Embodiment 1

[0029] 1. Early preprocessing

[0030] After the production wastewater is filtered by the pipe network, it enters the 9-stage grease trap. Each stage of the grease trap collects oil from the upper part, and the waste water enters the next stage from the lower part through the partition. A large amount of grease is mainly in the first and second grease traps. , needs to be extracted in time, and transported to the black rosin processing workshop to produce black rosin; the remaining floating oil in the grease trap is regularly opened by the ball valve and discharged into the low-level oil pollution collection tank for pumping to the black rosin processing workshop.

[0031] After the oil separation, the wastewater is lifted into the vortex air flotation system. This process requires the addition of 1-2‰ PAC flocculation demulsifier to promote the demulsification and separation of the emulsified oil in the wastewater. After being separated by the vortex air flotation system, the ...

Abstract

The invention discloses a wastewater treatment method in a turpentine production process. The treatment method comprises: leading the pre-treated wastewater into an anaerobic pool, inoculating the wastewater with anaerobes, decomposing organic matters in the wastewater with the anaerobes, converting the obtained wastewater into a contact oxidation pond, inoculating the obtained wastewater with aerobes, and allowing the aerobes for mass propagation to consume a large number of organic pollutants for purifying the wastewater. Microbial strains take organic matters, such as carbohydrate, ammonia, nitrogen, phosphorus, protein and the like, in wastewater as nutrient sources for continuous growth and propagation, so that the organic matters in the wastewater is constantly consumed, and finally organic matters in the wastewater are reduced, and the water quality becomes better.

Description

technical field [0001] The invention belongs to the technical field of rosin wastewater treatment, and in particular relates to a wastewater treatment method in the rosin production process. Background technique [0002] Rosin is one of the varieties with the largest production volume in forestry chemical products. It has excellent properties such as anti-corrosion, moisture-proof, insulation, adhesion, emulsification, and softening. Pesticides and other fields have been widely used. However, rosin itself has some defects, such as easy crystallization, easy oxidation, high acid value, low softening point, etc., which limit the application of rosin. The modification of rosin is the driving force for the development of rosin industry. Through modification, it not only makes up for the defects of rosin itself, but also develops new products and expands the use of rosin. After deep processing of rosin, the application field can be continuously expanded. At the same time, with...
