Silk floss production wastewater treatment process

Abstract

The invention discloses a silk floss production wastewater treatment process. The process comprises the following steps of: silk floss wastewater, an acid precipitation reaction tank, an air stripping tank, a pneumatic sedimentation tank, a sludge tank I, a sludge concentration tank I, a sludge dewatering system I, first outward transportation treatment, a pH regulating tank I, a sedimentation tank I, a sludge tank II, a sludge concentration tank II, a sludge dewatering system II, second outward transportation treatment, an water hyacinth treatment tank I, a hydrolysis acidification tank, a sedimentation tank II, a pH regulating tank II, water hyacinth treatment tank II, a decolorizing tank, a sampling detection tank and discharge. The process has the beneficial effects that: through the arrangement of the water hyacinth treatment pond I and the water hyacinth treatment pond II, treatment steps are effectively reduced, wastewater treatment steps are reduced, resources are saved, and the effect of purifying industrial wastewater or domestic sewage containing a lot of organic matters by water hyacinth is more ideal; the wastewater is treated by physical, chemical and biological methods, so that wastewater purification is facilitated, pollution is reduced, and water resources are fully utilized.

Description

technical field [0001] The invention relates to the field of silk floss production, in particular to a silk floss production wastewater treatment process. Background technique [0002] Wastewater treatment is to use physical, chemical and biological methods to treat wastewater, purify wastewater, reduce pollution, so as to achieve wastewater recycling and reuse, and make full use of water resources. Agent, demulsifier, defoamer, pH adjuster, redox agent, disinfectant. A good plant for monitoring environmental pollution. It can monitor whether there is arsenic in the water, and can also purify harmful substances such as mercury, cadmium, and lead in the water. During the growth process, it can absorb a large amount of nutrients such as nitrogen, phosphorus, and certain heavy metal elements in the water body. , water hyacinth is more ideal for purifying industrial wastewater or domestic sewage water containing more organic matter; when silk cotton production wastewater is tre...

Agent, demulsifier, defoamer, pH adjuster, redox agent, disinfectant. A good plant for monitoring environmental pollution. It can monitor whether there is arsenic in the water, and can also purify harmful substances such as mercury, cadmium, and lead in the water. During the growth process, it can absorb a large amount of nutrients such as nitrogen, phosphorus, and certain heavy metal elements in the water body. , water hyacinth is more ideal for purifying industrial wastewater or domestic sewage water containing more organic matter; when silk cotton production wastewater is treated, the existing wastewater treatment process is relatively complicated, resulting in higher wastewater treatment costs
