The system comprises a reclaimed water treatment tower and an air purification device. The whole filtering and washing processes are controlled automatically through a programmable logic controller (PLC) control system, the degree of automation in the treatment process is greatly improved, addition of chemical cleaning agents and the existing manual cleaning mode are changed, possibility of secondary pollution is avoided, treated water is used for dust removal by ventilation for air in some special occasions such as underground passages, underground garages, basements of large buildings and subways, recycling of water is achieved, surplus water can be used for usage of surrounding waterscapes and cleaning.
Description
Technical field
The invention belongs to water-air Combined Treatment technology, relate to a kind of general sanitary sewage water body can be processed to higher water quality more than the middle water and in order to air in the preliminary purification special space device and method.
Background technology
Along with the rapid propelling of Re-search on Urbanization and the significantly raising of living standards of the people, so that a large amount of subways, underground garage and underpass are built up, they are distributed in biotope, megastore, office building, bustling highway section etc.Air is usually relatively more dirty in this space-like, contain a large amount of former, inhalable particles and heavy metals of causing a disease, serious harm people healthy, consider that this space-like flow of personnel is frequent, the characteristics that residence time is short are developed and are a kind ofly invested little, easy to operate, effective removing dust by using fresh air system and have important practical significance.
Sanitary wastewater storage in the city is very big, lets alone to flow directly into sewer very unfortunate.China is a country that drought and water shortage is serious, the freshwater resources total amount is 28000 billion cubic meters, account for 6% of global water resources, only have per capita 2200 cubic metres, only be world average level 1/4, the U.S. 1/5, ranking 121 in the world, is one of 13 countries that water resource is the poorest per capita in the whole world.Therefore under the prerequisite of water of advocating thriftiness, the removing dust by using fresh air system that the sanitary wastewater reuse is combined with air cleaning meets the energy-conserving and environment-protective theory.
Chinese patent 200620018407 discloses a kind of fresh air ventilator, and housing is arranged, breeze fan, exhaust fan, low efficient filter, heat exchanger and control system etc.The electrostatic dust-collecting device, oxygen enrichment generating means and the negative ion generating device that link to each other with control system difference electricity also are housed in the housing, can better remove the following pellet of 1 μ m removes, but various control assembly does not embody energy-conservation requirement, the new wind quality of having selected excessive demand of some devices, cost of investment is too high, and inappositely iron, underground garage and underpass; Chinese patent 200810121619 discloses a kind of fresh air purifier, adopts electrostatic dust absorption device and ultraviolet ray sterilizing device to combine, and when guaranteeing the room ventilation ventilation, purifies air and kills virus.Its simplicity of design is taken up an area littlely, basic only consuming the energy and keep the operation of VMC, fails to embody energy conservation characteristic.By inspection information, existing VMC patent does not almost make water purify, and especially relates to the air cleaning of above-mentioned several special spaces.
Summary of the invention
Technical problem to be solved by this invention is, provides that a kind of apparatus structure is reasonable, easy to maintenance, environmental friendliness and be convenient to realize the automatically removing dust by using fresh air device and method of control.
