Description

[Detailed explanation of the invention] "Industrial application field" This invention relates to wastewater filters for households, factories, etc.

``Conventional technology'' Traditionally, in areas without sewage systems, wastewater from households and school lunch factories is discharged, which pollutes gutters and streams, causing the murmuring streams of the past to disappear. In addition, various ideas have been devised to address the decline in functionality due to clogging of materials in conventional overtanks for factories, but in rural areas and local cities where there is no sewerage system, it is difficult to easily recover from the decline in functionality due to clogging, scale, etc. Because of the heat, wastewater filters could not become widespread.

``Problems to be solved by the invention'' This invention is designed to easily obtain a filter that improves overfunction and easily restores overfunction when treating wastewater from school cafeterias and households in areas without sewage facilities. This is what we are trying to do.

``Means for solving the problem'' This proposal connects a first tank to the bottom of a wastewater storage tank that has an upper end above the ground, and connects the bottom of the first tank to the bottom of a second tank that has an upper end above the ground. The bottom part is connected underground, and an overwater discharge port is provided at the top of the second overtank.
The waste water filter is constructed by removably fitting a material cartridge into both of the filter tanks.

``Function'' Therefore, when wastewater is induced and stored in the storage tank, the wastewater passes downward through the material cartridge in the first filter tank at the bottom, passes upward through the material cartridge in the second filter tank from the connection part, and is filtered. Then, it is discharged into the side gutter etc. from the discharge port located at the upper part of the second tank. The material in the cartridge becomes clogged after a certain period of time and loses its functionality, but before it is lost, the cartridge is pulled out onto the ground 8 and replaced with a new one.

"Example" The middle part of the large-diameter wastewater storage tank 1 is buried in the ground 8,
A small-diameter first overtank 2 is connected to the hopper-shaped bottom of the same tank 1 in a funnel shape, and a second overtank 3 having the same diameter as that of the same overtank 2 is connected to the hopper-shaped bottom of the same overtank 1.
are buried at approximately the same level, and the bottoms of both tanks 2 and 3 are connected 4 with a connecting pipe 4' to communicate with each other. Second
The upper part of the overflow tank 3 is made to protrude slightly from the ground 8, and an overwater discharge port 5 toward the side ditch is provided in the buried part of the upper part. The upper ends of the wastewater storage tank 1 and the second tank 3 are opened and closed with lids 9 and 10. Then, the material cartridges 6 and 7 are fitted into the first storage tank 2 and the second storage tank 3 through these openings, and inside the storage tank 1, the upper end opening is lined with a filter 11 such as felt at the bottom. A tank 12 is supported, a coarse waste collection net 13 is suspended above the inner tank 12, and a waste water pipe 14 is opened above the opening. A semiconductor layer 15 for ionization, a carbon layer 16 for adsorption, an aluminum oxide layer 17 for pH adjustment, and a carbon layer 18 for adsorption are laminated from above on the material cartridge 6 of the first tank 2.
The material cartridge 3 of the second tank 3 includes, from below, an adsorption carbon layer 19, an aluminum oxide layer 20 for pH adjustment, a semiconductor layer 21 for ionization, and an adsorption carbon layer 22.
are stacked, and the discharge port 5 is provided thereon. 23 in the figure is a stop filter in the material cartridges 6 and 7, 24 is a connection plate between the storage tank 1 and the second filter tank 3, 25 is a support frame for the collection net 13,
26 is a support protrusion of the inner tank 12, and 27 is a deodorizing vent pipe provided on the lid 9.

``Effects'' Since the present invention is constructed as described above, it can be installed very easily in regions without sewage systems, and not only can wastewater be purified, but also the material cartridges 6 and 7 can be quickly replaced with new ones to prevent overperformance. It can be easily handled and environmental pollution caused by wastewater can be prevented.
