Embodiment Construction

[0015] The present invention is described in detail below in conjunction with embodiment.

[0016] The core of the present invention is to add the sericin itself (i.e. sericin metal complex) of the metal complexation reaction as a flocculant into the waste water of the silk factory to be treated, so that the sericin in the waste water can be coagulated and precipitated to be removed. Because the metal is heavy, and the metal complexation also changes the electric field around sericin, it can precipitate quickly, with short time and high processing efficiency, and is especially suitable for industrial applications. At the same time, in the follow-up sericin recovery process, since the flocculant is a sericin metal complex, it only needs to remove the metal ions in it, and the removal of the metal ions themselves is relatively easy, so the recovery can be greatly reduced. cost and improve recycling efficiency.

[0017] The concrete steps of this method are:

[0018] 1. Prepara...

Abstract

The invention discloses a treatment method for wastewater containing sericin, which utilizes sericin itself to undergo a coordination reaction with metals to synthesize a sericin metal complex, and uses the complex as a flocculant to agglomerate and precipitate silk factory wastewater sericin, so as to effectively treat the wastewater, and finally recover the sericin protein at low cost by dilute acid washing. The method not only solves the environmental pollution problem caused by the high chemical oxygen demand of the waste water, but also effectively protects the water quality; at the same time, it realizes low-cost and effective recovery of the sericin in the waste water, turning waste into treasure. The development and implementation of this new process will bring not only good social benefits but also considerable economic benefits to silk enterprises in terms of wastewater treatment, so it has broad industrial application prospects.

Description

technical field [0001] The invention relates to a method for treating wastewater, in particular to a method for treating wastewater containing sericin protein. The method can effectively recycle the sericin in the wastewater at low cost while treating the wastewater in silk factories. Background technique [0002] Wastewater from silk enterprises is very different from wastewater from processing industries such as starch, beer, and fruit juice. Its main substances are dissolved sericin and pupal acid. Since the 1930s, scientists in China, Japan, and South Korea have conducted a lot of research on the structure and properties of silk. In the results so far, they have learned that the fiber utilization part of silk is silk fibroin, and the surface The main function of sericin, a highly viscous soluble globular protein, is to make the cocoon silk dissociate smoothly and protect silk fibroin during the silk reeling process, and the final silk product does not contain sericin.
