Problems solved by technology

[0005] Although all kinds of adsorption and separation materials have made important research progress, their practical progress is relatively slow. In the treatment of some water pollution, a large number of materials have not been practically constructed, and are directly dumped into sewage for adsorption. The efficient utilization and recovery of adsorbent material

Embodiment 1

[0032] see Figure 1~6, a combined sewage treatment device, including a sewage filter assembly, a large number of micropores that allow water molecules to pass through are distributed on the sewage filter assembly, and the sewage filter assembly is arranged along the direction of cutting water flow; the sewage filter assembly separates the sewage treatment pool into The sump 1 and the clarifier 2, the sump 1 is used to collect the sewage to be treated, and the clarifier 2 is used to temporarily store the treated purified water; the sewage filter assembly is assembled and connected by a plurality of sewage treatment element boards 7, Each sewage treatment unit plate 7 has a unit frame 3, and the outer edge of the unit frame 3 is provided with a connecting part 6, and each unit frame 3 is movably assembled with the adjacent unit frame 3 through its connecting part 6 to form an integral network Grid-shaped sewage filter assembly, the shape and size of the outer contour of the sew...

Embodiment 2

[0042] see Figure 7 , this embodiment is basically the same as the first embodiment of the present invention, the difference is:

[0043] Adjacent unit frames 3 in the present invention are connected by hinges 10 in a hinged manner, and folded and unfolded by fan blades to realize the retraction of a plurality of sewage treatment element plates 7; the unit frames 3 are installed on one side close to the top surface There is a fixed locking hook 8 connecting the buoy 9.

[0044] For oil spill accidents in lake waters, the sewage treatment device of the present invention can remove a large area of ​​oil floating on the lake surface. Such as Figure 7 As shown, the sewage treatment unit frame 3 structure made of engineering plastic ABS is selected. The length of the rectangular unit frame 3 structure is 2m, the height is 1m, and the thickness is 20cm. Adjacent unit frames 3 are hingedly connected by hinges 10, folded and unfolded by fan blades to realize the retraction and st...

Embodiment 3

[0046] This embodiment is basically the same as the first and second embodiments of the present invention, the difference is that:

[0047] In the laboratory pool, a small amount of benzene solvents often flow in. The sewage treatment device of the present invention can purify the laboratory wastewater and can absorb the benzene solvents therein. Install the miniaturized sewage treatment device of the present invention in the sewer pipe of the pool, select the cylindrical unit frame 3 structure of copper material, the cylinder radius is 5cm, long 30cm, it is connected to the drainage pipe. Activated carbon is selected as the water treatment adsorbent 5, and the activated carbon is filled into the net cage formed by the movable assembly of the cylindrical unit frame 3 and the cover plate 4, and is stored in the unit frame 3 structure with the cover plate 4 made of copper mesh to prevent its drain. Laboratory wastewater enters from one side of the cylindrical sewage treatment u...

Abstract

The invention discloses a combined type sewage treatment apparatus, which comprises an integrated grid-shaped sewage filter component formed through assembled connection of a plurality of sewage treatment primitive boards. The outer contour of the filter component is adapted to the shape and the size of a cross-section of flowing water of the sewage so as to determine the shapes and the number ofthe selected sewage treatment primitive boards. Each sewage treatment primitive board comprises a cage for filling with a water treatment adsorbent, wherein a unit frame and two cover plates with meshes are actively assembled into the cage. With the meshes in the cover plate, the water treatment adsorbent in the cage can be prevented from loss. The shapes and the number of the sewage treatment primitive boards can be adjusted freely, such that the size of the sewage treatment apparatus can be adapted to a sewage treatment system requiring treatment. The sewage treatment primitive boards are easy to be disassembled and assembled, such that the water treatment adsorbent can be reused so as to reduce the secondary pollution. The apparatus provided by the present invention has characteristicsof simple structure, convenient operation, low cost, strong applicability and good size adjustability, and can be applicable for various sewage treatment systems.

Description

technical field [0001] The invention relates to a sewage treatment device, in particular to a combined sewage treatment device which is convenient for disassembly and assembly, and belongs to the technical field of industrial and domestic waste water treatment. Background technique [0002] In recent years, my country's water pollution accidents have occurred frequently. In November 2005, the Songhua River was polluted by nitrobenzene; in December 2005, an explosion occurred in the Dianjiang River in Chongqing City, which caused the leakage of benzene series, causing Xinmin Guixi River, Caojia River, etc. River pollution; at the end of 2005 and early 2006, cadmium pollution occurred in the Beijiang River of Guangdong and the Xiangjiang River of Hunan Province; at the end of May 2007, a blue-green algae crisis broke out in Taihu Lake. In 2005, the National People's Congress Standing Committee's Water Pollution Prevention and Control Law Enforcement Inspection Team found that a...
