Embodiment 1

[0060] Dissolve four kinds of lactone group-sensing inhibitors (m-bromothiolactone, m-chlorothiolactone, chlorothiolactone, and chlorolactone) in a small amount of distilled water to prepare a 10 ppm solution.

[0061] A small amount of municipal sewage was taken, and the total bacterial concentration was measured to be 9.7*10 9CFU / mL. Municipal sewage was filtered with qualitative filter paper, placed in a biofilm formation assay reactor, and the biofilm thickness was measured after 12 hours. Dosing 10mg of medicament in 1L of municipal sewage

Embodiment 2

[0066] Dissolve four bromofuranone quorum-sense inhibitors in a small amount of distilled water to prepare a 10 ppm solution.

[0067] A small amount of municipal sewage was taken, and the total concentration of bacteria was measured to be 9.2*10 9 CFU / mL. Municipal sewage was filtered with qualitative filter paper, placed in a biofilm formation assay reactor, and the biofilm thickness was measured after 12 hours. Dosing 10mg of medicament in 1L of municipal sewage

Embodiment 3

[0073] according to figure 1 The formula and preparation process shown: First, weigh 15 kg of sodium lauryl sulfate and 15 kg of anhydrous sodium bicarbonate, put them into a mixer and stir evenly to prepare a composite solubilizer.

[0074] Then 13.3kg of m-bromothiolactone, 13.3kg of brominated furanone and 13.3kg of AIP compound were weighed and put into a blender to stir evenly to prepare a composite quorum sensing inhibitor.

[0075] Put above-mentioned compound solubilizing agent, compound quorum sensing inhibitor and dodecylguanidine hydrochloride 30kg into the blender and mix and stir evenly, after stirring for more than 30 minutes, sieve with a sieve more than 200 mesh, filter out larger particles, and It is compressed into tablet form.

[0076] The stirring time required to prepare a solution with a concentration of 10ppm is 1 minute

Abstract

The invention discloses a medicine for alleviating municipal sewage pipeline blocking and application of the medicine. The medicine is prepared from the following components in percentage by mass: 20-40% of a quorum sensing inhibitor, 30-50% of a surfactant and 20-30% of a solubilizer, wherein the quorum sensing inhibitor consists of the following components mixed in percentage by mass: 40-60% of meta-bromo-thiolactone, 20-30% of bromination furanone and 10-30% of AIP compounds. The quorum sensing inhibitor is taken as a main component, the quorum sensing behavior of microorganisms in a sewage pipeline can be inhibited, and thus the microorganisms can be prevented from forming biological membranes to block the sewage pipeline.

Description

technical field [0001] The invention relates to the field of municipal sewage transportation, in particular to the preparation and application of a medicament for slowing down the clogging of municipal pipelines. Background technique [0002] In recent years, with the rapid development of urban construction, urban drainage facilities have also become an important basic project for the construction and development of modern cities, and are essential infrastructure for ensuring the production and life of citizens. Although my country's urban drainage facilities are constantly improving, siltation and blockage of municipal drainage pipes are still relatively common phenomena. In many places, silt accumulation and blockage of drainage pipes have occurred, resulting in overflow of sewage and water on roads, which not only pollutes the environment but also hinders traffic, bringing a lot of inconvenience to residents. Therefore, how to prevent the silting and clogging of municipa...
