Problems solved by technology

[0003] The treatment of sewage by biological filters depends on the fillers. In the process of filler preparation, some microorganisms in the fillers multiply when they contact sewage due to incomplete sterilization, causing secondary pollution to sewage and affecting the purification effect of sewage.

Abstract

The invention discloses a bactericide used for a biofilter filler and a preparation method of the bactericide, and relates to the field of bactericides. The bactericide is composed of the following raw materials in parts by weight: 50-70 parts of resina liquidambaris, 30-40 parts of cortex meliae, 15-25 parts of chenopodium ambrosioides, 30-50 parts of fruits of perilla frutescens, 15-35 parts ofchalcanthite, 12-15 parts of copper hydroxide, 4-6 parts of papain, 1-2 parts of kasugamycin, 15-35 parts of potassium dichromate, 8-10 parts of potassium iodate, 18-22 parts of sodium dodecyl benzenesulfonate, 1-2 parts of trimethoprim, 700-800 parts of deionized water, and 100-120 parts of glycerin. The prepared bactericide disclosed by the invention can damage harmful bacteria of the filler inthe process of synthesizing the filler, so that the prepared filler has a high sterile degree and does not cause secondary pollution to water bodies.

Description

Technical field: [0001] The invention relates to the field of fungicides, in particular to a fungicide used for biological filter tank fillers and a preparation method thereof. Background technique: [0002] The biological filter is a biological treatment structure composed of crushed stone or plastic product packing. The sewage is in contact with the microbial film growing on the surface of the packing to purify the sewage. The advantages of the biological filter are: 1) The treatment effect is very good, and it can meet the most stringent environmental protection requirements in any season. 2) No secondary pollution will be produced. 3) Microorganisms can grow on the organic matter in the filler without adding additional nutrients. Therefore, the startup speed is fast after shutdown, and the best treatment effect can be achieved immediately after shutdown on weekends or after 1 to 2 weeks of shutdown, and the best treatment effect can be achieved after a few hours. Stop...
