Outside equipment waste water odor is more and more common, walking on the side of the road can smell the smell of sewage wastewater! Sometimes the tap water we use at home will also have odor, this time can not be used directly, must be treated before use. So what are the harms caused by the odor of wastewater? Specific hazards are as follows:

· It will affect respiratory function, thereby reducing digestive function;

1.mental irritability, low work efficiency, poor judgment and memory;

2.Living and living in a malodorous environment for a long time can cause olfactory disorders and damage the central nervous system;

3.excitatory and regulatory functions of the cerebral cortex;

· Some aquatic products can not be eaten or sold because of the odor;

· The malodorous water body can not swim, can not raise fish, drink, destroy the use and value of water;

· It will also produce toxic hazards such as hydrogen sulfide and formaldehyde.

Acid and alkali pollution changes the pH of the water body to destroy the buffering effect, eliminate or inhibit the growth of microorganisms, hinder the self-purification of the water body, and can also corrode Bridges, ships, and fishing gear. Acid and alkali enter the same water body at the same time, can produce neutralized salts, from the point of view of pH value, acid and alkali pollution through the neutralization of self-cleaning, producing a variety of salts, which has become a new pollutant in the water body. The increase of inorganic salt can increase the osmotic pressure of water, which has a bad effect on the growth of freshwater organisms and plants, and the salt in salinized areas, surface water and groundwater also harms the quality of soil.

In fact, if you want to use healthy water resources, water quality online monitoring work is also essential, in addition, in this simple introduction of domestic wastewater, industrial wastewater main monitoring projects are what: chemical oxygen demand COD, biochemical oxygen demand BOD, suspended matter, total bacteria and so on. As for the detection of these projects to use the water quality monitor is not a single, according to the specific parameters of the corresponding monitoring instrument!
