Because the temperature of circulating cooling water is very suitable for the growth of bacteria and microorganisms, and the bacteria and the microorganisms in the water body are quickly propagated by the full irradiation of sunlight, the microorganisms can be metabolized in the water to generate slime, the slime is attached to the surface of heat exchange equipment to reduce the heat exchange efficiency, and scale is generated to corrode and damage the equipment, and chemical medicines such as bactericide and the like can be added into the water body when the bacteria and algae are serious, so that the environmental protection and the negative influence on workers are caused.
The prior treatment modes are time-consuming and labor-consuming compared with the technical scheme, and the economical efficiency is obviously insufficient.

In order to achieve the purpose, the invention adopts the following technical scheme:
a new noise reduction and bacteriostasis method for a cooling tower is characterized in that sufficient high-density polyethylene vacuum plastic balls which can fully cover the surface of a water pool and float on the water surface are put into water in a cooling tower pool, the high-density polyethylene vacuum plastic balls are impact-resistant, sound-absorbing and noncorrosive, the impact direction of water drops falling can be changed due to the mellow surface characteristics of the balls, and the sound generated when the water drops flap on the water surface is reduced to reduce the water spraying noise of the cooling tower; and the high-density polyethylene vacuum plastic balls cover the surface of the water body, can absorb the heat energy of the sun, isolate the sun from irradiating microorganisms in water, shield the photosynthesis of the microorganisms, block the biosynthesis chain of the microorganisms and the bacteria and the algae, enable the microorganisms and the bacteria and the algae not to reproduce, and play a role in inhibiting the reproduction of the bacteria and the algae.
In order to prevent the high-density polyethylene vacuum plastic balls from being washed away by running water, filter screens are additionally arranged at a sewage discharge port and a high-level overflow port of the circulating cooling water system, the aperture of each filter screen only allows the water to flow, the high-density polyethylene vacuum plastic balls and sundries in the water are intercepted by the filter screens, the high-density polyethylene vacuum plastic balls and the sundries are prevented from blocking a water channel, and the circulating cooling water system is protected safely.
The size of the high-density polyethylene vacuum plastic ball is made into the same or different sizes according to the scale and the structure of the cooling tower, or the sizes are mixed and matched according to a preset proportion for use as long as the high-density polyethylene vacuum plastic ball can float on the water surface and can be tightly close to each other.
In order to improve the light absorption performance of the high-density polyethylene vacuum plastic ball, the high-density polyethylene vacuum plastic ball is black.
The method is simple, the aim can be achieved by only putting a sufficient amount of high-density polyethylene vacuum plastic balls into the water tank, in order to prevent the polyethylene balls from being carried away by flowing water, filter screens are additionally arranged at a sewage discharge port and an overflow port of a circulating cooling water system, the aperture of each filter screen only allows the water to flow through, and the polyethylene balls and sundries in the water are intercepted by the filter screens, so that the balls and the sundries are prevented from blocking the water channel, and the system is protected safely.
