With the continuous increase of the holding capacity of automobiles, the waste water amount generated in the automobile washing industry is also continuously increased, so that the problem of waste water treatment is increasingly outstanding. Because the vehicle is cleaned by using chemical substances such as organic cleaning agents, a large amount of greasy dirt, silt, chemical cleaning agents and the like are contained in the vehicle cleaning wastewater, and biomass harmful substances are bred in the vehicle cleaning wastewater in the conveying and storing processes; if the car washing wastewater is directly discharged into the environment, serious pollution is caused to the water body. Therefore, the car washing wastewater can be safely discharged after being purified.
When the current car washing wastewater is subjected to purification treatment, the current car washing wastewater is generally subjected to purification treatment in a pipeline treatment mode, namely the car washing wastewater is filtered, then corresponding medicaments are sequentially added according to the volume of the car washing wastewater to carry out the steps of suspended matter removal, organic matter removal and the like, then the purified car washing wastewater is subjected to water quality monitoring, and if various standards of the car washing wastewater meet requirements, the car washing wastewater is discharged, otherwise, the purification treatment is carried out again.
The step of purifying the car washing wastewater cannot carry out intelligent purification treatment according to the pollution condition of the car washing wastewater, so that the purification treatment efficiency of the car washing wastewater is lower, and the degree of the purification treatment cannot be monitored in real time in the process of purifying the car washing wastewater, so that the purification treatment is required to be carried out again when the emission monitoring of the car washing wastewater is not in accordance with the requirement, further the time cost of the car washing wastewater is increased, and the efficiency is reduced; the medicament added in the car washing wastewater is added according to the volume of the car washing wastewater, so that the medicament is wasted when the corresponding pollutants in the car washing wastewater are fewer, and the purification treatment requirement can not be met when the pollutants are more; in addition, the purification treatment efficiency of the car washing wastewater cannot be counted, so that the purification treatment of the car washing wastewater cannot be counted in a refined mode.

Referring to fig. 2, the determining manner of each treatment step of the car washing wastewater is as follows: and (3) reading the pollution index of the solid sundries, comparing the pollution index with the pollution index threshold of the solid sundries, and if the pollution index of the solid sundries is larger than the pollution index threshold of the solid sundries, filtering and impurity removing treatment steps are needed for the car washing wastewater, otherwise, the filtering and impurity removing treatment steps are not needed for the car washing wastewater. The filtering and impurity removing treatment step is used for filtering and removing solid impurities. The solid impurity pollution index threshold is an industry standard set value stored in the purification treatment database.
The pollution index of the foam floaters is read and compared with each threshold value interval of the pollution index of the foam floaters, the amount of the defoaming agent to be added is correspondingly arranged in each threshold value interval of the pollution index of the foam floaters, the threshold value interval of the pollution index of the foam floaters is determined through comparison, the amount of the defoaming agent to be added is further determined, foam floaters are conveniently subjected to defoaming treatment, the addition amount of the defoaming agent is in direct proportion to the value of each threshold value interval of the pollution index of the foam floaters, and the threshold value interval with the minimum pollution index of the foam floaters does not need to be added; similarly, the pollution index of the suspended matters is compared with each threshold interval of the corresponding pollution index of the suspended matters, so that the amount of the flocculant is determined, and the suspended matters are conveniently removed; the pollution index of the organic pollutants is compared with each threshold interval of the pollution index of the corresponding organic pollutants, so that the amount of the added biological reinforcing agent is determined, and the organic pollutant removing step is facilitated.

The analysis mode can clean up solid impurities in the car washing wastewater, so that the subsequent purification treatment step of the car washing wastewater is facilitated.
S2, after the foam floater defoaming treatment step of the car washing wastewater is finished, the volume of the foam floater on the car washing wastewater is obtained, the pollution index of the foam floater is obtained through analysis, if the pollution index of the foam floater is in a threshold value interval with the minimum pollution index of the foam floater, the suspension removing step is carried out, otherwise, a corresponding amount of defoaming agent is added according to the pollution index of the foam floater at the moment to carry out the defoaming treatment step until the pollution index of the foam floater is in the threshold value interval with the minimum pollution index of the foam floater after the defoaming treatment is finished. Foam floaters on car washing wastewater can be defoamed by adopting the defoaming agent. And when the foam floater defoaming treatment step is finished, the car washing wastewater is subjected to foam floater volume acquisition, and if a certain amount of foam floater exists in the car washing wastewater, a corresponding amount of defoaming agent is added again according to the foam floater volume, so that the foam floater on the car washing wastewater meets the treatment standard.
