Rosin resin production and processing wastewater treatment equipment and treatment method thereof

Abstract

The invention relates to the technical field of environmental protection equipment, and discloses rosin resin production and processing wastewater treatment equipment and a treatment method thereof. The rosin resin production and processing wastewater treatment equipment comprises a square shell, wherein a water inlet pipe and a water outlet pipe are arranged at the two ends of the shell respectively, and the shell is obliquely arranged. According to the rosin resin production and processing wastewater treatment equipment and the treatment method thereof, flow guide holes are sequentially formed from top to bottom so as to prolong the wastewater flowing distance; in the flowing process, the layering direction and the flowing direction are kept consistent, upper-layer waste oil is recovered through a precipitation cavity and a waste oil recovery cavity, and lower-layer precipitate is recovered through the layering cavity and the precipitate collection cavity so as to achieve layering and precipitation during the flowing process; and the oil and the wastewater have different heights on the capillary tubes made of different materials, such that the waste oil can be sucked out when the upper layer is the waste oil, and the wastewater cannot be sucked when the waste oil is the waste water so as to achieve the automatic suction of the waste oil.

Description

technical field [0001] The invention relates to the technical field of environmental protection equipment, in particular to equipment for treating waste water from rosin resin production and processing and a treatment method thereof. Background technique [0002] Rosin resin is a general term for a class of rosin or modified rosin derivatives obtained by esterifying carboxyl groups with alcohols at a certain temperature using rosin or modified rosin as raw materials. A large amount of waste water and waste oil are produced. The pollution of waste water produced in the production process of rosin resin is usually organic pollution, and the concentration of COD is high. Therefore, the treatment of waste water is usually divided into two parts: pre-treatment and post-treatment. Pre-treatment usually uses physical methods. The focus is on recycling the waste oil in the wastewater; the post-treatment mainly adopts a combination of physical and biochemical methods to reduce the CO...

Problems solved by technology

[0003] The pretreatment usually includes an oil absorption system composed of a recovery tank and a grease trap, which uses the phenomenon of natural stratification of liquids with different specific gravity to absorb the stratified oil layer into the recovery tank. Therefore, it takes a long time during the treatment process. Standing for a while, waiting for its natural stratification, so the efficiency is low, and when the wastewater flows in, it will disturb the liquid and affect the stratification effect

[0004] The treatment effect is further reduced. Secondly, when the oil layer is sucked out, it is necessary to pay attention to the thickness of the oil layer at all times. There is a connection process between the oil layer in the wastewater layer and the manual suction. In actual work, the length of the connection time cannot be accurately controlled. It further affects the work efficiency again, and the low efficiency will inevitably lead to an increase in the occupied area. However, the domestic rosin resin industry is mostly based on small-scale processing, and the excessively large occupied area will inevitably discourage its enthusiasm for establishing a sewage treatment system and restrict sewage treatment. development of
