Description

Technical Field

[0001] The utility model relates to the technical field of pesticide production wastewater treatment, in particular to a pesticide production wastewater treatment device. Background Art

[0002] With the improvement of my country's agricultural modernization level, the level of pesticide use in my country's agricultural production process has also increased, which has promoted the development of my country's pesticide industry. According to data, my country's chemical pesticide technical output in 2018 was 2.083 million tons. According to incomplete statistics, the national pesticide industry discharges about 1.5 billion tons of wastewater each year, but 7% of the total has been treated, and the amount that meets the treatment standards is even smaller, accounting for only a few percent of the treated amount. Pesticide wastewater, as a difficult-to-treat high-concentration toxic organic wastewater, has the outstanding characteristics of complex wastewater composition, unstable water quality and quantity, and high concentration of organic matter. Pesticide production companies generally install pesticide wastewater treatment equipment.

[0003] When treating wastewater generated in the pesticide production process, the pesticide production wastewater treatment device generally uses activated carbon adsorption to adsorb toxic and harmful substances in pesticides. However, the adsorption effect is poor and the treatment time is long. Secondly, during the waterfall treatment, the air pressure in the treatment tank will gradually increase. When exhausting to the outside, it is through the exhaust pipe. When exhaust is not needed, the exhaust pipe needs to be manually closed, which is time-consuming and laborious. Finally, when the sewage is treated with a reverse osmosis membrane device, the treatment time of a single number of reverse osmosis membrane structures is long, and the number of reverse osmosis membrane structures cannot be selected according to needs. Therefore, a pesticide production wastewater treatment device is proposed to address the above problems. Utility Model Content
