Description
Technical field
The present invention relates to wastewater from car washer to handle recovery technology field, and in particular to a kind of ECFF (electric flocculation EC+ electrofloatation
EF+ filters AF) type integration electric flocculation carwash waste water processing unit and treatment process.
Background technique
The excess exploitation of growth, the expanding economy and resource of population, very big pressure is caused to environment: water resource is tight
Lack again, water pollution is increasingly sharpened.With the improvement of people's living standards, unit and family-owned automobile quantity are also increasingly
More, this certainly will bring a large amount of consumption of car wash water, for city, then more exacerbate the contradiction of shortage of water resources.According to statistics,
Water 0.06-0.10m need to be used by cleaning 1 kart3, the water of 1 big and medium-sized cities 1 year for carwash then makes for 60,000 populations
With 1 year, the consumption of car washing water was seen some from this.
Further, since specification is also owed to the management of car wash trade in many cities, the random discharge of car wash water causes sewage to flow over,
Seriously affect the appearance of the city and civic living environment.It is a large amount of containing oils, organic matter, anion synthetic detergent etc. in wastewater from car washer
Polluter, with regard to direct emission, certainly will pollute water body as without processing.
Great lot of water resources to be expended for wastewater from car washer and pollutes the status of environment, corresponding limitation has been made in some cities,
Such as Beijing, Tianjin, Shijiazhuang." Harbin City city save water regulations " regulation, with water time limit car washing water in short supply,
Water-saving device should be installed by managing the entity and individual such as bathing, carwash.In recent years, once multiple seasonality forbids using clear water for Harbin City
Carwash.Some cities control carwash water consumption with economic means also by high water price method.
As it can be seen that saving car washing water, reducing carwash water pollution is urgent problem, and the processing of wastewater from car washer with
Reuse is the inexorable trend of development.
