Embodiment 1

[0012] The malodorous wastewater was taken from the sewage treatment pool of a pharmaceutical factory in Harbin. The malodorous water sample was a yellow turbid liquid with an unpleasant stench. Fresh red bayberry leaves are pulverized, and 0.75g bayberry leaves with green leaf smell are weighed, added in a 30ml Erlenmeyer flask with 15g waste water sample, sealed with a magnetic stirrer, stirred at room temperature for 8h, and the odor completely disappears with sensory evaluation . Then, the waste water and the deodorant red bayberry leaves were separated by filtration, and the waste water was obtained which was odorless and also had the inherent fresh smell of the leaves. The separated deodorant bayberry leaf residue is burned as fuel.

Embodiment 2

[0014] Dry the fresh red bayberry leaves at 40°C for 4 hours, crush them, then use the dried red bayberry leaves as a deodorant, and perform the same operation as in Example 1 to obtain odorless waste water with the inherent smell of leaves.

Embodiment 3

[0016] Using fresh lychee leaves as deodorant, the same operation steps as in Example 1 have been carried out deodorization experiment. Most of the bad smell disappeared, but the bad smell could still be clearly felt, and the deodorizing effect was less than that of bayberry leaves.

Abstract

The invention relates to a waste water deodorization method that uses leaves of fruit trees. The method could achieve ideal deodorization effect, especially suitable for pharmaceutical factory. It is innocuous, and no second pollution, low cost, easy to get raw materials, and easy to operate and has good effect.

Description

Technical field: [0001] The invention belongs to a method for deodorizing malodorous wastewater by using fruit tree leaves as a deodorant. Specifically, it is a method of utilizing red bayberry, litchi leaves and other fruit leaves as a deodorant to deodorize waste water. Background technique: [0002] At present, environmental damage and pollution problems have attracted the attention of people all over the world, and the foul-smelling wastewater produced in industrial production and life is one of the more prominent problems. Smelly waste water pollutes the soil, pollutes the air, pollutes the water, and brings various diseases and poisoning to people, especially in the process of chemical factories, pharmaceutical factories, food factories, printing and dyeing factories, and the drainage process of residents' daily life. Smelly wastewater, in today's environmental protection, energy saving, and increasingly stringent requirements for wastewater discharge standards, peopl...
