The invention relates to a ship sewage treatment device, and belongs to the field of ships. The sewage entering the air floatation is firstly subjected to large particle filtration through a filtering part in the reaction area, then a flocculating agent and a coagulant aid are added, after effective flocculation reaction, raw water enters the air floatation contact area, microbubbles in dissolved air water are attached to flocculated suspended solids and enter the separation area together, floc and the bubbles rise to the liquid level together to form scum, and the scum is separated from the air floatation contact area. Scum is scraped to sludge by a foam scraping device, clear water on the lower layer automatically flows to a clear water tank through a water collecting pipe, one part of the clear water flows back to be used by an air dissolving system, the other part of the clear water is discharged, and the returned clear water is lifted by a pump and mixed with compressed air in an air dissolving tank to generate air dissolving water containing saturated air; and a liquid level controller is arranged on the dissolved air tank, so that unattended full-automatic operation is realized, the whole equipment is stable in operation and low in failure rate, and the chain slag scraper can realize full-tank coverage and multi-plate slag scraping and is stable and reliable.
本申请涉及一种船舶污水处理装置,属于船舶领域。进入气浮的污水在反应区先通过过滤部件进行大颗粒过滤,再加入絮凝剂和助凝剂,经过有效絮凝反应后,原水进入气浮接触区,溶气水中的微气泡,附着到絮凝好的悬浮物上,一起进入分离区,絮体和气泡一起上升至液面,形成浮渣,实现了固液分离,浮渣由刮沫装置刮至污泥,下层的清水通过集水管自流至清水池,其中一部分清水回流,供溶气系统使用,另一部分排放,回流的清水经过泵的提升,在溶气罐中和压缩空气进行混合,产生包含饱和空气的溶气水,溶气罐上装有液位控制器,实现无人值守全自动运行,设备整体运行稳定,故障率低,链条刮渣机可实现全池覆盖,多板刮渣,平稳可靠。
