Description

Manure grinding and sterilization device using electrolysis device {SEWAGE TREATMENT DEVICE HAVING GRINDING AND STERILZING APPARATUS BY ELECTROLYSIS}

The present application relates to a manure treatment device, and illustratively relates to a marine pollution prevention facility that can be mounted on a ship and treated to meet environmental standards before discharge of manure to the sea, and more specifically, to efficiently grind manure in a narrow space. And an apparatus for performing disinfection.

As the Convention on the Prevention of Sewage, which regulates the discharge of sewage from the toilets of ships, has entered into force internationally, various international standards and related laws are being maintained. These laws and regulations establish standards according to the type, weight, or number of ships on board, and according to the standards, sewage generated from ships is, for example, treated in a sewage treatment system similar to a septic tank facility on land, and then discharged or discharged. It is stored in the water and then discharged from the receiving facility on land, and the discharge of pollutants from the sea is prohibited at all.

In general, as a method of treating manure or sewage, a physical treatment method using a membrane, a biological treatment method using microorganisms, a chemical method using a disinfectant, an optical method using UV or plasma, or an electrolysis method using an electrolysis reaction, etc. There are various treatment methods, but in the facility of a device for applying these various methods, it must be applied in consideration of the specificity of a ship. In other words, it is easy to install in very narrow places such as ships, the maintenance and installation costs are low, and while it is possible to have facilities that are easy to replace with existing ships, it contributes to the conservation of the marine environment by satisfying various legal regulations. You should be able to do it.

In this regard, Korean Patent Laid-Open Publication No. 2010-0003819 relates to a'ship manure and sewage filtration treatment device (hereinafter referred to as'prior technology 1')', and in detail, it is applied to contaminated water flowing through the contaminated water inlet. A crushing dehydrator attached to one side of the rectangular cylindrical body to crush and dehydrate contained impurities and suspended matter, a first cylindrical body inscribed with the inner wall of the rectangular cylindrical body when viewed from above, and a first cylindrical body inside the first cylindrical body. 1 by a second cylindrical body concentrically arranged with the cylindrical body, a third cylindrical body concentrically arranged with the second cylindrical body inside the second cylindrical body, and the first and second cylindrical bodies. A first biofiltration reaction tank formed in a compartment, a second biofiltration reaction tank formed by the second and third cylinders, and a third biofiltration reaction tank formed inside the third cylindrical body, wherein the A dehydration injection chamber is partitioned by a corner portion of the first biofiltration reactor and the square cylinder on the side of the crushing dehydrator, and the second and third biofiltration reactors are defined from the bottom of the square cylinder in the first biofiltration reactor. A first communication port is arranged so that the storage chamber in the first biofiltration reactor and the dewatering injection chamber communicate with each other in the first biofiltration reactor on the side of the dehydration injection chamber, and It presents a technology that is configured to be opened.

As in the prior art 1, a combination of biological treatment and chemical treatment, including physical methods such as gravity separation and filter filtration, is mainly used in ships. However, the situation in which the criteria for verifying total inflow and total outflow have been added to the performance test items of the manure treatment device installed on the ship recently, or the situation in which the total nitrogen and total phosphorus measurement items of the manure treatment system installed in passenger ships operating in the Baltic Sea have been added. If considered, there is a problem that it is difficult to properly treat the manure treatment of ships using microorganisms due to fluctuations in the load of organic substances, and in particular, the need for an additional device for advanced treatment for the removal of nutrients such as nitrogen and phosphorus, and the ship There is a problem that I cannot install in my narrow space.

In addition, a device for treating manure through a physical method and a chemical treatment method may be provided without excluding a biological treatment device, and the related manure grinding and disinfection device artificially injects drugs into the manure storage tank, or a separate drug storage tank.
