Problems solved by technology

[0002] Silk reeling wastewater mainly comes from cocoon cooking, silk reeling, re-shaking and other sections. Silk reeling wastewater contains a large amount of organic matter such as sericin and silk fibroin. If it is discharged directly without treatment, it will not only seriously pollute the environment, but also cause water pollution. waste of resources

Embodiment 1

[0013] The invention discloses a process for treating silk reeling wastewater, and its specific process steps are as follows:

[0014] (1) The cocoon cooking liquid wastewater is discharged into the centralized treatment pool, and cold water is passed into the centralized treatment pool, so that the temperature of the mixed liquid in the centralized treatment pool is 20-25°C;

[0015] (2) The vertical reeling wastewater can be directly discharged into the centralized treatment pool because it contains less organic matter;

[0016] (3) Taitou wastewater should be pre-filtered to remove the floating grease in the upper layer;

[0017] (4) Neutralize the Taitou wastewater by adding a high-concentration hydrochloric acid solution, so that the pH of the neutralized wastewater is 6-7;

[0018] (5) Discharge the waste water from Taitou into the centralized treatment pool, and pour kaolin sludge into the centralized treatment pool for sedimentation and adsorption.

Abstract

The invention discloses a treatment process of silk reeling wastewater. The treatment process of the silk reeling wastewater particularly comprises the following process steps: discharging cocoon cooking liquid wastewater into a centralized treatment pool and introducing cold water into the centralized treatment pool to enable the temperature of mixed liquid in the centralized treatment pool to be20 to 25 DEG C; directly discharging multi-end reeling wastewater into the centralized treatment pool because the multi-end reeling wastewater contains few organic matters; performing filtering treatment on frigon wastewater in advance and filtering to remove oil floating objects on the upper layer; adding a high-concentration hydrochloric acid solution into the frigon wastewater to perform neutralizing treatment to enable the PH of the neutralized wastewater to be 6 to 7; and discharging the frigon wastewater into the centralized treatment pool, pouring kaolin sludge into the centralized treatment pool and performing precipitation adsorption. The treatment process is simple in step, the cocoon liquid wastewater, the multi-end reeling wastewater and the frigon wastewater are treated separately and singly, and wastewater treatment negotiation among official websites is avoided, so that the treatment quantity of wastewater can be reduced and the input cost of the wastewater is reduced.

Description

technical field [0001] The invention relates to the technical field of environmental protection treatment, in particular to a treatment process for silk reeling wastewater. Background technique [0002] Silk reeling wastewater mainly comes from cocoon cooking, silk reeling, re-shaking and other sections. Silk reeling wastewater contains a large amount of organic matter such as sericin and silk fibroin. If it is discharged directly without treatment, it will not only seriously pollute the environment, but also cause water pollution. Waste of resources. Therefore, the silk reeling wastewater must be treated in depth, so it is necessary to propose a treatment process for the silk reeling wastewater. Contents of the invention [0003] In order to solve the defects of the prior art solutions, the invention discloses a treatment process for silk reeling wastewater. [0004] The invention discloses a process for treating silk reeling wastewater, and its specific process steps a...
