Description

Technical Field

[0001] The invention relates to the technical field of pond sewage treatment, in particular to a method for preparing suspended biowax with accurate control of the specific gravity of the biowax and a formula thereof. Background Art

[0002] Biowax is a substance with a special microcapillary structure. The microcapillaries inside it provide an ideal environment for beneficial bacteria to attach and survive, promoting the growth of beneficial bacteria in water and inhibiting the reproduction of harmful microorganisms. Biowax technology can effectively decompose organic matter, oil and other pollutants in wastewater, improve the clarity of water quality, reduce the content of pollutants such as total phosphorus and ammonia nitrogen, and has no chemical additives. The use of biowax is not limited to sewage treatment, but also involves the construction of water ecology and other fields. As a new type of water treatment material, biowax not only has extremely low toxicity, but also can effectively promote water purification. Its application prospects in the global market are very broad.

[0003] The existing bio-wax technology has the following shortcomings: (1) The matrix of bio-wax is high molecular weight hydrocarbons or high carbon alcohols such as paraffin and beeswax. The specific gravity of such substances is generally lighter than water, and they are easy to float on the water surface, which is not conducive to the reproduction of microorganisms. (2) The method of fixing bio-wax with ropes and sinking stones to the bottom of the water can solve the problem of bio-wax floating, but because it is fixed underwater, the contact range between bio-wax and water body is reduced, which is not conducive to the growth of biofilm and the purification of the entire water body. (3) The existing method is difficult to measure the true specific gravity or density of powder materials and irregular solids, so the specific gravity of bio-wax cannot be accurately controlled by specific gravity calculation. (4) The existing bio-wax technology lacks an ideal method for inserting bacteria. Summary of the invention

[0194]

[0195] Take this water as the experimental object and conduct water treatment experiment:

[0196] 10L of the water was taken and added to the fish tank, the water temperature was controlled at 25°C, the fish-shaped biowax of each embodiment and comparative example was placed in the fish pond, and the water was circulated for 7 days with a small fish pump. The biowax samples of the embodiments could float freely in the pond, and the biofilm formation was observed by comparing with the comparative example. The experimental results are shown in the following table.
