JP3023208U - Hanging basket for filth purification - Google Patents

Abstract

(57) [Summary] [Challenge] Due to changes in the living environment, the amount of disinfection, sterilization, and use of detergents on foods has increased, making it difficult to spontaneously decompose sewage, making it a difficult problem to solve. The purpose of the present invention is to quickly decompose and digest the source of anaerobic malodor emitted from filth to easily and effectively maintain its efficacy for a long period of time at low cost. SOLUTION: This is a product in which a mixture of waste dehydrated sludge at the end-of-life treatment plant heated and dried and shellfish is packed in a porous basket and suspended in a sewage tank that produces a bad odor.

Description

[Detailed description of the device] [Industrial applications]

 The present invention relates to elimination of anaerobic malodor generated from waste by eliminating organic matter in waste at high speed by utilizing residual bacteria in terminal sludge.

[Prior art]

 Most of the sludge at the terminal treatment plant is dumped into the ocean or incinerated.

[Means for solving the problem]

 The present invention is easy to dispose of, and does not require facilities such as auxiliary machines to eliminate and eliminate the source of bad odor over a long period of time.

[Means for Solving the Problems]

 Heated and dried dehydrated sludge from the terminal treatment plant and shellfish are mixed in an appropriate ratio of about 1: 3, packed in a porous basket, and suspended and immersed in the waste tank.

[Action]

 Bacteria that survive in the heated dry matter of the terminal sludge are activated by the water content of the wastewater.The organic matter in the wastewater is rapidly decomposed and digested without aeration at room temperature, and the anaerobic odor disappears in a short time, and the tank is removed at the time of pumping. Most of the inside is filled with dirty water. Even after the pumping, even if the bacteria live in the shell and dry, the activity is repeated due to the inflowing waste, and the effect continues for a long time.

[Effect of device]

 As a result of implementing the present invention, the properties of urine were greatly improved, and the residual values of BOD, COD, SS, phosphorus, Escherichia coli, etc. were extremely reduced. In addition, since scum cannot be completely formed on the upper surface of the filth, no harmful insects are generated inside or outside the tank, and there is almost no strong bad odor due to the exhaust sulfide gas of the vacuum car that occurs when collecting human waste, thus improving the working environment. Is significant, and the life of the equipment is significantly extended due to the reduction of sulfide gas and ammonia gas. Therefore, the effect of contributing to waste utilization and environmental improvement is great.

【Example】

An example of the present invention will be described. Table 1 shows the properties of general human waste. A hanging basket in which 200 g of dried sludge per 1 m ³ was mixed in a 1 m ³ waste tank and a 30 m ³ waste tank was hung as shown in FIG. 4 and the urine properties were measured after 3 weeks. As a result, to obtain a shown to properties in Table 3 for Table 2,30M ³ waste tank for waste bath 1 m ^3.
