Problems solved by technology

[0003] The ideal deodorant is to perform oxidation-reduction degradation to completely remove odorous substances, but in the actual process of disposing of hazardous waste, the cost is high and the feasibility is average. Consider using a stabilization method to combine odorous amines and iron-related compounds. A complexation reaction occurs to generate a chelate compound without a foul smell, and the smell is disposed of

Embodiment 1

[0018] Weigh 500g of the distillation residue of a manufacturer with a bad smell, the water content is 14%, and the reduction rate is 21%. The main bad smell components are triethylamine and isopropylamine. 200g (+ / -5%) of grinding iron filings (cutting mud, grinding mud), adjust pH: 7-9 with lime, stir for 10 minutes for solid phase reaction, after 3 hours, the smell is obviously weakened, and the effect is very good after 1 day Well, to achieve the purpose of removing the smell.

Embodiment 2

[0020] Take by weighing 500g of the distillation residue of the same manufacturer in Example 1, add 50ml of tap water, stir for 5min, add 200g (+ / -5%) of grinding iron filings (cutting mud, grinding mud), add 10g polyaluminum chloride, Zeolite powder 2g, use lime to adjust pH: 7-9, essence 0.5g, stir for 10min, the effect of the same treatment time is better than 1, to achieve the purpose of removing odor.

Embodiment 3

[0022] Take by weighing 500g of the distillation residue of the same manufacturer in Example 1, add 50ml of tap water, stir for 5min, add 200g (+ / -5%) of grinding iron filings (cutting mud, grinding mud), add 20g of polyaluminum chloride, Use lime to adjust pH: 7-9, add 10g of guar gum, 2g of zeolite powder, 1g of alanine, 0.5g of essence and stir for 10min.

Abstract

The invention discloses a deodorant for treating the peculiar smell of pesticide-containing organic amine waste. Amino acid and flavor formation. Compared with the prior art, the present invention has the following advantages: the deodorant can effectively dispose of various malodorous substances such as isopropylamine, triethylamine, butachlor under solid-phase conditions, and is dangerous to various peculiar smells produced by pesticide enterprises. Wastes such as inorganic distillation residues, pesticide-containing sludge, etc. can be effectively disposed of, and the odorous gas can be stabilized to generate corresponding metal complexes and high-boiling compounds, thereby achieving the purpose of removing odors.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to the technology for eliminating the peculiar smell of hazardous waste. Background technique [0002] Odor has become one of the typical public hazards in the world today, which can directly affect people's sense of smell and cause harm to people. The odor pollution produced by landfills is very serious. In addition to incineration, composting or recycling, more than 70% are transported to landfill for disposal, but due to the physical, chemical and microbiological processes in the landfill process and treatment process, a large amount of odor and strong irritating gas are produced. Not only can people have an unpleasant feeling of disgust, but many odorous substances are also harmful to people's health and even life. Irritant odorous gas pollution refers to all gaseous substances that stimulate the olfactory organs to cause people's unpleasantness and damage the l...
