Embodiment 1

[0038] A method for harmless treatment of chemical waste and pharmaceutical waste, comprising the following steps:

[0039] a. Take 155 parts of chemical waste and pass it into the reduction pool, add 13 parts of catechin, 5 parts of hydroxylamine hydrochloride, and 6 parts of sodium citrate, mix well, let it stand for 9 hours, and then add 12 parts of sodium nitrilotriacetate After mixing evenly, continue to stand still for 17 hours to obtain the reduced product;

[0040] b. Pass the reduced product into the oxidation tank, add 11 parts of the hydrogen peroxide oxidation raffinate, mix well and let it stand for 9 hours to react, then add 5 parts of chlorophyll and 8 parts of 8-hydroxyquinoline and mix evenly, continue to stand for 11 hours , to obtain a chelated mixture;

[0041] c. Pass the chelation mixture and the pharmaceutical waste together into the microwave cracking furnace, feed in the methane and raise the temperature to 71°C, keep it warm for 43 minutes, then add ...

Abstract

The invention provides a harmless treatment method for chemical waste and pharmaceutical waste, and particularly relates to the technical field of garbage classification treatment. According to the method, when chemical waste and pharmaceutical waste are treated, heavy metal is firstly fixed through an oxidation-reduction method, and then the waste is converted into gas fuel through an acid pre-digestion and microwave and alpha ray combined digestion method; and four kinds of bacteria including proteus mirabilis, bifidobacterium, bacillus thuringiensis and cyanobacteria are added into an obtained degradation mixture to be cultured and separated so that final solid particles can be used for preparing fertilizer, and no pollution is caused to the environment. The weight of the chemical wasteand pharmaceutical waste treated by the method is reduced by more than 85%; oxynitride, carbon monoxide and dioxin are not detected in discharged digestion gas and introduced biogas, and no heavy metal is contained; and no heavy metal is detected in an obtained solid particle leaching solution. According to the method, the process is stable, parameters are controllable, and the method is suitablefor industrial application.

Description

【Technical field】 [0001] The invention relates to the technical field of waste classification and treatment, in particular to a method for harmless treatment of chemical waste and pharmaceutical 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 ever-increasing garbage output and deteriorating environmental conditions, how to maximize the separate treatment of different types of garbage 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 ...
