Embodiment Construction

[0025] Below in conjunction with specific embodiment and accompanying drawing, technical scheme of the present invention is described in further detail;

[0026] Such as figure 1 As shown, the laver processing wastewater WS1 enters the wastewater collection tank 1, and the volume of each wastewater collection tank is 500 cubic meters. When the liquid level reaches the production requirement, start the water pump B1, extract the wastewater and send it to the wastewater separator 2, and the wastewater enters the separator 2 in a tangential direction In the separator 2, a vortex-like water flow is formed, and heavier impurities such as sediment settle to the bottom, and the valve F1 is opened every 2 hours to release impurities such as sediment, which are piled up and used for planting vegetables. Overflow to waste water filter press 3;

[0027] After the wastewater enters the filter press 3, most of the water is removed, and the removed water enters the sedimentation separator ...

Abstract

The invention discloses a laver processing wastewater circulation comprehensive utilization system and a technological method, belongs to wastewater treatment technologies in the field of agriculturalproduct processing and also belongs to waste comprehensive treatment and utilization technologies in the field of agricultural product processing. By adopting the technological method provided by theinvention, the problem that wastewater is directly drained to cause environmental pollution in the laver processing process can be solved, laver processing wastewater can be recycled, water resourceconsumption of laver processing is lowered, removed impurities can perform intensive processing with a high added value, and health sustainable development of the laver industry is facilitated.

Description

technical field [0001] The invention relates to a recycling and comprehensive utilization system and technical method of seaweed processing wastewater, which belongs to the wastewater treatment technology in the field of agricultural product processing, and also belongs to the comprehensive treatment and utilization technology of waste in the field of agricultural product processing. Background technique [0002] Porphyra is a collective name for marine algae belonging to the genus Porphyra of the Russetaceae family, including Porphyra spp. [0003] Seaweed is rich in nutrition. According to different growth periods, the protein content of every 100g dried seaweed is 35-50%, the content of polysaccharide is about 25%, and the oil content is about 3%. The oil content in seaweed is mainly polyunsaturated fatty acid. It is particularly worth mentioning that seaweed also contains a special amino acid --- taurine, which is not contained in any land plants. The content of taurine ...
