Embodiment 1-6

[0018] Example 1-6 Heavy Metal Stabilizer for Anaerobic Fermentation Residue of Household Garbage

[0019] Embodiment 1-6 is respectively a kind of domestic waste anaerobic fermentation residue heavy metal stabilizer, as shown in table 1, when preparing the domestic waste anaerobic fermentation residue heavy metal stabilizer of 100kg respectively for embodiment 1-6, each raw material Components, and the specific amount required according to the proportion.

[0020] Peat 69.5~79.5%, zeolite 20~30%, heavy metal chelating agent 0.5~1%

[0021] Table 1 Embodiment 1-6 raw material composition

[0022]

Embodiment 7

[0023] Example 7 Preparation method of heavy metal stabilizer for anaerobic fermentation residue of domestic garbage

[0024] This embodiment is a method for preparing a heavy metal stabilizer for anaerobic fermentation residues of domestic waste in any one of Examples 1-6. The raw material components and proportions are composed of any one of Examples 1-6. The preparation method is:

[0025] S1. Grinding peat into peat powder with a fineness of 120 meshes, and grinding zeolite into zeolite powder with a fineness of 140 meshes;

[0026] S2. After mixing peat powder, zeolite powder, and heavy metal chelating agent, a heavy metal stabilizer for the anaerobic fermentation residue of domestic garbage is obtained.

[0027] In this embodiment, the heavy metal chelating agent is a purchased heavy metal chelating agent that meets international standards. After the preparation is completed, the obtained heavy metal stabilizer from the anaerobic fermentation residue of domestic garbage ...

Embodiment 8-13

[0028] Example 8-13 Preparation method of heavy metal stabilizer for anaerobic fermentation residue of domestic garbage

[0029] Examples 8-13 are respectively a preparation method of a heavy metal stabilizer for anaerobic fermentation residues of domestic waste, and their preparation steps are the same as in Example 7, except that the operating parameters in the preparation process are different, and the corresponding mesh number is formulated during preparation. The sieve, concrete operating parameters are as shown in table 2:

Abstract

The invention belongs to the field of household garbage resourceful treatment, and discloses a heavy metal stabilizer for anaerobic fermentation residues of household garbage, which comprises the following components in percentage by mass: 69.5-79.5% of turf, 20-30% of zeolite and 0.5-1% of a heavy metal chelating agent. Wherein the water content of the turf and the zeolite is lower than 15%; theinvention further discloses a preparation method of the stabilizing agent for the heavy metals in the anaerobic fermentation residues of the household garbage. The heavy metal stabilizer for preparingthe organic matter anaerobic fermentation residues in the household garbage can prevent and solve the problem of heavy metal pollution hidden danger of the organic matter anaerobic fermentation residues in the household garbage in liquid or solid organic fertilizer production and use.

Description

technical field [0001] The invention belongs to the field of domestic waste resource disposal, and in particular relates to a heavy metal stabilizer for anaerobic fermentation residue of domestic waste and a preparation method thereof. Background technique [0002] Heavy metals are a kind of highly toxic and potentially harmful inorganic pollutants, which can be enriched in soil and organisms. With the rapid development of my country's economic construction and urban construction, the urban population is constantly increasing, and people's living standards are improving, and the domestic waste produced is also increasing day by day. Household garbage is susceptible to direct pollution from metal ions leaching from batteries in garbage and various living materials with metal plating on the surface, as well as heavy metals in the use and disposal of various raw materials such as paper, paint, ink and dyes containing heavy metal components. The release of ions pollutes, and th...
