Abstract

PROBLEM TO BE SOLVED: To provide a sewage cleaning device which is used for treatment of industrial waste water, domestic waste water, drainage, waste water from agricultural colonies, livestock waste water, rivers, lakes, marshes, etc., and has a high performance to be suitable for cleaning treatment of various kinds of sewage by eliminating disadvantages of a conventional device and is reduced in production cost. SOLUTION: Cylindrical bodies 1 which are bent into an arbitrary wavy form as the whole by narrow wire rods made of a synthetic resin are connected to poles, which are arranged in upper and lower parts in parallel at equal intervals, to constitute an organism contact member 4, and these organism contact members are set in many arrays so that each of cylindrical bodies constituting each member may be shifted from respective cylindrical bodies of adjacent members, and many arrays of organism contact members constituted in this manner are laid on a peripheral attaching frame body 5 through the poles.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sewage purification apparatus, and its use is for treating industrial wastewater, domestic wastewater, sewage, agricultural settlement drainage, livestock sewage, rivers and lakes, and the like.

[0002]

2. Description of the Related Art Conventionally, a contact material made of a PVC plate having a three-dimensional honeycomb-shaped corrugated structure has been used for sewage treatment for the above-mentioned applications, but it has the following disadvantages in terms of performance and cost. there were.

[0003] First, in terms of performance, PVC boards do not have air permeability, so that sewage from the horizontal direction is difficult to contact, and sewage flowing in from the vertical direction adheres aerobic bacteria to the middle part of the contact plate. It was difficult, and as a result, the sewage treatment capacity of the entire apparatus was extremely low.

Second, in terms of cost, since the product itself constituting the entire apparatus cannot be assembled and manufactured on site by bonding or the like, the weight is relatively light, but the air transport is required, and the transport cost is high. Since a frame to be fixed at the site had to be manufactured, a construction cost had to be obtained by asking a specialized construction contractor for the installation work.

[0005]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a high-performance and low-cost apparatus suitable for purifying various kinds of sewage, which has eliminated such disadvantages of the conventional apparatus. Is what you do.

[0006]

SUMMARY OF THE INVENTION According to the present invention, a cylindrical body, which is entirely formed by bending an arbitrary wave shape with a thin wire made of synthetic resin, is connected to rods arranged at upper and lower portions in parallel at equal intervals. A biological contacting member is constituted, and the biological contacting members thus constituted are arranged in a large number of rows, and each cylindrical body constituting each member is installed so as to be inconsistent with each adjacent cylindrical body of the same member. A large number of rows of the biological contact members described above are constructed on the surrounding mounting frame via the rods.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION The above-described apparatus is installed at a predetermined sewage treatment site, and the length of a cylindrical body constituting a biological contact member is previously formed in accordance with the situation at the site. The intervals can be freely changed in advance.

[0008] Since aerobic bacteria are adhered to the biological contact material and cultured, the larger the surface area of the fixed reef, the more effective and the higher the treatment capacity.

In normal times, only a part of the air diffuser installed below the group of biological contact members is blown by using a part of the blower by operating a valve, but aerobic bacteria adhere to the biological contact member too much. When the air blower is operated, the air diffuser is fully opened by operating all the air blowers to blow the air in a concentrated manner, and the aerobic bacteria are separated from the biological contact member by the strong wind.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference numeral 1 denotes a cylindrical body formed by forming a synthetic resin thin wire into a hollow cylindrical shape by three-dimensionally bending it into an arbitrary wave shape. A wire is inserted into the core of the synthetic resin thin wire. Good.

Reference numeral 2 denotes a rod, which has the cylindrical body 1
And the bridge 3 are alternately inserted to form a biological contact member 4 formed by connecting a number of cylindrical bodies in parallel at equal intervals.

The installation interval between the cylindrical body 1 and the wheel 3 on the rod 2 constituting each of the biological contact members 4 is set at a position that is inconsistent with each other at a ratio of 1 to 1 for the reason described later. Prepare.

Reference numeral 5 denotes a rectangular mounting frame, and the right and left ends of the rod 2 of the biological contact member 4 are mounted between the left and right frame members 6 and 6 of the mounting frame. This attachment means is detachable by screwing.

A large number of biological contact members 4 are attached to the mounting frame 5.
In order to ensure that adjacent cylindrical bodies 1 do not touch each other when they are mounted and that they have an efficient operation, the cylindrical bodies are arranged so as to maintain mutually inconsistent positional intervals.

In the embodiment, the size of the mounting frame 5 installed in water is, for example, 2 m in length and width, and a gantry 7 is installed around a lower portion of the mounting frame.

Reference numeral 8 denotes an air diffuser installed below the mounting frame 5 by piping. The air diffuser is a utility model registration No. 2095536 (Japanese Utility Model 7-1) according to the same applicant's invention.
1837). In this case, if a negative ion generator is installed and used, it becomes more effective.

[0017]

According to the apparatus of the present invention, the inflow and outflow of sewage from any direction can be performed at any place of use, and a large number of cylindrical bodies constituting each biological contact member can be used. Since the area where bacteria are attached is extremely large, the sewage treatment capacity is dramatically increased, and the treatment and construction costs thereof are relatively inexpensive.
