Abstract

The invention discloses lead-removing equipment for lead storage battery wastewater, which is characterized in that it comprises: a primary reaction zone, a secondary reaction zone, a sedimentation zone, a filtering zone and a water outlet zone, and the upper end of the side wall of the primary reaction zone is provided with The water inlet, the primary reaction zone is connected with the secondary reaction zone through the water outlet of the primary reaction zone at the lower end, and the secondary reaction zone is connected with the precipitation zone through the secondary reaction zone water outlet at the upper end, and the precipitation zone is connected with the precipitation zone The filter areas are connected, and the water is distributed by overflowing water. The filter areas are connected to both sides of the water area through the filter area outlet pipes at the bottom of both sides; the primary reaction area is also connected to the lead removal agent dosing device, The secondary reaction area is connected with a coagulation aid dosing device. The invention has the advantages of simple operation, high treatment efficiency, small floor space, and integration of high-efficiency lead removal technology, sedimentation technology and filtration technology, and solves the problem that the lead-containing wastewater in the current lead-acid battery industry cannot be stably met after treatment and produces a large amount of hazardous waste.

Description

technical field [0001] The invention relates to lead-removing equipment for lead-acid battery waste water, mainly for lead-acid battery industry waste water, in particular to a lead-removal device for lead-acid battery waste water. Background technique [0002] Lead battery wastewater is divided into production wastewater and domestic sewage. Production wastewater mainly comes from lead-containing and acid-containing wastewater generated during the production process of products, from processes such as acid mixing, coating, chemical formation, or ventilation and dust removal water. Contains lead powder, molten lead, lead sulfate, sulfuric acid and some other organic additives and engine oil; lead-containing and acid-containing waste water produced by auxiliary departments such as battery laboratories and battery analysis rooms for battery product testing and analysis rooms; employee work clothes cleaning water , employee shower wastewater, as well as various production proce...
