Embodiment Construction

[0018] The present invention will be further described in detail through specific implementation examples below.

[0019] A method for recycling and treating kitchen waste after desalination provided by the present invention specifically comprises the following steps:

[0020] (1) Collect, recycle and sort the food waste, and separate the oil layer in the recovered food waste;

[0021] (2) Crushing the food waste generated after separation into fine slurry;

[0022] (3) The crushed slurry is sterilized at 100-120°C for high temperature instantaneously, and a pH regulator is added to the sterilized slurry to make the pH value reach and maintain at 3.5-4.5 or 9-10;

[0023] (4) Electrolyzing the adjusted slurry in step 3, and electrolyzing the slurry in step 2 into hypochlorite;

[0024] (5) When the salt content in the food waste reaches the standard value, add the pH regulator again to adjust the pH value to 6-8, and stop the electrolysis;

[0025] (6) Separating the slurry...

Abstract

The invention discloses a method for recycling kitchen waste after salt removal, and relates to the technical field of garbage disposal engineering. The method specifically comprises the following steps: (1) collecting the kitchen waste, performing recycling, performing sorting, and separating an oil layer in the recycled kitchen waste; (2) crushing kitchen waste generated after separation to formfine slurry; (3) performing instantaneous sterilization on the crushed slurry at high temperature of 100-120 DEG C, and adding a pH regulator into the sterilized slurry to make a pH value reach and maintained at 3.5-4.5 or 9-10; (4) electrolyzing the adjusted slurry obtained in the step 3, and electrolyzing the slurry obtained in the step 2 to form a hypochlorite; and (5) after the salt content in the kitchen waste reaches a standard value, adding a pH regulator to adjust the pH value to 6-8, and stopping electrolysis. According to the method provided by the invention, the obtained natural fertilizer can be recycled, and treated swill can meet a national emission standard in China.

Description

technical field [0001] The invention relates to the technical field of garbage treatment engineering, in particular to a method for recycling and treating kitchen garbage after desalination. Background technique [0002] Kitchen waste mainly refers to the organic waste generated in the catering industry, canteens and family cooking and dining, and generally includes leftovers, kitchen raw material scraps, melon peel and fruit scraps, etc. The main components include starch, protein, oil, dietary fiber and other organic components, which have the characteristics of high water content, high oil and salt content, and are easy to rot and smell. With the improvement and improvement of people's living standards, the amount of kitchen waste is increasing. [0003] Since food waste has three high attributes of "high moisture", "high salt" and "high fat", its first major feature is that it contains more than 75% moisture. Therefore it is difficult to carry out incineration and buri...
