Application materials: mining application equipment: plate and frame filter press Scheme Introduction: Mine waste water mainly comes from pit water discharged from mining production, rain waste water from waste stone yard and ore washing and tailings waste water discharged from ore dressing plant, according to the analysis of Bebon laboratory, there is a certain amount of special acidic waste water in the Experimental Mine waste water, including heavy metals such as mercury, cadmium, lead, chromium and other elements with significant toxicity such as non-metallic sulfur and arsenic, and there are some toxic elements such as zinc, copper, nickel, etc., and the tailing leachate will cause the pollution of groundwater and soil. The scheme we give is: flow into the three-layer sedimentation tank through the drainage ditch, the water through the three-layer sedimentation tank can be recycled after long precipitation. Use a mixer in the three-layer sedimentation tank, stir evenly, and use a slurry pump to drive the slurry from the three-layer sedimentation tank into the slurry tank. Use the medicament conditioning tank to add medicine (add the medicament into the mud tank through the medicament tank). After the mud tank is evenly stirred by the mixer, it is provided by the plunger Mud Pump (the plunger mud pump needs to be specially customized, using the spherical valve core) dripping into the filter press for dehydration treatment, the mud cake formed by the treatment is pulled away and buried, and the clean water flows into the clear water tank for recycling, finally achieving the purpose of turning the sewage into clean water.
Applied Materials: printing and dyeing wastewater applicable equipment: diaphragm filter press Scheme Introduction: The Laboratory of our company has conducted laboratory analysis on the waste water of the printing factory, and the difficulty is that the quality of the waste water mixed with high concentration waste liquid fluctuates greatly, the conductivity is high and the biological treatment is difficult, it is difficult to remove the index such as amine and AOX. The processing scale of this printing factory is 1000 T/D, and the diaphragm filter press is recommended. This machine adopts the whole structure of concentrated filter press, with compact structure, it occupies a small space and has a relatively large processing capacity, which is suitable for the rapid dewatering treatment of industrial sludge with a large amount of mud. It is a preferred model for sludge dewatering in printing and dyeing industry. Part of the emission standard is used back for production, and the rest reaches the discharge standard of water pollutants in textile dyeing and finishing industry.
Applied Materials: Machine sand applicable equipment: plate and frame filter press Scheme introduction: This project is in Shandong province. After understanding the demand, the Project Department designers of our company designed a combination of sand washing machine recycling integrated machine, sedimentation tank and plate and frame filter press according to the terrain, first, discharge the crushed machine sand into the sand washing machine and recycle all-in-one machine, then discharge all the waste water produced by the sand washing machine into the sedimentation tank, and use the medicament to make the mud precipitate quickly, after sedimentation, the supernatant can be directly discharged or recycled, and the precipitated thick mud can be pumped into the plate-frame filter press through a high-pressure pump, and the filter cake after the filter press has been very dry, it can reach the situation that the hand can't pinch the water completely, and then load the produced filter cake directly through the belt conveyor and transport it to the recycling place designated by the company.
Applied Materials: river sludge applicable equipment: plate and frame filter press Scheme Introduction: With the development of economy, the total amount of sewage discharge continues to increase, and the water pollution situation of river course is deteriorating day by day, which also brings great pressure to the government, the traditional craft will cause the secondary pollution problem of the environment, and in this project we use the plate-and-frame filter press, after the silt at the bottom of the river is twisted and sucked by a winking dredger, sludge sewage is pumped into the rotary drum grille to remove large pieces of garbage and sundries such as bricks, big stones, dead branches, plastic bags, shoes and socks, and then remove strip-like soft impurities through the mechanical grille, and then remove sand through the sand remover, sludge sewage is accelerated and concentrated to 10% through homogenization tank ~ After 15%, the mud water is scraped out by the bottom mud scraper and sent to the filter press for dehydration. After dehydration, the solid content of the mud reaches 65% (the moisture content is about 35% ). The amount of mud cake produced per unit per hour reaches 8 tons, and the separated water quality reaches the National Emission Standard. It has achieved good social and economic benefits.
Applied Materials: Electroplating wastewater applicable equipment: High pressure diaphragm filter press Scheme Introduction: Electroplating wastewater contains more heavy metals, most of which are hazardous wastes with great pollution. The scheme proposed by beibang environmental protection in this project is to use high-pressure diaphragm filter press, this equipment can quickly process electroplating sludge to the moisture content below 50%, with a small amount of conditioning reagent, the moisture content can reach below 40%, forming a mud cake with low moisture content, no viscosity and small volume, reach the standard of electroplating sludge solidification and resource utilization.
