Embodiment 1

[0036] A microwave treatment method for chemical waste, comprising the following steps:

[0037] a. According to the weight ratio, take 150 parts of chemical waste and pass it into the reduction pool, add 12 parts of catechin, 5 parts of hydroxylamine hydrochloride, and 5 parts of sodium citrate, mix well, let it stand for 10 hours, and then add nitrilo After 13 parts of sodium triacetate were mixed uniformly, the reaction was continued for 18 hours to obtain the reduced product;

[0038] b. Pass the reduced product into the oxidation tank, add 10 parts of the hydrogen peroxide oxidation residue, mix well and let it stand for 8 hours to react, then add 6 parts of chlorophyll and 7 parts of 8-hydroxyquinoline and mix evenly, continue to stand for 13 hours , to obtain a chelated mixture;

[0039] c. Put the chelation mixture into the microwave cracking furnace, feed in the methane and raise the temperature to 75°C, keep it warm for 45 minutes, then add nitric acid waste liquid,...

Abstract

The invention provides a microwave treatment method for chemical waste, and specifically relates to the technical field of garbage sorting and treatment. In the present invention, the redox method is used to fix the heavy metals in the chemical waste of medical waste, and then the chemical waste is converted into gaseous fuel and harmless of solid matter. The chemical waste treated by the method of the present invention has a weight loss of more than 90%; no nitrogen oxides, heavy metals, carbon monoxide and dioxins are detected in the discharged digestion gas and the introduced biogas; the obtained degradation mixture leachate No heavy metals were detected in the blood, and the five-day biochemical oxygen demand was below 5.3mg / L. The invention has stable process and controllable parameters, and is suitable for industrial application.

Description

【Technical field】 [0001] The invention relates to the technical field of garbage classification and treatment, in particular to a microwave treatment method for chemical waste. 【Background technique】 [0002] Garbage sorting is a reform of the traditional way of garbage collection and disposal, and it is a scientific management method for effective disposal of garbage. Facing the situation of increasing garbage production and deteriorating environmental conditions, how to separate different types of garbage to the greatest extent through garbage classification management, realize the utilization of garbage resources, reduce the amount of garbage disposal, and improve the quality of living environment is the current world One of the urgent issues of common concern to all countries. In addition to daily domestic waste, with the rapid development of my country's healthcare industry, medical waste has increased significantly. For a long time, medical waste has been called the ...
