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) Use the QKT--400B grain thresher produced by Weihui Dali Machinery Factory to remove the larger soil residue, lime, and gravel particles in the waste, and sterilize the remaining waste with 120°C steam for 10 minutes ;

[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 int...

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

[0041] (1) Use the QKT--400B grain thresher produced by Weihui Dali Machinery Factory to remove the larger soil residue, lime, and gravel particles in the waste, and sterilize the remaining waste with 120°C steam for 5 minutes ;

[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 treat...

Abstract

The present invention provides a microbiological treatment method for sweeps mainly composed of waste produced by fireworks and crackers. Through pretreatment, pulping, microbiological treatment and impurity separation steps, pulp with high quality, liquid waste rich in metallic elements such as aluminum, copper and magnesium, and waste residue with a lower content of heavy metal are obtained. According to the sweeps produced by fireworks and crackers, contents of unburned active metal and the heavy metal inhibiting microbial activity are few, so that variation of the solution pH value duringan extraction process of the method is little, microbial reaction can be performed continuously and efficiently, and therefore the whole technological process is shortened, and microbiological leaching efficiency is improved. The method is simple in technology and low in cost, the produced water waster is little, recovery rate is high, and leaching rates of cooper, aluminum and magnesium can reachmore than 70% 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 garbage mainly generated 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 ...
