Problems solved by technology

However, the disadvantage of this patent is that when the biological particle bed is used as the biological carrier, the biological carrier particles must be precipitated or filtered during the discharge stage, and then the biological carrier particles must be sent back to the biological pool, so the treatment process is relatively complicated
Because the carrier used in this patent is in the form of a foam, the available porosity range is between 30% and 100%. Although it has more pores, it is prone to the phenomenon that it cannot sink into water, so it must be Additional hydrophilic treatment must be carried out in the porous carrier to allow the carrier to sink into the water smoothly
Because the preparation method of the porous carrier is still too complicated, it is easy to limit its application range
[0007] In view of the shortcomings of the existing biological carrier, such as the complicated production process and the inability to exert purification efficiency, if the biological carrier with the advantages of simple production and high purification efficiency can be used in the fluid purification method and system, the problem of environmental pollution will be effectively improved. And for the current industry, there is still a huge demand

Embodiment 1

[0059] [Example 1] Production of a block-shaped nonwoven fabric having a central anchor line

[0060] Using polypropylene / polyethylene core-sheath composite fiber (manufactured by Taiwan Far East Textile Co., Ltd., product name SP-2650EP, fiber fineness of 6 denier, length of 5.1 cm) as raw material, this composite fiber was opened, cleaned After cotton, carding and stacking are processed, a fiber web layer is formed, and then the fiber web layer is subjected to the first fixing treatment of needle rolling and hot air processing, so that the fibers in the fiber web layer form a three-dimensional space bond to form a fibrous web layer. Nonwoven rolls with a basis weight of 500 kg / m² and a width of 1.8 m. The non-woven roll is then cut into a non-woven roll with a width of 0.6 meters, and then the non-woven roll is transported in the machine direction (that is, the longitudinal direction of the non-woven roll), and is subjected to a second fixing treatment The ultrasonic bondin...

Embodiment 2

[0061] [Example 2] Wastewater purification system using the block nonwoven fabric of Example 1

[0062] like Figure 12 As shown, the wastewater purification system 4 is a system for treating wastewater, and the wastewater purification system 4 includes a tank body 41 for containing wastewater and a volume of 500 liters, placed in the tank body 41 and obtained by the Example 1. A block-shaped nonwoven fabric 42 having a central anchor line, a spacer 43 and two diffusers 44. The tank body 41 has a waste water outlet 411 and a waste water inlet 412 opposite to and staggered from the waste water outlet 411 . The isolation device 43 is disposed in the tank body 41 and close to the waste water inlet 412, and is composed of a porous plate body. The two diffusing devices 44 are respectively disposed on both sides of the tank body 41 and have a plurality of holes 441 for gas to escape, so that the block-shaped non-woven fabric 42 can be fully mixed with the waste water.

Embodiment 3

[0068] [Example 3] Wastewater purification system using activated sludge-grown bulk nonwoven fabric

[0069] The block non-woven fabric obtained in Example 1 was subjected to the following activated sludge planting process: collecting the sludge in the waste water recovery tank of the laundry factory, this sludge is the so-called "activated sludge", and then the sludge was collected. The sludge and an appropriate amount of water are put into the treatment tank, and then the block non-woven fabric of Example 1 in the amount to be used is put into the treatment tank for about 8 hours to obtain the activated sludge planted block-shaped nonwoven fabric. spinning.

[0070] Utilize the wastewater purification system of Example 2, and purify according to the same method of Example 2, but replace the block nonwoven fabric 42 of Example 2 with the block nonwoven fabric planted by activated sludge, Finally, after the same 12 hours, water samples were taken at the inlet and outlet of th...

Abstract

The purification method for polluted fluid is to put multiple block fiber aggregates into the target and contact to purify the fluid. Wherein, the aggregate can be non-woven fabrics, bunch fiber, puff fiber, textile fabric or packaging pouch. The corresponding purification system comprises a tank to accommodate the sewage and multiple fiber aggregates.

Description

technical field [0001] The present invention relates to a method for purifying contaminated fluid and its use, in particular to a method for purifying the contaminated fluid by using a plurality of aggregates of bulk fibers that move in a fixed manner or along with the contaminated fluid, and in addition , also relates to a contaminated fluid purification system, a preparation method of a biological carrier suitable for treating the contaminated fluid, and a non-woven biological carrier prepared by the preparation method. Background technique [0002] The existing treatment methods of contaminated fluids (such as waste water or waste gas) are mostly carried out by chemical or physical treatment methods, such as using filtration or adding chemicals. In addition, there are many methods of treating fluids by means of microbial decomposition. Since it is difficult to control the number and survival time of microorganisms, in actual use, most of them will provide an environment ...
