Description

[Detailed Description of the Invention] (Industrial field of application) The present invention relates to an apparatus for purifying sewage from domestic wastewater separated from human sewage wastewater, which has been improved to improve efficiency in terms of function and space. Is.

(Prior Art) In recent years, sewage due to so-called miscellaneous wastewater, such as cooking, washing, bathing, and washing, of domestic wastewater is being separated from human waste water and treated separately. The amount of wastewater from domestic wastewater is so large that it occupies most of the total amount of domestic wastewater compared to the amount of wastewater. Furthermore, since the domestic wastewater has different pollutant components from human wastewater, it should be treated separately. The wastewater discharged as a conventional means for treating wastewater from domestic wastewater has been directly sent to the purification treatment tank consisting of each treatment chamber which has a sedimentation filtration separation function for purification treatment. It was

(Problems to be solved by the invention) As described above, the conventional household wastewater sewage treatment apparatus has a configuration in which household wastewater contaminated by various detergents is directly introduced into a purification treatment tank composed of a plurality of treatment chambers for treatment. Therefore, from the recent domestic wastewater volume, which is said to be about 250 per person per day, a large space is required due to the large capacity of the septic tank to obtain a high degree of purification accuracy. In the treatment mechanism using only the purification treatment tank that acts, the inflowing sewage flows directly through the wastewater supernatant of the treatment process in each chamber of the purification treatment tank due to the flow of the large amount of household wastewater that has been directly discharged and inflowed, resulting in poor purification efficiency. From that,
A large capacity septic tank was required, and the installation space was further increased.

In addition, a mechanism that intervenes a device for performing preliminary treatment between the drain pipe and the septic tank has been tried, but all of these pretreatment devices rely only on natural advection due to the height difference between the inlet and outlet. Since it is an advection system, excessive advection occurs, and although a complicated flow rate adjusting device for adjusting this is provided, it is a complicated device in which delicate flow rate adjustment is difficult to operate.

This invention improves the purification treatment mechanism of these household wastewater treatment equipment so that the flow rate of wastewater in the wastewater treatment process can be easily fine-tuned and the flow efficiency is introduced to improve the treatment capacity. The purpose is to greatly improve the size of the processing apparatus, so that the installation space can be reduced by making the processing apparatus as small as possible.

(Means for Solving the Problems) In order to achieve the above-mentioned object, the present invention provides a treatment device that communicates with a drainage pipe for household wastewater such as homes and accommodation facilities, including a first adjustment tank, a second adjustment tank, and a purification treatment. The first adjustment tank, which is composed of tanks and communicates with the drainage pipe, is divided into a retention adjustment chamber that can communicate with the drainage pipe with a vertically-divided partition and a contact aeration adjustment chamber that is equipped with contact members and is equipped with an air diffuser. The second adjustment tank, which is connected to the bottom of the first adjustment tank by the communication pipe arranged at the bottom, operates the blower in the contact aeration adjustment chamber of the first adjustment tank to activate the second adjustment tank. In order to send air and water with an air lift and to circulate it to the contact aeration adjusting chamber of the first adjusting tank with an overflow pipe, the purification treatment tank is placed below the second adjusting tank, and is separated into front and rear separation chambers. The contact aeration chamber and the filtration chamber are configured separately to increase the flow of sewage to each chamber. Introduced from the vicinity of the edge to the vicinity of the bottom, settled in the separation chamber, contact aerated by the air diffuser pipe in the contact member spread in the contact aeration chamber, and successively formed to filter through the filter material spread in the filtration chamber, This is to propose a domestic household wastewater treatment device, characterized in that the bottom of the second adjustment tank is connected to the vicinity of the upper edge of the purification tank via an adjustment valve. First, which is placed vertically between and to send air and water,
With an adjusting tank consisting of a second adjusting tank interposed, the sewage sent to the first adjusting tank is actively separated and forcedly sent to the second upper adjusting tank, and the difference in height and the flow rate to the purification tank by the adjusting valve. It makes it easier to send water while finely adjusting the flow rate, and in addition to the configuration that the flow of sewage in each chamber is sequentially introduced from the upper edge to the bottom in the purification tank, the separation and purification action of sewage in the purification tank Worked efficiently and succeeded in reducing the installation space on the plane of the entire processing equipment.

(Operation) While vertically arranging the first and second adjusting tanks between the drainage pipe and the purification treatment tank, the sent domestic wastewater is aerated and aerated in the first adjusting tank for active separation, Since the sewage that has been purified to some extent is sent to the upper second adjustment tank, the advection using the height difference from the second adjustment tank to the purification treatment tank and the fine adjustment of the flow rate by the adjustment valve are clogged with hydrophobic contaminants. It can be fed smoothly and accurately with fine adjustment without blocking.

In the first adjusting tank, the supernatant part of the sewage that has precipitated in the retention adjusting chamber is made to flow into the contact aeration adjusting chamber, and deodorized by contacting the air by air diffusion, and the pollutants are deodorized and attached to the contact member to be activated. , The purified wastewater is forcibly sent to the upper second adjusting tank, and the excess water is returned to the first adjusting tank by an overflow pipe and circulated.

In the septic tank, sewage is introduced into the adjacent treatment chambers from the top edge to the bottom and then flows into and out of the treatment chamber. Completely purified fresh water by contacting with air diffuser and sending the purified rising portion to the filtration chamber while adhering and separating the contaminants to the contact member, and further passing through the filtration medium during the rising process in the filtration chamber. Will be discharged. As described above, the actions of precipitation separation, contact aeration, and filtration work efficiently together with the inflow and outflow from the upper side and the deposition filtration processing mechanism of each chamber utilizing the ascending action.
