Description

Detailed Description of the Invention (Purpose) This invention uses the permeability of soil to diffuse rainwater, sewage, or liquid fertilizer into the soil, improves groundwater conservation, purifies soil 2N by soil microorganisms, and protects plant roots. It concerns methods of water treatment in the soil, such as fertilization.

Microbial contact materials such as stones, rubble, and plastic materials were piled up in an approximately triangular shape on an arc-shaped pelvis laid supine at the bottom of a trench dug on the ground surface, and a waxy water pipe was installed at the top. ,
A method for treating rainwater, sewage, or liquid fertilizer in which the water pipe and the contact body are covered with a net and filled with a permeable material on both sides is patented by the present application, the inventor, and the applicant. No. 126128
As is known from No. 6, if air can be supplied to the permeable material and the soil in contact with the outside thereof, and the outside of the treatment facility can be kept in an aerobic state, the patented invention will further extend the treatment capacity. be able to. The purpose of this application is to obtain a method for treating sewage, etc. that further increases the effects of the patented invention.

(Structure) Next, the structure of the embodiment of the present invention will be explained based on the drawings.
The figure is a side sectional view of the present invention. In the case of Figure 1, the receiver (
3) is placed on the bottom of the groove, but in Fig. 12, that is, in the present invention, J (2) is dug a little deeper and a ventilation material (8) such as coarse sand is placed at the bottom of the groove. A diffuser pipe (10) having a large number of diffuser holes (9) is installed inside the vent material. The air diffuser holes (9) can be opened in two rows above the air diffuser pipe (10) ('4pf') so that air is blown out obliquely upward. (Fig. 3) A gap for ventilation is provided between the pelvis and the groove wall, a contact body (4) is stacked on the pelvis, and a waxy water pipe (5) is passed over it. Cover the contact body and the water pipe together with a fine mesh net (6) from above, fill the space between the net and the trench wall with water absorption ↑O (7), and reach the top of the water absorption material to the ground surface; The construction is completed by filling it back up and connecting one end of the diffuser pipe (10) to the blower (11). The eighth function of the present invention starts by sending rainwater, sewage, or liquid fertilizer into a water pipe, and operating a blower to send air into an aeration pipe.

(Effects) Wastewater treatment in soil utilizes the organic matter decomposition action of microorganisms, and the patented invention has been highly evaluated as a trench system based on this principle. From the viewpoint of improving the patented invention, the present invention involves installing an aeration pipe using an aeration material such as coarse sand at the bottom of the trench, and aiming for the most aerobic range (dotted line in Figure 2). This system forcibly introduces air into the soil (inside the circle), thereby improving the capillarity of the soil and making the area aerobic, increasing the activity of microorganisms.

Claims (1)

[Claims] An arc-shaped receiver is placed face up at the bottom of a trench dug on the ground surface.
The microbial contact bodies are piled up in a roughly triangular shape on top of the receiving plate, a waxy water pipe is placed on top of them, the water pipe and the contact body are covered with a net, both sides are filled with permeable material, and the upper part is covered with soil. In a method for treating rainwater, sewage, or liquid fertilizer, a gap is provided between the receiving plate and the groove bottom, and an aeration material such as coarse sand is filled in the aeration material, and an aeration pipe having a large number of aeration holes is installed in the aeration material. 1. A method for treating rainwater, sewage or liquid fertilizer in soil, which comprises installing a pipe and connecting the end to a blower to flow the liquid to be treated through the water pipe and blowing air to the aeration pipe.
