Although car washing is still mainly manual in most of domestic car service stores, the intelligent car model has been developed at an accelerated speed. In foreign countries, the intelligent car washer belongs to a popular car washing mode and is distributed in life service areas. Domestic car washers mainly cover specific places such as gas stations, 4S shops at present, lack the application scene of liveness.

The intelligent car washer cannot cover in a large scale, so that application scenes are lacked, and the method mainly comprises two aspects; on the one hand, the price of the equipment and on the other hand, the treatment of the wastewater; the main reason is the subsequent treatment of the wastewater. Although the equipment cost is low, the labor cost is high; although the intelligent car washer is high in equipment price, a large amount of labor cost is saved.

Because the efficiency of manual service car washing in stores is generally low, the number of cars washed every day is not too large, and the amount of generated waste water is not too large; most of the waste water generated by car washing in stores is basically discharged to a municipal sewage pipe network, and the waste water from car washing and other common domestic sewage are discharged to a sewage treatment plant together by the municipal sewage pipe network for indiscriminate treatment.

The number of the intelligent car washer for washing the car per day can be increased by times or even tens of times, and the amount of the generated car washing waste water is increased correspondingly; therefore, the waste water can not be directly discharged into the urban sewage pipe network, and can be discharged into the sewage pipe network only after the waste water is pretreated to reach the standard.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

Referring to fig. 1 to 18, as an embodiment of the present invention, the wastewater treatment circulation system for an intelligent car washer includes a cabin 1 with a top and a bottom through, wherein the cabin 1 is used as a square cabin of the wastewater treatment circulation, and has the same shape as a container, or can be directly formed by transforming a waste container;

the specific transformation mode is that the tail door of the container is welded, and then the bottom and the top of the container are cut to be communicated up and down; the reutilization of abandonment container can be realized, and the transformation degree of difficulty is less, and it is with low costs to reform transform. Of course, the shelter 1 of this construction can be produced directly for use.

The ground beams 60 with equal height are arranged at the bottom of the inner wall of the cabin body 1, the number of the ground beams 60 is four, the ground beams are connected end to end and are arranged at the bottom of the cabin body 1 through bolts, so that a skid-mounted base is formed, and the installation and the disassembly are convenient.

The system is still including installing grid processing cabin 6, flocculation cabin 7, aeration cabin 8 and circulation cabin 9 in the cabin body 1, above-mentioned four cabins distribute in cabin body 1 along the length direction of the cabin body 1 in proper order, and the bottom in four cabins all is installed through the bolt on the sled dress base.

The grid treatment cabin 6, the flocculation cabin 7, the aeration cabin 8 and the circulation cabin 9 are communicated with each other; specifically, the bottom of the grid treatment cabin 6 is communicated with the upper part of the flocculation cabin 7, the bottom of the flocculation cabin 7 is communicated with the upper part of the aeration cabin 8, the bottom of the aeration cabin 8 is communicated with the upper part of the circulation cabin 9, and the middle position of the circulation cabin 9 is communicated with the bottom of the grid treatment cabin 6; the four parts form the circulation communication between the cabin and the cabin so as to circularly and circularly treat the waste water.

Wherein, a lifting type grating structure is arranged in the grating treatment cabin 6 and is used for removing larger suspended matters in the wastewater from the grating treatment cabin 6 in a lifting and dumping mode; as a large amount of sundries including soil, straws in the soil, dead branches and fallen leaves, stones and the like are attached to the car body to be cleaned, the sundries are mixed in the waste water generated by car washing, and the sundries including the straws, the dead branches and fallen leaves, the stones and the like can be separated through the grid treatment cabin 6.

