Embodiment 1

[0052] Sewer: According to the size of the sewer pipe diameter, put in a suitable floating pad. The floating pad floats in the pipe and also floats with the sewage in the pipe. The floating pad floats in the pipe to eliminate the internal larvae. At the same time, the adsorbent can More than 400 kinds of chemical substances such as aromatic hydrocarbons, alkanes, and alcohols in the pipeline are adsorbed, and the oil stains washed down by rain can be cleaned while killing mosquitoes; it can be recycled at the drain of the sewer pipeline. Realize the complete killing of mosquito larvae in sewage drainage pipes and sewer pipes, and at the same time, achieve unexpected technical effects in purifying water quality.

Embodiment 2

[0054] Open-air ponds in the suburbs of cities, polluted ponds, and fish-free stinky ditches, because pesticides and other chemical preparations cannot be used in these places, a large amount of Bt preparations are used for spraying treatment before traditional methods, but this requires a lot of human resources to spray At the same time, the efficacy of the spray in water is not high, and it needs to be re-sprayed every other time, which wastes a lot of manpower and is not efficient. Using the Bti floating pad of the present invention, a pack of 20 square centimeters can prevent and treat 50 to 100 square meters In the water area, only one person needs to manually place the floating pad in one place. The floating pad will float with the water flow, and effectively kill mosquitoes in the water area that floats through, and remove the aromatic hydrocarbons, alkanes, and Alcohols and more than 400 kinds of toxic chemicals.

Embodiment 3

[0056] Water shortage areas such as tap water towers and reservoirs need to save and utilize drinking water sources, and because water towers and reservoirs need to store water all year round, it is easy to breed mosquito larvae and inevitably have peculiar smells. It can eliminate the internal larvae, and at the same time, it can also adsorb and remove toxic chemicals such as alkanes, benzenes, and aldehydes in the water. Long-lasting results can be achieved by replacing the flotation pad while in use. Thereby play the unexpected technical effect of efficiently killing mosquitoes and purifying drinking water.

Abstract

The present invention relates to the technical field of sanitary and epidemic prevention biology, and particularly relates to a Bacillus thuringiensis subsp. Israelensis floating pad capable of killing wiggler in water and removing toxic chemical substances from sewage. The Bacillus thuringiensis subsp. Israelensis floating pad comprises an adsorbent capable of adsorbing aromatic hydrocarbon-base chemical solvents, wherein the adsorbent is packaged by a pad bag, comprises a chemical composition containing a Bacillus thuringiensis subsp. Israelensis fermentation broth extract chemical component Bti, and can adsorb toxic chemical substances in sewage, the chemical composition can be directly used through the pad bag packaging so as to save labor by 90%, the appearance shape of the pad bag is a wave shape to expand the contact surface between the pad bag and the water surface and improve the slow release effect so as to improve the efficacy by 98% and prolong the shelf life, and the floating pad cannot be eaten by organisms in river, cannot pollute water ecosystem, is suitable for the mosquito prevention and control of drinking water sources, can provide unique anti-mosquito effect, can effectively adsorb and clear toxic chemical substance from sewage, and can achieve the double effect of mosquito killing and water purification.

Description

technical field [0001] The invention belongs to the technical field of sanitation and epidemic prevention, in particular to a Bacillus thuringiensis subsp. Background technique [0002] Mosquito larvae, also known as larvae, like to breed in shallow water within 3-5 cm from the water surface, and then breed into adults, spreading diseases and endangering humans. Eliminating mosquito larvae that breed in water and reducing the incidence of adult mosquitoes in cities and rural areas have always been the main tasks of health and epidemic prevention departments. The traditional mainstream method of eradicating mosquito larvae is to use chemical insecticides, biological agents and ecological control techniques only play an auxiliary role. In recent years, due to the increasing awareness of environmental protection, starting from the need for water source protection, national regulations and public voices have all required the prohibition, restriction, and reduction of chemical p...
