and intrusion of seawater intrusion in coastal areas. Salt water intrusion refers to sea water intrusion of freshwater aquifers phenomenon. The main cause of sea salt water intrusion is the excessive exploitation of ground water fresh water. my countrys northern coastal region, into 80 years, consecutive years of drought, low rainfall, reducing groundwater recharge, but industrial and agricultural water consumption has to be increased, fresh groundwater "make ends meet", resulting in seawater intrusion.
Industrial "waste" (waste water, waste) is a major factor groundwater contamination. Industrial waste such as industrial wastewater, industrial pickling sewage, industrial waste smelting, light industry and petrochemical wastewater without organic wastewater treatment and municipal sewers, rivers and lakes or directly into the ditch, big seepage pit, resulting in groundwater chemistry Pollution.
due to the agricultural activities caused by groundwater pollution sources include soil residual pesticides, fertilizers, animal and plant remains decomposition and irrational sewage irrigation. They cause a large area of 鈥嬧€媠hallow underground water quality deterioration, the most important is the pollution of pesticides and fertilizers.
economy continues to develop, a lot of plastic, metal, batteries and other indigestible new garbage appeared, one side is the basisLack of facilities and control, rural sewage, garbage straight row phenomenon is more serious.

using the water purifier, the water can filter impurities the drinking water standard drink reach, and lower cost. Water purifier filter used is a purely physical way, can effectively remove various types of impurities in water, such as bacteria, chlorine, heavy metals, scale (calcium and magnesium, etc.), volatile substances, rust, sand and the like.
