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.
Applied Materials: Oilfield mud applicable equipment: plate and frame filter press Introduction of the scheme: After the analysis of the samples by the Bebon laboratory, it is found that the sewage treatment of the oilfield is mainly to remove the oil, suspended solids and other unfavorable components that hinder water injection and easily cause corrosion and scaling of the water injection system, therefore, the researchers decided to lift the waste mud discharged during the drilling process to the debris cache device through the mud collecting box, and use the pump to lift it to the desilking coagulation tank, use dry powder adding machine to add lactating and coagulating drugs quantitatively. The coagulation liquid is pumped from the ceramic double-cylinder pump to the skid-mounted plate-frame filter press for solid-liquid separation. The separated mud cakes are transported out of the filter press unit by the belt conveyor, and the filtrate enters the subsequent purification treatment device. After working procedures one by one, the emission will finally meet the requirements.
Production and operation management refers to the in-depth investigation of the whole process or part of the whole production and operation system of the enterprise through interviews with the enterprise, data collection and going deep into the production site to grasp the current situation of production and operation management, then combine modern scientific methods to put forward improvement measures for various problems existing in the production and operation system, and its fundamental task is to provide the required quantity of qualified products and satisfactory services within the time required by users.
From manual filter press to mechanical filter press, and then to automatic filter press, the whole process is from simple to complex, from low-end to high-end, from artificial to information technology evolution process. So what kind of filter press equipment can become the automatic filter press, then what aspects does the automation level of the automatic filter press specifically reflect in?
The final disposal result of this sludge treatment is that our company provides the corresponding technical route of sludge deep dewatering, including the system design of sludge depth, laboratory detection, manufacture, debugging, installation, after-sales service and other services of one line, equipped with diaphragm filter press, through the high-pressure membrane Dewatering technology, the sludge with water content of 85% in the sewage plant can be treated out, and the water content of the sewage plant can be adjusted and dehydrated to below 60%, the filter cake after deep dehydration can be directly landfilled, burned for power generation, compost, brick making, cement and so on.
