Abstract

The present invention relates to a method for producing a raw material capable of treating livestock wastewater using waste paper discharged from household waste.

Conventionally, sawdust is applied to livestock barns to absorb wastewater and wastewater and fertilized through fermentation process. However, the supply of sawdust does not meet demand and the high price and the limit of the maintenance rate of sawdust. There were problems such as having to use.

In the present invention is to develop a replacement material for sawdust by processing waste paper with excellent repair rate suitable for livestock wastewater treatment raw material, to obtain a pulp by dissociating the waste paper discharged as household waste to a certain size using a dry paper disperser;

Starch, water-soluble resin (PVA, EVA) and the like are added to the pulp, mixed in a mixer, and then molded and dried by pellets.

The present invention can produce a livestock wastewater treatment raw material using waste paper, and can simultaneously process waste and livestock wastewater, and has the effect of stably supplying livestock wastewater treatment raw materials.

Description

Livestock wastewater treatment raw material manufacturing method using waste paper.

The present invention is for producing livestock wastewater treatment raw materials from waste paper discharged as household waste, more specifically, the livestock wastewater treatment raw material which can be utilized as organic fertilizer or composting by absorbing livestock wastewater discharged to livestock farms It is about giving.

Generally, wastewater purification facilities are used to treat livestock wastewater. However, in the case of small farmers, it is not possible to have a costly purification facility. The method of processing is widely used and the processing method is as follows.

In the livestock wastewater treatment, it is a common treatment method that sawdust is used as a rug in a livestock house to absorb and recover the wastewater and wastewater generated in the livestock farming process, and then fermented and used as organic fertilizer.

As mentioned above, there is a huge increase in the demand for using sawdust in many livestock farms due to the characteristic that the wastewater generated in the barn can be recycled as fertilizer using sawdust without using a separate purification facility. Sawdust supply is less than demand.

As a result, the price increase is a problem, and in the case of sawdust commercially distributed due to the limitation of the maintenance rate, there are disadvantages such as enormous amount of wastewater treatment.

Accordingly, the present invention is intended to provide a livestock wastewater treatment raw material having a high maintenance rate by using waste paper unused in the municipal waste instead of sawdust as a raw material for livestock wastewater treatment.

To this end, in the present invention, the waste paper not currently used in the city waste is dissociated dry using a dry paper dissociator to obtain de-sealed pulp, and livestock using an adhesive such as starch and water-soluble resin (PVA, EVA) on the pulp and the pulp. It is characterized by preparing wastewater treatment raw materials.

Hereinafter, the method of the present invention will be described in detail by process according to a preferred embodiment.

In the present invention, the waste paper not currently used in the city waste is dissociated dry using a dry paper dissociator to obtain de-sealed pulp, and pulp and livestock waste water treatment using starch, water-soluble resin (PVA, EVA), etc. Manufacture raw materials.

Starch, water-soluble resin (PVA, EVA) and the like can be added to the dissociated pulp to increase the moisturizing rate and to produce pellets for long-term use. You may manufacture into a pellet.

Example 1;

First step (dissociation step of the page)

Waste paper is removed using a dry paper dissociator.

When dissociating waste paper through dry paper dissociation, the dissociation speed is 500 to 5000 rpm and the dissociation time is 5 to 30 minutes, but this is somewhat different depending on the type of waste paper, and is not necessarily required. Therefore, the dissociation condition of the paper can be adjusted according to the type of paper.

2nd process (manufacturing process of livestock wastewater treatment raw material)

100 g of the pulp dissociated in the first step is added with 100 to 200% of water to the pulp weight, mixed by stirring in a mixer, and then the blended pulp is dispersed to prepare pellets. Drying for 24 hours produces livestock wastewater treatment raw materials.

Example 2;

First step (dissociation step of the page)

Waste paper is removed using a dry paper dissociator.

When dissociating waste paper through dry paper dissociation, the dissociation speed is 500 to 5000 rpm and the dissociation time is 5 to 30 minutes, but this is somewhat different depending on the type of waste paper, and is not necessarily required. Therefore, the dissociation condition of the paper can be adjusted according to the type of paper.

2nd process (manufacturing process of livestock wastewater treatment raw material)

100 g of the pulp dissociated in the first step is mixed with 1% to 3% of the adhesive (starch, water-soluble resin; PVA, EVA) with water content of pulp by stirring in a mixer, and then the blended pulp is dispersed and pelletized. To prepare a livestock wastewater treatment raw material by drying for 3 hours to 24 hours at a temperature of room temperature ~ 100 ° C.

The livestock wastewater treatment raw material prepared as described above is crushed into a certain size by placing the livestock wastewater treatment raw material of pellet type on the bottom of the livestock farm so that the livestock wastewater treatment raw material absorbs the sewage and wastewater of the livestock house.

The livestock wastewater treatment raw material that absorbs the wastewater is collected and subjected to fermentation, etc., so that it can be utilized as an organic fertilizer.

In the case of the livestock wastewater treatment raw material of the present invention, since the moisturizing rate is larger than that of the conventional sawdust because the raw material is waste paper, the livestock wastewater can be treated using a small amount of the livestock wastewater treatment raw material.

The present invention can be supplied at low prices by replacing the expensive sawdust that is used as raw material for livestock wastewater treatment as well as environmental conservation and cost reduction by using unused waste resources among urban wastes. That has the effect.

Claims (2)
