Attapulgite circulating water sterilizing algicide

Abstract

The invention discloses an attapulgite circulating water sterilizing algicide which comprises acidized paste attapulgite clay, chlorine dioxide, lauryl dimethyl benzyl ammonium chloride, 2,2-dibromo-2-nitrilo-propionamide, siloxane emulsion and deionized water. The ingredients of the attapulgite circulating water sterilizing algicide are added into a stirred for low-speed stirring, input into a multifunctional colloid mill after being stirred and mixed uniformly for grinding into a paste mixture, and canned into the finished product of the attapulgite circulating water sterilizing algicide. The attapulgite circulating water sterilizing algicide has good adhesive force, can kill bacteria, fungus, moulds, alga and the like in industrial circulating water without generating pesticide resistance, has the functions of absorbing oil stains and removing peculiar smell as well as releasing corrosion and inhibiting scale, has long effective time of killing the bacteria and the alga without accumulated toxicity, is not influenced by water hardness, can be naturally degraded without causing the environment pollution, and is suitable for killing the bacteria and the alga of the circulating water.

Description

technical field [0001] The invention relates to a bactericidal algicide, in particular to an attapulgite circulating water bactericidal algaecide. Background technique [0002] In the open circulating cooling water system, the hazards of microorganisms, bacteria, and algae are often listed as the three major hazards together with the hazards of scale and corrosion. The environment of the circulating cooling water system provides excellent conditions for the reproduction of microorganisms. The large number of microorganisms in the circulating water system will make the cooling water black and smelly, polluting the environment, and will form a large amount of slime to reduce the cooling efficiency of the tower. , If the slime is deposited in the heat exchanger, the heat transfer efficiency will decrease rapidly and the water pressure loss will increase; the slime deposited on the metal surface will cause serious corrosion under the scale. In the circulating water system, due ...

Problems solved by technology

If no sterilization treatment is carried out, even if the microorganisms do not grow and reproduce, as the concentration increases, the number of microorganisms will increase exponentially, which will pose a direct threat to safety, economy and stable operation

[0003] Some bactericidal and algae-killing measures have been taken in some circulating cooling water systems, but due to the use of a single bactericide, the bactericidal effect is relatively poor
