separated from the flotation separator (7) are fed into the raw water storage tank (8) and the secondary storage tank (9), respectively. Send it.

The pipe flocculator 6 is connected to the flocculant dissolving means 10, the admixture tank 11, and the neutralizer tank 12 to which water is supplied, and is processed from the first treatment tank 5, thereby allowing the flocculator 7 to float. Wastewater transported to the c) is agglomerated in the pipe agglomerator (6), and the secondary storage tank (9) is connected to the wastewater purification treatment means (13), which is a biological treatment means, to purify the desorption liquid removed from the food waste and surplus. By connecting the sludge conveying treatment means 14 is to promote efficient purification and to discharge it to the discharge unit (15).

Hereinafter will be described the working state of the present invention configured as described above.

When the wastes ionized through the positive and negative ion tanks 2 and 3 are supplied to the dewatering means 4 while being agglomerated in the agglomeration tank 1, the dewatering means 4 pressurizes the wastes from the food waste. The wastewater is desorbed, and the food waste from which the wastewater is desorbed is transferred to the fermentation copper.

The dewatered wastewater is sent from the dewatering means (4) to the first treatment tank (5), and the first treated wastewater (5) is treated as a flotation separator (7) through a pipe agglomerator (6). In the pipe agglomerate 6, the flocculant dissolving means 10, the admixture tank 11, and the neutralizer tank 12 supplied with water are sequentially connected to the pipe agglomerator 6 to supply the treatment agent and the wastewater supplied therefrom. The mixture is transferred to the flotation separator (7) while mixing and flocculating.

In the flotation separator (7), the transported wastewater is floated by flotation to separate sludge contained in the wastewater, and the sludge and wastewater separated in the flotation separator (7) are respectively stored in the raw water storage tank (8) and the secondary storage tank (9). In the raw water storage tank (8), the wastewater containing sludge is sent back to the flocculation tank (1) for reprocessing, and the wastewater sent to the secondary storage tank (9) is a wastewater purification treatment which is a biological treatment means. The waste water purifying means 13 is transferred to the means 13 to purify the desorption liquid and the high concentration wastewater desorbed from the food waste, and to discharge it to the discharge part 15, and the excess sludge after the purifying action The surplus sludge conveyance processing means 14 is used for conveyance processing.

As described above, the present invention separates waste and wastewater by agglomeration, pressurization, flotation and biological treatment of wastewater such as moisture contained in food waste as described above, and purifies the wastewater to be separated and desorbed to purify. The food waste from which the water has been removed can be fermented to be recycled, thereby preventing environmental pollution caused by the food waste, and by clarifying and discharging the waste water, the leachate of the food waste remains as it is. It has a characteristic of lighting that can be prevented from being contaminated and contaminated groundwater, water and sewage, and land.
