The construction materials are manufactured by mixing the above components, extruding the mixed paste in a brick shape, and drying at 200deg.C.

Description

Process of manufacturing construction materials using scwage sludgc and powdered wastcwater}

The present invention is a method for producing a building interior and built-in brick using sewage sludge and waste paper powder. Currently, sewage sludge is mostly organic, so it is not only light when dried but also has a warming effect. The present invention uses a natural salt to sterilize bacteria contained in domestic sewage without using chlorine, which is harmful to the factor, so that it is a reducing agent while mixing potassium permanganate, a powerful oxidizing agent, to remove odor while enhancing sterilization and defense effects. Since ferrous sulfate is used, potassium permanganate and ferrous sulfate have the most deodorizing effect, the price is low, and the sterilizing and deodorizing effect of potassium permanganate itself must be used. Therefore, while using mixed ammonium chloride as a preservative and mixed with the sewage sludge by using the crosorot oil as a preservative, the waste paper which is the main point of the present invention is used by pulverizing and mixing in a grinder with a blade so that the water contained in domestic sewage At the same time, lungs that can increase crosslinking, filling and warming effect while adsorbing Mix and use the horses to make the building interior and brick frame to make the present invention to extrude and dry in 200 ° C high heat to make the building interior and interior brick using the living sewage sludge of the present invention living sewage sludge When buried in the back is used to stimulate water quality with leachate, etc. and economic burden is large The present invention is to make the use of domestic sewage sludge and to make a building interior materials and interior bricks.

The present invention is to solve the problems as described above by grinding the waste paper powder to adsorb the water contained in the domestic sewage sludge to make the building sewage for the building and the built-in bricks, such as sawdust to make the domestic sewage sludge While mixing with paper, sterilization, deodorization, flame retardant, anti-corrosion treatment, building interior and insulation to be manufactured by making bricks, etc., extruded into a 200 ° c dryer and dried to produce construction materials using domestic sewage sludge of the present invention To provide a way.

The main point of the present invention for achieving the object as described above is to calculate the solid content 40kg of dyeing sewage sludge 100kg (60% moisture) while mixing 20kg of waste paper powder mixed with 2kg of natural salt and potassium permanganate, water 500ml 200g While mixing and dissolving 1 kg of ferrous sulfate (40%) and 1 kg of ammonium chloride as flame retardant, dissolve in 1000 ml of water, and add 500 ml of croissant ointment as a preservative to the material mixed with the waste sludge and waste paper powder. do. When the particles of the pulverized paper powder are mixed to adsorb the waste sludge and spread out invisibly, it becomes a semi-solid field having excellent crosslinking. Making a mold of the building interior to make the semi-solid length is extruded and dried in a 200 ° c dryer to make a light and filling effect, as well as excellent building insulation such as Schiropol. The main point of the present invention was used to make waste paper powder by pulverizing waste paper, thus completely eliminating moisture, which is the biggest problem in recycling domestic sewage sludge, and could be used as a building insulation and interior agent. In addition, the use of chlorine-based chemicals as a disinfectant did not use chlorine as a cause of carcinogenicity, and the use of salt does not rot or worms due to the fact that our ancestors used wood in salt water. There was also an effect, so I chose salt. In addition, low cost and strong oxidizing potassium potassium permanganate as a deodorant, while ferrous sulfate has an excellent effect on potassium permanganate as a reducing agent was used simultaneously. In addition, the flame retardant was used a known drug. In addition, it did not pay much attention to sterilization of the living sewage sludge and waste paper powder of the present invention in the last process of the interior of the interior of the building material was dried at 200 ° C high heat in the dryer, everything was sterilized and did not use a special fungicide. You can also mix and match dyes to create your own color. An embodiment of the present invention having the above characteristics will be described in more detail below.

EXAMPLE 1

1st process

2 kg of salt is added to 100 kg of household sewage sludge (containing 60% water content) and dissolved by mixing, dissolving 200 g of potassium permanganate in 500 ml of water, and mixing 2 kg of ferrous sulfate into the domestic sewage sludge.

2nd process

20kg of lung paper is pulverized and mixed in a grinder with a blade to make powder.

3rd process

The first process material and the material of the second process are mixed and mixed.

4th process

1 kg of ammonium chloride is dissolved in 1500 ml of water, and 500 ml of croissant oil is prepared.

5th process

The flame retardant and the flavourant of the fourth step are mixed and mixed in the third step.

6th process

The waste sludge and the waste paper powder of the fifth process are completely mixed so that the waste paper powder is completely spread.

7th process

Prepare a building material template to be made by the present invention. The template prepared a brick template.

8th process

The material of a 6th process is put into the mold of a 7th process, and is extruded.

9th process

Prepare the dryer.

10th process

The built-in brick of the present invention, which is extruded in the eighth step, is placed in a dryer of the ninth step and completely dried in 200c rows to complete the product of the present invention.

Building sewage using sewage sludge and waste paper according to the present invention as described above is light and has a warming and filling effect, such as Schiropol not only has excellent thermal insulation effect and does not cause environmental pollution. Schiropol, which is widely used at present, is not biodegradable, so it rots well on the ground, causing environmental pollution, and in addition to causing large-scale agents such as poisonous sesame seeds, it regulates its use. In addition, the product of the present invention is effective in solving the problems of domestic sewage when used as a building interior and insulation.