Three medicine boxes 23 are suspended above the flocculation cabin 7, and a coagulant, a magnetic seed and a coagulant aid are respectively placed in the three medicine boxes 23; the wastewater with larger suspended matters separated by the lifting type grid structure is discharged into the flocculation cabin 7, and the medicines in the three medicine boxes 23 are respectively thrown into the flocculation cabin 7 according to the sequence of firstly throwing the coagulant, then throwing the magnetic seeds and finally throwing the coagulant aid;

in detail, the action mechanism of the wastewater and the coagulant is as follows: the small suspended colloid and dispersed particle in waste water are made to produce floccule under the mutual action of molecular force and to collide with each other for coagulation in the deposition process, and this results in ever increased size and mass and raised deposition speed.

The mechanism of action with the magnetic species is as follows: magnetic substances or weak magnetic substances in the wastewater are combined with magnetic seeds to increase the specific surface area, and are attached to a floccule with a larger volume to form a magnetic floccule; is beneficial to reducing the substances such as chroma, turbidity and the like of the wastewater.

Since many vehicle body members are steel or iron, oxides (for example, rust) on the surface of the vehicle body are detached during washing, and a small amount of ferromagnetic substances are contained in the wastewater; the magnetic substances in the wastewater can be separated by the arranged magnetic seeds.

The sewage demagnetizing technology is widely applied to the treatment of wastewater in the steel industry such as steel hot rolling, continuous casting wastewater, cold rolling emulsion and the like; different from the invention, because the proportion of the strong Magnetic wastewater in the wastewater generated in the steel-making and iron-making industry can reach 98 percent, the invention needs to be matched with a High Gradient Magnetic separation technology (HGMS technology), namely a Kolm-Marston type modern High Gradient Magnetic Separator (High Gradient Magnetic Separator) which is formed by combining a steel wool type miniature Magnetic gathering medium and an iron armor coil; the wastewater in the invention has extremely low content of strong magnetic substances, so that a small amount of strong magnetic substances can be removed only by adding magnetic seeds.

Finally, the coagulant aid is put in the wastewater, so that a small amount of incompletely condensed impurities and medicines still exist in the liquid wastewater after most suspended substance colloids, dispersed particles and magnetic substances in the wastewater form magnetic flocs; at the moment, the coagulant aid is put into the flocculation cabin 7, so that the combination of unreacted medicines and uncondensed impurities in the liquid wastewater can be improved, on one hand, the action efficiency of the medicines can be improved, and the wastewater is prevented from containing a large amount of unreacted medicines; on the other hand, the content of colloid, particles and magnetic substances in the wastewater can be further reduced.

The bottom of the aeration chamber 8 is provided with an air distribution disc 59, the aeration chamber 8 is also internally provided with a filter frame 57, the filter frame 57 is arranged above the air distribution disc 59, and after wastewater enters the aeration chamber 8, the magnetic flocs are separated from the liquid wastewater through the filter frame 57; the air distribution plate 59 forcibly transfers oxygen in the air from the bottom of the aeration tank 8 to the separated liquid wastewater, so that the dissolved oxygen amount of the wastewater is increased, and organic matters in the wastewater are oxidized and decomposed.

Finally, the wastewater enters the circulation cabin 9 for sedimentation, the sedimentation objects mainly include impurities which have larger mass and cannot form floccules, such as gravel and the like, and the sediments have larger mass and relatively stably stay at the bottom of the circulation cabin 9 to be separated from the wastewater;

thereby completing a full cycle of processing.

Then the wastewater in the circulating cabin 9 enters the grid treatment cabin 6 again to be treated for a second period, so that circulating purification is realized; because the middle position of the circulation cabin 9 is communicated with the bottom of the grid treatment cabin 6, impurities precipitated at the bottom of the circulation cabin 9 cannot enter the grid treatment cabin 6.

In addition, since the wastewater in the circulation tank 9 is already the wastewater treated by the elevating type grid structure, it is not necessary to elevate it to the upper portion of the grid treatment tank 6; but only needs to be sent to the bottom of the grid treatment chamber 6 to be sent to the flocculation chamber 7 for secondary dosing.
