Embodiment 1

[0026] When utilizing pig manure and other organic wastes to produce organic fertilizers, the composition of the added heavy metals relative to the failure treatment agent is as follows by weight percentage:

[0027] Ash 20%

[0028] Quicklime 50%

[0029] Sodium Hydroxide 1%

[0030] Potassium Hydroxide 6%

[0031] Brown sugar 3%

[0032] Bran 20%.

[0033] How to use: Mix pig manure with other organic wastes (including domestic garbage, edible fungus residues, crop straws, medicine dregs and other organic wastes) in a weight ratio of 8:2, and mix according to the total amount of pig manure and other organic wastes to be treated. The ratio of 0.6% of the weight is added with a heavy metal relative failure treatment agent, fermented and decomposed by aerobic microorganisms, and made into an organic fertilizer.

Embodiment 2

[0035] When utilizing chicken manure and other organic wastes to produce organic fertilizers, the composition of the added heavy metal relative failure treatment agent is as follows by weight percentage:

[0036] Ash 20%

[0037] Quicklime 60%

[0038] Sodium Hydroxide 1%

[0039] Potassium Hydroxide 5%

[0040] Brown sugar 4%

[0041] Sawdust 10%.

[0042] How to use: Mix chicken manure with other organic waste (including domestic waste, edible fungus residue, crop straw, medicinal residue and other organic waste) in a weight ratio of 8:2, and mix chicken manure and other organic waste according to the total amount of chicken manure and other organic waste to be treated. The ratio of 0.5% is added with heavy metal relative failure treatment agent, fermented and decomposed by aerobic microorganisms, and made into organic fertilizer.

Embodiment 3

[0044] When using domestic garbage and other organic wastes to produce organic fertilizers, the composition of the added heavy metals relative to the failure treatment agent is as follows by weight percentage:

[0045] Ash 10%

[0046] Quicklime 70%

[0047] Sodium Hydroxide 2%

[0048] Potassium Hydroxide 5%

[0049] Brown sugar 3%

[0050] Wheat Bran 10%.

[0051] How to use: Mix domestic garbage with other organic wastes (including poultry manure, edible fungus residues, crop straws, medicine dregs and other organic wastes) in a weight ratio of 8:2, and mix according to the total amount of pig manure and other organic wastes to be treated. 1% of the weight is added with a heavy metal relative failure treatment agent, fermented and decomposed by aerobic microorganisms, and made into an organic fertilizer.

Abstract

The invention provides a heavy metal relative-inactivation treating agent which relates to the innocent treatment and the resource recycling of organic waste materials. The finishing agent comprises plant ash, quicklime, sodium hydroxide, potassium hydroxide and brown sugar. The treating agent has the advantages of no toxicity, high efficiency and no environmental pollution. The invention also provides a use method of the heavy metal relative-inactivation treating agent.

Description

Technical field: [0001] The invention relates to the harmless treatment and resource utilization of organic waste, in particular to a heavy metal relative invalidation treatment agent for inactivating heavy metals in organic waste and a use method thereof. Background technique: [0002] Using organic waste to make organic fertilizer is a common method of harmless treatment and resource utilization of organic waste. If the heavy metals in the organic waste cannot be harmlessly treated, the produced organic fertilizer will have excessive heavy metal content, resulting in the contamination of crop products. Invention content: [0003] The object of the present invention is to provide a non-toxic, efficient and pollution-free heavy metal relative invalidation treatment agent for invalidating heavy metals in organic waste. Another object of the present invention is to provide a method of using such a treatment agent. [0004] The purpose of the present invention is achieved l...
