Description
Technical field
The utility model relates to the rural potable water processing technology field, relates in particular to a kind of rain collecting cellar water quality purifying device for water with biological slow filter.
Background technology
NORTHWEST CHINA arid area surface water resources scarcity, ground water aquifer is darker, and some no groundwater resource in area can utilize, and villages and small towns regions resources lack of water is serious, especially in the Northwest's surface water and the extreme Drought Mountain Area that lacks of underground water, rainwater is unique potential water resources.The rainfall in rainy season is collected and is stored in the effective way that has become solution northwest drought water-deficient area water shortage problem in the water cellar as the daily life tap water.But, because rainwater is subjected to solid waste chip (rubbish, animal excrement etc.), air bells laid thing, chemical fertilizer, agricultural chemicals, vehicle emission and other pollution that is brought by mankind's activity in collection process.In addition, rainwater causes aqueous metamorphism, spoiled in the medium-term and long-term storage of water cellar, directly drinks and can produce very big harm to people and animals.Investigation finds that microorganism, organism, total nitrogen etc. often exceed standard in the water, and colourity and turbidity are relatively poor, and the pollutent that exceeds standard mainly comprises bacterium, intestinal bacteria, colourity, turbidity, heavy metal etc.; Polycyclic aromatic hydrocarbons, phthalate etc. aspect organic micro-pollutants, have been detected.And at present domestic most cleaner all is at cleaner relatively city planting ductwork feedwater and as the rivers and lakes water of drinking water source, specifically at collection rainwater water quality, is fit to the small-sized collection rainwater purification device that the northwest village distributing uses and yet there are no report.
At present, biological activated carbon technology in water treatment field has the effect of good removal organism, ammonia nitrogen and colourity, effect is not good enough on sterilization and control heavy metal, and polynary micro electrolysis tech does not almost have removal effect to organism, but in replacing water heavy metal and germ-resistant aspect good effect is arranged.In addition, existing micro-polluted water treatment facility great majority all need the professional to operate debugging, personnel's educational level on scattered settlement ground, northwest village is generally lower, the level that does not also possess the such equipment of operation, and level of automation height, the easy equipment of operation adopt electric autocontrol system price costliness more, and northwest village population does not mostly also possess the condition of buying such equipment.
Under this background, remain to be researched and developed a kind of simple to operation, special at the water treatment device of handling this special micro-polluted water.
