であることが望ましい。Conventional technology If sewage generated from corporate facilities or households is directly discharged to a river, the river will be polluted and the local environment will be deteriorated. Therefore, it is customary to purify these effluents with a purification device before discharging them. Is. In particular, in recent years, the improvement of rivers has progressed and the self-cleaning action of rivers has weakened, and along with the population increase in the river basin and economic development, pollution of water quality has become a problem. Therefore, it is desirable that the purification device not only purifies the wastewater but also promotes the self-cleaning action of the river after the discharge.

Then, the oil content in the wastewater is attached to the solid matter, and the floating oily solid matter is removed by the microscopic automatic screen installed in the rear channel of the oil content mixing tank and stored in the adjacent sludge storage tank and the oil solid matter is collected. After temporarily storing the oil mixing tank that allows the removed wastewater to flow into the raw water adjusting tank and the wastewater flowing from the oil mixing tank in the raw water adjusting tank, pump it to the adjusting pump installed in the raw water adjusting tank and use it for the measuring instrument. A raw water conditioning tank that feeds a fixed amount to the fluidized aeration tank, and a powder mainly composed of natural minerals that treats the wastewater sent from the raw water conditioning tank that circulates with the sewage and inhabits a group of tiny unicellular protozoa. Shaped or granular contact material From the contact aeration tank, which is filled with a fluidized aeration tank and a porous contact material mainly composed of natural minerals capable of inhabiting multicellular metazoans, and which is ejected from the diffuser pipe located below it. Crashes and circulates the inflowing wastewater to efficiently dissolve oxygen in bubbles and dissolve in the wastewater to attach single-celled protozoa, dead bodies, and untreated waste in the wastewater to the porous contact material mainly composed of natural minerals. It is filled with a contact aeration tank that is processed by multicellular metazoan and a predetermined contact body mainly composed of natural minerals, and a sprinkler pipe is arranged above it to flow in from the contact aeration tank. The treated water to be treated is evenly sprinkled, and by passing between the porous contact materials, the dead cells and pollutants of multicellular metazoans in the treated water are filtered, and nitrogen, phosphorus, etc. in the treatment are treated by microorganisms as biological treatment or porous. Removed by chemical action of contact material A purifying device comprising: a sprinkling filter tank, and the oil mixing tank according to claim 2, the raw water adjusting tank according to claim 3, and the fluidized aeration tank and contact aeration tank according to claim 4. According to claim 5, the sprinkler filtration tank is provided. Further, according to claim 6, when the porous contact material mainly composed of natural minerals is clogged in the sprinkling filter tank, the operation of the drainage pump is stopped to fill the inside of the sprinkling filter tank to a certain water level, and the porosity is increased. A structure for removing clogging between porous contact materials by diffusing air from an air diffusing pipe disposed below the contact material, according to claim 7, the treated water flowing from the contact aeration tank in the sprinkling filter tank is treated. The present invention provides a configuration in which the sludge is returned to the sludge storage tank, filtered by a water filter plate installed in the sludge storage tank, and returned to the raw water adjusting tank as wastewater.

ない。また、油分に依る浄化作用を妨げることがない。Action With such a sewage purification apparatus, the sewage flowing from the inflow pipe is removed to the sludge storage tank by the fine automatic screen provided in the water passage of the oil mixing tank. Then, the sewage that has passed through the fine automatic screen is sucked up by the adjusting pump installed in the raw water adjusting tank that is stored and flows into the raw water adjusting tank, and a fixed amount of sewage is supplied to the fluidized aeration tank by the measuring device. Therefore, a large amount of wastewater does not flow into the fluidized aeration tank as it is from the factory. Further, it does not interfere with the purifying action due to oil.

きに依って導入され接触曝気槽内へ流入する。Next, the sewage that has flowed into the fluidized aeration tank is pushed up by the pressure of bubbles ejected from the air diffuser arranged below the water passage together with the powdery or granular contact material that enables the inhabitation of tiny unicellular protozoa. By circulating the water through the water pipe and circulating in the fluidized aeration tank, it is possible to improve the efficiency of contacting the sewage with the organisms living in the contact material and improve the purification efficiency. In addition, the treated sewage rises from the bottom of the settling tank installed on the side of the fluidized aeration tank. At this time, the contact material settles and does not flow out, while the treated sewage and the separated protozoa and carcasses are introduced by the overflow and flow into the contact aeration tank.

る。In the contact aeration tank in the next stage, a porous contact material mainly composed of natural minerals is filled, and a diffusing pipe is arranged below and flows between the porous contact materials depending on the bubble pressure ejected from the diffusing pipe. The treated sewage is activated by the chemical action at the time of collision, enhances the efficiency of dissolved oxygen, promotes the activity of metazoans that require a large amount of oxygen in the sewage, and predatory action by the food chain On the basis of the above, the protozoa can be digested and untreated pollutants can be treated. In particular, in a sprinkler filtration tank, phosphorus that dissolves in the treated water when the porous contact material layer is evenly dropped from the sprinkling pipe contacts or permeates the porous contact material and causes magnesium oxide and carbon dioxide which are components of the porous contact material. It becomes a substance that does not dissolve in the treated water due to its chemical action with calcium, and is adsorbed and removed by the porous contact material. Nitrogen is treated as nitrogen gas depending on the microorganism group.
