が広がり農作物の被害も多発している。<Prior Art> The treatment of large amounts of polluted wastewater from washing commercial vehicles such as taxis and buses, or the treatment of wastewater from car washes of vehicles such as trains, has become a problem. Furthermore, car wash wastewater at gas stations is also a problem. The wastewater after a car wash is contaminated with impurities such as various detergents and oils such as wax, and the damage caused by this carwash wastewater is considered a pollution problem. In particular, there have been cases in which river fish have been frequently damaged by contaminating rivers, and recently, contamination has spread to agricultural irrigation water, causing frequent damage to agricultural crops.

、現実には、水質汚濁防止法による法令の許容限度の基
準を無視して放流しているのが実情である。Car wash wastewater has a high concentration of pollution and a large amount of contaminated water, so it is necessary to take measures immediately. However, since the conventional pumping equipment for gas stations takes only one hour and requires high maintenance costs (running costs), in reality, water is discharged ignoring the legal standards of permissible limits under the Water Pollution Control Act. That is the reality.

ではなかった。On the other hand, despite calls for water conservation, the amount of water used for car washing is increasing, and the water fees paid for this purpose are also increasing. Therefore, purification and reuse of wastewater is being considered, but car wash wastewater is highly polluted, so conventional devices cannot filter it sufficiently, and the filters in filtration devices need to be replaced frequently. Yes, it wasn't very practical.

The structure allows for backwashing even with fresh water. Although the shape of the filtration chamber is not limited as in the case of the filtration tank, in this embodiment, a cylindrical tank made of steel plate is used, and the inner wall thereof is coated with a corrosion-resistant coating. In addition, the ceramic filtration agent filled inside uses 1 existing ceramic filtration agent, and in this example, a filter core made of porous ceramic made of diatomaceous earth is fused and bonded, and a filter core is A ceramic filter agent is used, which consists of a silica gel coating formed by treating the outer periphery with ethyl silicate diluted with ethyl alcohol. This ceramic filter agent is porous and polygonal, and its specific gravity is 1/2 that of ordinary filter sand. Therefore.

濾過率の低かった洗車排水をスピーディにしかも充分に
濾過することが可能となった。濾過機にセラミック°濾

理された排水を水質汚濁防止基準法の許容限度に保つこ
とが容易に出来る利点がある。It became possible to quickly and sufficiently filter car wash wastewater, which had a low filtration rate. Because the filter uses a ceramic filter agent, it has a structure that allows for easy backwashing, which has the advantage of making it easy to maintain treated wastewater within the allowable limits of the Water Pollution Prevention Standards Act.
また１処理水を洗車用水として再利用することも可能で
あり、公害防止装置であると共に節水かつ省資源型の装
置である。Furthermore, it is also possible to reuse the treated water as water for car washing, making it a pollution prevention device as well as a water and resource saving device.
