Problems solved by technology

Moreover, if the waste water is treated simply by filtering, some microorganisms, heavy metals and other components that cannot be filtered out will remain in the waste water, which will easily cause problems such as the clean water is not clean enough.

Embodiment 1

[0029] The present invention includes the following stages: after storing the waste water generated in the process of resource treatment in the sump for precipitation, putting the liquid waste water into the solid-liquid separator for primary separation; putting the separated liquid waste water into the heater for heating , use a centrifugal separator to perform secondary separation on the heated wastewater, and separate it into water, oil, and sludge cake three-state substances; store the secondary-separated wastewater in an anaerobic decomposition tank, and store the wastewater Put coagulant into the waste water to remove the sludge contained in the waste water; make the waste water with the sludge removed flow into the dehydrator for dehydration, and put the waste water generated after dehydration into the filter for secondary filtration; The filtered waste water is stored in the sump, and after the last settling, the generated clear water is released to the outside.

Embodiment 2

[0062] Figure 4 is a structural diagram taken from another embodiment of the present invention.

[0063] In the wastewater treatment device according to another embodiment in the accompanying drawings, the activated sludge method is used for the secondary filtration in the original embodiment. It consists of an aeration unit (30) to replace the membrane filter (11) in the original embodiment.

[0064] The aeration unit (30) is installed inside the aeration tank (31, 32) and the aeration tank (31) for storing wastewater, and its composition includes an oxygen supply machine (33) for supplying oxygen.

[0065] The aeration tanks (31, 32) are divided into the first and second aeration tanks (31, 32). The aeration tanks (31) on one side carry out high-load treatment of wastewater, and the wastewater treated with high load enters After the aeration tank on the other side is treated with a low load, the activated sludge is forcibly separated in the aeration tank (32) on the other...

Abstract

The invention relates to a wastewater treatment method in a kitchen waste recycling treatment process. The wastewater treatment method comprises the following steps: storing wastewater, separating and filtering for the first time; heating, separating for the second time; removing sludge; dehydrating; filtering for the second time; and storing effluent. According to the wastewater treatment method in the kitchen waste recycling treatment process, certain microbes which cannot be filtered can be heated and filtered, so that the cleanness degree of drained clear water can reach an ideal standard and has the effect of preventing secondary environmental pollution.

Description

technical field [0001] The invention relates to waste water treatment in the resource treatment process of kitchen waste. Specifically, after the waste water generated during the resource treatment process of food waste is filtered, the solid food waste particles contained in the waste water are re-entered for resource treatment, and the filtered water is released to the external food waste resource treatment process. wastewater treatment methods. Background technique [0002] Today, the rapid development of industry and the improvement of national income have made people's lives gradually richer, and their food life is becoming more and more abundant. However, as people get rid of the backward and poor life, the phenomenon of hunger has been greatly reduced, and the food on the table has become more and more abundant, which has led to a serious increase in the amount of leftover food in the kitchen. [0003] When this kind of food waste is landfilled, a large amount of le...
