污水处理厂主要构筑物(污水处理场构筑物实物图)

Solid material, usuallyin sacks, is burnt by an automatic cycle of operation. Liquid waste is storedin a tank, heated and then pumped to the sludge burner where it is burnt in anautomatic cycle. After use the ash box can be emptied overboard.2.Disposal to a shore based facilityT什么是污水一体化处理he availability and cost of disposal to shore based facilitiesand the trading constraints such as time in port, access at tanker terminalsand other restrictions have made option “b” less attractive. Oil and sewagesludge incineration may take place in main or auxiliary power plants orboilers, but not whilst in ports or enclosed water.。

Waste incinerationonboard sea going ships is regulated by IMO MARPOL 73/78 Resolution MEPC.176(58),adopted 10 October 2008 and IMO MARPOL Annex VI, Chapter III Regulation 16 andAppendix IV – Requirements for Control of Emissions from Ships – ShipboardIncineration. All new Incinerators installed onboard a ship on or after 1stJanuary 2000 require compliance with the above regulations and shall have IMOType Approved Certificate.? Refined petroleumproducts containing halogens? Sewage sludge andsludge oil either of which are not generated onboard the shipPo小型污水处理一体化设备lyvinyl chlorides (PVCs) can only be incinerated in IMO typeapproved incinerators. In accordance with the Helsinki Convention, all shipsare prohibited to use their incinerators whilst in the Baltic Sea area. SeeAttached “Clean Seas Guide Baltic States” for an overview of the regulationsgoverning this area.。

? Manufacturer’s manualfor the incinerator shall be available onboard.? The unit shall reach600 degrees Centigrade within 5 minutes after start up.? Owners must decide onthe number of hours per day that the Incinerator should be allowed to work.Generally 8-12 hours per day.? Consideration shouldbe made for ships trading in ECA areas (e.g. Baltic Sea) where incineration isnot allowed. Put up suitable notices.污水处理根据处理程度可分为一级处理、二级处理、三级处理(深度处理)一乡镇卫生院污水处理级处理主要是通过物理作用将水中大颗粒悬浮物去除,主要包括:粗格栅-细格栅-沉砂池-初级沉淀池,粗格栅主要是截留大粒径漂浮物,防止对后续构筑物的阻塞,降低一定的处理负荷,细格栅功能与粗格栅类似只是过滤的级别更细,沉砂池主要是去除水中的沙粒减少沙粒对后续设备的磨损,另外有时候沙粒附着大量的有机物,沉砂池常常采用抱起沉砂池,通过曝气作用将沙粒有机物去除掉。
