Problems solved by technology

[0003] In addition to a huge amount of paper scraps, these wastes also contain more valuable copper, aluminum, magnesium elements, rare earth elements and a small amount of heavy metal elements, etc. These wastes are often treated by centralized incineration or direct landfill, resulting in two Secondary pollution; the above two kinds of garbage are waste products that waste manufacturers disdain to recycle due to the high recycling cost and low recycling rate.

Embodiment 1

[0025] Take 1 ton of waste from fireworks and firecrackers:

[0026] (1) Put 120°C steam into the waste for 10 minutes to sterilize;

[0027] (2) Add 10 tons of water, adopt the ZDS-30 pulper produced by Zhucheng Jinhaiying Environmental Protection Equipment Co., Ltd., 1000r / min to disintegrate, and pass it into the treatment tank to obtain coarse pulp;

[0028] (3) Add dilute sulfuric acid to adjust the pH value of the coarse slurry to 2.0, and inoculate the microbial seed solution containing acidophilic Thiobacillus ferrooxidans, Rhodotorula yunnanensis, and Klebsiella pneumoniae, so that the microbial concentration in the solution is 3.0× 10 6 a / ml;

[0029] (4) Make a carbon cloth anode and a carbon cloth cathode, connect the made carbon cloth anode and the carbon cloth cathode with a copper wire, and put them into a treatment pool; wherein, the carbon cloth anode is made by soaking in concentrated nitric acid Carbon fiber cloth for 5h, then washed with deionized water ...

Embodiment 2

[0040] Take 1 ton of waste from fireworks and firecrackers:

[0041] (1) Put 120°C steam into the waste for 5 minutes to sterilize;

[0042] (2) Add 15 tons of water, adopt the ZDS-30 pulper produced by Zhucheng Jinhaiying Environmental Protection Equipment Co., Ltd., 1000r / min to disintegrate, pass in the treatment tank, and obtain coarse pulp;

[0043] (3) Add dilute sulfuric acid to adjust the pH value of the coarse slurry to 2.0, and inoculate the microbial seed solution containing acidophilic Thiobacillus ferrooxidans, Rhodotorula yunnanensis, and Klebsiella pneumoniae, so that the microbial concentration in the solution is 5.0× 10 6 a / ml;

[0044](4) Make a carbon cloth anode and a carbon cloth cathode, connect the made carbon cloth anode and the carbon cloth cathode with a copper wire, and put them into a treatment pool; wherein, the carbon cloth anode is made by soaking in concentrated nitric acid Carbon fiber cloth for 5h, then washed with deionized water until the...

Abstract

A microbial treatment method of scraps from firework-firecracker set-off comprises the steps of pretreating, pulping, microbial treatment, impurity separation and the like; high-quality pulp and wasteliquid that is rich in aluminum, copper, magnesium and other metal elements are obtained, as well as waste residue having low heavy metal content; scraps from firework-firecracker set-off has a low content of non-combusted active metals and heavy metals inhibitory for microbial activity, solution pH during extracting in the method has a small change, microbial reaction can occur efficiently and continuously, the whole technical process is shortened, and microbial leaching efficiency is improved. The method of the invention has simple process and low cost, produces little wastewater, and has high recycling rate, and leaching rate for copper, aluminum and magnesium is 70% and above, up to 100%.

Description

technical field [0001] The invention belongs to the field of biological treatment, and in particular relates to a microbial treatment method for waste debris produced by setting off fireworks and firecrackers. Background technique [0002] The custom of setting off fireworks and firecrackers and posting Spring Festival couplets during the Spring Festival has a long history in our country. Although more and more big cities have implemented measures to prohibit them during the Spring Festival, the vast number of rural areas and small cities have shown that the amount of fireworks during the Spring Festival has intensified; This has led to a large amount of waste from fireworks and firecrackers during the Spring Festival; taking Jinan City as an example, more than 800 tons of waste from fireworks and firecrackers were generated during the Spring Festival last year in the city, and the highest amount of waste from fireworks and firecrackers in a single day was nearly 100 tons , ...
