Problems solved by technology

[0005] At present, the commonly used algae water separation methods include air flotation method and flocculation sedimentation method. These methods need to add chemical flocculants to the water body. Therefore, there is a secondary pollution problem to the tail water, which increases the difficulty and difficulty of tail water treatment. processing cost

Abstract

The invention discloses a shipborne alga-water separation and tail water treatment device which comprises a dirt sucking pump, a rotational flow separator, a sand collection tank, a hydraulic vibration screen, an extrusion spiral lifting machine, an alga mud collection tank, a settling tank and a clean water tank which are all arranged on the deck of an operation ship. Alga-water separation and tail water treatment are implemented by using a physical method; by using a graded separation method, and based on the rotational flow separator, the hydraulic driving eccentric vibration device with adjustable frequencies and amplitudes, and the settling tank, large-granularity slit, algae and fine-granularity slit can be respectively separated; and the hydraulic vibration screen with adjustable frequencies and amplitudes has good working adaptability to alga-slit mixtures of different concentrations and contents. The device is environment-friendly in alga-water separation and tail water treatment process, meets requirements of ecological alga-water separation, has the advantages of being high in operation efficiency, environment-friendly and energy-saving and safe and reliable, prevents secondary pollution caused by chemical flocculant s on water quality and has great significances for ensuring canal water quality and water conveying security.

Description

technical field [0001] The invention belongs to the technical field of water treatment, and in particular relates to a ship-mounted algal water separation and tail water treatment device and a working method thereof, which are suitable for water areas such as channels, rivers, inland lakes and landscape water bodies. Background technique [0002] With the acceleration of social industrialization, human beings discharge a large amount of pollutants containing nitrogen and phosphorus into water bodies in production and daily life, which accelerates the eutrophication process of slow-flowing water bodies such as lakes and reservoirs, thus causing algae to grow. The frequent outbreak of "water bloom" phenomenon has seriously damaged the ecological balance of the water body and endangered the safety of human beings and other living things. On the one hand, the growth of algae reduces the transparency of the water body, making it difficult for sunlight to penetrate the water layer...
