Abstract
The invention discloses a method for producing solid fuel from swill-cooked dirty oil. The method comprises the following steps of filtering swill-cooked dirty oil to remove impurities, adding a saturated sodium hydroxide solution into the swill-cooked dirty oil according to a certain ratio, carrying out heating for a full reaction, carrying out cooling until gel is not concretionary, adding industrial alcohol and paraffin into the gel according to a certain ratio, carrying out fast stirring to obtain a uniform mixture, pouring the mixture into a mold box and carrying out cooling molding. The method utilizes swill-cooked dirty oil as a raw material to realize production of solid fuel, realizes waste recycle and provides a novel purpose of swill-cooked dirty oil.
Description
Technical field
The present invention relates to a kind of waste utilization method, be specifically related to a kind of method utilizing copper chloride etching waste liquid to prepare micron order cupric oxide.
Background technology
Along with improving constantly of China's electronic industry annual growth, driven printed circuit board (PCB) and related industries development, China has become the printed circuit board (PCB) production center the biggest in the world.Printed circuit board (PCB) etching process produces a large amount of copper-containing etching waste solutions, do not carry out process can cause environmental pollution and cause the wasting of resources, current China on average produces etching waste liquor daily more than thousands of tons of, if copper wherein can be reclaimed, will produce great economic benefit.
Summary of the invention
Technical problem to be solved by this invention is for the deficiencies in the prior art, provides a kind of method utilizing copper chloride etching waste liquid to prepare micron order cupric oxide.
Technical problem to be solved by this invention is realized by following technical scheme.The present invention is a kind of method utilizing copper chloride etching waste liquid to prepare micron order cupric oxide, be characterized in: acidic etching waste liquid being diluted with water to copper ion concentration is 10-20 grams per liter, add glucose, glucose and cupric ion mol ratio are 1:1.5, be placed in the water bath with thermostatic control of 80 DEG C, stir, add sodium hydroxide solution simultaneously.React after 1-2 hour and filter, with absolute ethanol washing, filter cake is placed in the dry 1-2 hour of vacuum drying oven of 50-70 DEG C, be i.e. obtained micron order cupric oxide.
Compared with prior art, the inventive method is reasonable in design, and acidic etching waste liquid not only can be utilized by further, can also prepare high value copper.
