Kitchen wastewater purification device and purification method thereof

Abstract

A kitchen wastewater purification device comprises a wastewater purification device, a vegetable leaf chopping device and a composting device which are sequentially arranged from left to right, the vegetable leaf chopping device comprises a shell, a barrel fixedly arranged at the top of the shell, a motor I fixedly arranged at the top of the barrel and a partition plate fixedly arranged in the barrel, and the top of the barrel is closed; a filter plate is arranged in the shell, a valve A and a valve B are respectively arranged on the left side wall and the right side wall of the shell, the valve A is arranged below the filter plate, and the valve B is arranged above the filter plate; the wastewater purification device comprises a purification column, a motor II and a bearing seat, a rotaryjoint is connected to a water inlet of the purification column, and a material pump is connected between the valve B and a feeding hole of the composting device. The kitchen wastewater purification device has the beneficial effects that the structure is compact, the composting efficiency is improved, the salvage efficiency of waste vegetable leaves is improved, purified water capable of being directly drunk can be made, and the operation is simple.

Description

technical field [0001] The invention relates to the technical field of kitchen wastewater purification, in particular to a kitchen wastewater purification device and a purification method thereof. Background technique [0002] Vegetables are an indispensable and important part of the human body. Before eating vegetables, they need to be washed with clean water. After washing, vegetables can be eaten. After each washing, a large amount of wastewater will be generated. There are sludge, organic chemicals in the wastewater Therefore, people salvage all the vegetable leaves remaining in the wastewater, dump the collected vegetable leaves into plastic buckets after salvage, and dump the remaining wastewater directly into the sewer, which is undoubtedly a waste of water resources . When the plastic bucket is full of vegetable leaves, the staff will transport the plastic bucket to the compost pool in the designated processing workshop, and then the workers will pass a certain amou...

AI Technical Summary

Problems solved by technology

[0003] Although the above method for treating waste water can effectively utilize the waste vegetable leaves, there are still the following defects: 1, people need to manually salvage the vegetable leaves in the waste water, which undoubtedly reduces the salvage efficiency and increases the labor intensity

2. The remaining wastewater is directly discharged into the sewer or ditch, which is undoubtedly a waste of water resources. In order to make full use of water resources, people pass the wastewater into the purification column, and filter out the sludge and organic chemicals in the wastewater through the purification column. substances, so as to obtain directly drinking water, but the waste water flows through the purification column for a very short time, resulting in the organic chemicals and sludge in the waste water not being completely treated, so the pure water obtained is unqualified

3. Although the current compost ponds can obtain fertilizers, due to the large volume of vegetable leaves, the contact area between vegetable leaves and microorganisms is small, resulting in the need for a long time for microbial bacteria to completely decompose vegetable leaves, thereby reducing composting. efficiency
