The air bubbles are cut into smaller air bubbles after encountering the modified polypropylene coil in the rising process, the rising speed is delayed, at the moment, the modified fiber carrier can adsorb more oxygen, the retention time of air in water is obviously prolonged, the oxygen storage function is achieved, and the adsorption capacity is high.

Description

Technical Field

[0001] The utility model relates to the field of water treatment, in particular to a water treatment filler for efficient bio-enrichment. Background Art

[0002] In existing sewage treatment and river management projects, a wide variety of fillers are used, including fixed fillers, elastic fillers, combined fillers, etc. These traditional fillers often have various problems such as weak adsorption capacity, poor treatment effect, and complex installation.

[0003] In existing sewage treatment and river management projects, a wide variety of fillers are used, including fixed fillers and suspended fillers. Suspended fillers include soft fillers, semi-soft fillers, and combined fillers, each of which has its own advantages and disadvantages. For example, fixed fillers are characterized by stable treatment effects, but their specific surface area is not high and their cost is relatively high. Soft fillers are easy to form and remove films and have a large specific surface area, but when the concentration of organic matter in the wastewater is high, the filler fibers are prone to agglomeration and the filler ropes are prone to breakage. Semi-soft fillers have high porosity and low flow resistance, and are not prone to entanglement or clogging, but they are difficult to form films and have little sludge reduction. They are generally used for small-scale sewage treatment. Combined fillers are developed based on soft fillers and semi-soft fillers, and to a certain extent, they combine the advantages of both, but are relatively expensive. Utility Model Content

[0004] The purpose of the utility model is to provide a water treatment filler for efficient bio-enrichment.

[0005] The innovation of this utility model lies in that the filler in this patent is woven from three modified polypropylene materials. Since the filler is a columnar filler, it has a larger contact area with the activated sludge in water, and the skeleton modified polypropylene coil on the filler is relatively strong, which has a good "cutting effect" on water flow and bubbles, so that the bubbles are cut into smaller bubbles after encountering the modified polypropylene coil during the rising process, slowing down the rising speed. At this time, the modified fiber carrier can absorb more oxygen, significantly increasing the residence time of air in water, having oxygen storage function and strong adsorption capacity.

[0006] In order to achieve the above-mentioned utility model purpose, the technical solution of the utility model is:

[0007] A water treatment filler for efficient bio-enrichment comprises a filler body, wherein the filler body comprises a modified polypropylene middle rope, and the modified polypropylene middle rope is surrounded by a modified fiber carrier and a plurality of modified polypropylene coils.

[0008] Furthermore, the modified fiber carrier and the modified polypropylene coil are woven on the modified polypropylene middle rope to ensure a firm connection.

[0009] Furthermore, the diameter of the filler body is 50-60 mm. The cylindrical filler of 50-60 mm has a large relative area in water.

[0010] Furthermore, the modified fiber carrier is composed of modified polypropylene elastic yarn, which has good hydrophilicity.

[0011] Furthermore, the diameter of the modified polypropylene elastic wire is 2000D. The 2000D elastic wire has a good effect on capturing sludge and is easy to form biofilm quickly.

[0012] Furthermore, the circumference of the modified polypropylene coil is 80 mm. After being enclosed, the modified polypropylene coil with a circumference of 80 mm is substantially the same width as the modified fiber carrier.

[0013] Furthermore, the modified polypropylene coils have a diameter of 0.3 mm and are evenly spaced along the circumference and length of the modified polypropylene intermediate rope. The modified polypropylene coils are spaced 3.3 mm in the lengthwise direction of the modified polypropylene intermediate rope. The evenly spaced modified polypropylene coils form a skeleton, increasing the stability of the entire packing structure.

[0014] The beneficial effects of the utility model are:

[0015] 1. The columnar filler in this utility model increases the contact area between the filler and the activated sludge in water, allowing the filler to form biofilm quickly and evenly. Due to the "cutting" effect of the filler skeleton on the bubbles, more oxygen is trapped at the lower end of the filler, forming a dissolved oxygen gradient from bottom to top on the filler, greatly improving the denitrification and phosphorus removal effects. Due to the existence of the dissolved oxygen gradient, aerobic and anoxic layers coexist on the filler. In the aerobic layer, ammonia nitrogen is oxidized to nitrate nitrogen, while nitrification, denitrification, and anaerobic ammoniation oxidation occur simultaneously in the anoxic layer, forming N microscopic A2 / O processes, while the total nitrogen and organic matter in the water are efficiently treated.

[0016] 2. In the utility model, the filler is entirely attached to the modified fiber carrier and has a high down content.

[0017] 3. The filler in this utility model is easy to install, does not require steel support, has a long service life and low installation cost.

[0018] 4. The filler in this utility model is suitable for different environments, and can be used in aerobic, anaerobic, facultative aerobic, river management, etc. BRIEF DESCRIPTION OF THE DRAWINGS
