In a pharmaceutical and chemical park surrounded by greenery in Yichun City, Jiangxi Province, a silent yet crucial technical operation is taking place in the sewage treatment workshop. A hydraulic explosion-proof diaphragm filter press with model XMYG20/870-30U is responsible for treating special industrial wastewater generated in the pharmaceutical and chemical production process.
The composition of pharmaceutical and chemical wastewater is complex, usually containing residual drug active ingredients, chemical synthesis intermediates, various organic solvents, and high concentrations of salt substances inside. This type of wastewater not only has poor biochemical properties, but some components may also have biological toxicity, making it much more difficult to treat and environmentally friendly than ordinary industrial wastewater. Due to its characteristics, traditional treatment methods often seem inadequate, and the introduction of specialized pressure filtration equipment aims to achieve breakthroughs in sludge reduction.
The slurry pump is used to transport materials for this filter press. Faced with pharmaceutical and chemical sludge containing a large amount of suspended solids, uneven texture, and corrosive potential, slurry pumps demonstrate their strong adaptability. It can effectively enhance and transport this high concentration, high abrasion mixed slurry, ensuring that the material stably enters the filter press for subsequent processing.
When sludge mixed with multiple chemicals is injected under pressure into a series of closed filter chambers inside the filter press, the unique diaphragm pressing system of the equipment begins to work. Under hydraulic drive, the elastic diaphragm performs uniform and stable secondary pressing on the sludge inside the chamber. This process greatly improves the dewatering efficiency and can further squeeze and separate the "bound water" inside the sludge particles that is difficult to remove by gravity.
As the pressure filtration cycle ends and the equipment unfolds, it can be observed that the tightly formed and dry surface filter cake automatically falls off. The moisture content of these filter cakes has been deeply reduced, and obvious fracture surfaces can be seen when broken by hand, achieving effective volume reduction. This not only significantly reduces the disposal volume and cost of hazardous solid waste, but also creates favorable conditions for possible thermal energy recovery or safe incineration disposal in the future. At the same time, the filtered liquid separated by squeezing is collected and reintroduced into the more refined deep water treatment system in the factory area for the next stage of purification, striving to achieve the recycling or standard discharge of water resources.
In Yichun, a city that values the coordinated development of ecological environment and industry, the pharmaceutical and chemical industries, as an important component of its industry, have received much attention for their clean production level. The application of deep dewatering technology for high difficulty and high characteristic sewage reflects the high level of responsibility of enterprises for environmental protection and social responsibility while pursuing economic benefits. It transforms potential pollution risks into controllable governance targets through solid technological means, and builds a reliable technical defense line to protect the local green mountains and rivers.
