Embodiment Construction
[0016] The present invention will be described in detail below in conjunction with the accompanying drawings and with the best embodiment.
[0017] refer to figure 2 , image 3 , hot-dip galvanizing workshop wastewater "zero discharge" treatment system, including:
[0018] The "zero discharge" treatment system for hot-dip galvanizing workshop wastewater is characterized in that it includes:
[0019] Sewage collection device, using the sewage sump to collect the waste water in the rinsing tank;
[0020] For rinsing water treatment equipment, the water in the sewage collection tank, the water in the alkaline pool, and the clean water are input into the neutralization tank for neutralization, removing iron salts, and adjusting the pH value; the neutralized water is input into the oxidation tank, and sent to the Oxygen is flushed in the oxidation tank; the water in the oxidation tank is input into the inclined sedimentation tank for sedimentation; the waste residue at the bott...

The invention provides a waste water zero emission treatment system for a hot-dip galvanizing workshop, relates to an industrial waste water treatment system, in particular to a waste water treatment system for the hot-dip galvanizing workshop. The waste water zero emission treatment system for the hot-dip galvanizing workshop is characterized by comprising a sewage collecting unit collecting waste water in a rinsing slot via a sewage collecting tank, and rinsing water treatment equipment for inputting water in the sewage collecting tank, water in an alkali tank and pure water to a neutralization tank for neutralization, removing ferric salt and then adjusting a pH value; inputting the neutralized water to an oxidizing can and filling oxygen in the oxidizing can; inputting the water in the oxidizing can to a sloping sedimentation basin for sedimentation; inputting waste residues at the bottom of the sloping sedimentation basin to a plate filter press for pressure filtration; and finally inputting liquid at the upper part of the sloping sedimentation basin to a filtering and sedimentation basin for filtration and sedimentation, and then inputting the filtered and settled water into a pure water tank. The waste water zero emission treatment system solves the waste water treatment problem of the existing hot-dip galvanizing plant, saves finite water resource and protects environment.
Description
technical field [0001] The invention relates to an industrial waste water treatment system, in particular to a hot dip galvanizing workshop waste water treatment system. Background technique [0002] At present, the wastewater in the hot-dip galvanizing workshop is generally discharged or partially discharged, causing serious pollution and waste of water resources. In recent years, a company has invented a "zero" wastewater treatment process, but the existing process only refers to rinsing water, so the treatment of wastewater is not thorough, and it will still cause environmental pollution and waste water resources. Contents of the invention [0003] The purpose of the present invention is to provide a "zero discharge" treatment system for hot-dip galvanizing workshop wastewater. The present invention aims to solve the problem of wastewater treatment in existing hot-dip galvanizing workshops, save limited water resources and protect the environment. [0004] The "zero di...
