  • Treatment technology of petroleum refining wastewater

    Petroleum refining wastewater is a kind of industrial wastewater with serious pollution and difficult treatment in the field of treatment. It is characterized by high ammonia nitrogen, complex pollutant composition, high concentration, mostly biodegradable toxic and harmful organic compounds, and large fluctuations in water quality and quantity.

  • Aquaculture wastewater treatment technology

    With the rapid development of livestock and poultry breeding industry in China, it not only drives the development of rural economy, but also brings serious environmental pollution problems The bottleneck of aquaculture wastewater purification is the removal of a large amount of high concentration NH4 + - N, which will be toxic to plants

  • Characteristicstreatment methods of chemical wastewater

    With the rapid development of economy, the environmental pollution caused by the production process of chemical products is increasing, and the harm to human health is becoming more and more common and serious. In particular, most of the organic substances discharged from the production process of fine chemical products

  • Phosphorus removal process of sewage plant

    Since the on-line monitoring of total phosphorus has been fully launched in domestic sewage plants, various sewage plants have experienced many stories, among which the most common is the chemical phosphorus removal process operation in sewage plants. This wave of operation has brought considerable troubles to the sewage plant in terms of technology, economy and management.

  • Studydehydration treatment of residual activated sludgeRefinery

    The residual activated sludge of refinery was dewatered, the flocculant and its dosage were determined, and the effects of relevant operating parameters on sludge dewatering were investigated.

  • Flocculant operation details determine sewage treatment

    Sludge dewatering polyacrylamide solution is best prepared and used now to prevent it from being placed for too long, so as not to affect the treatment effect.

  • Organic sludge treatment project

    Sludge with organic matter as the main component can be called organic sludge. Its main characteristics are high content of organic matter, easy to decay and stink, fine particles

  • Drilling mud wastewater treatment process

    Drilling wastewater is a kind of special industrial wastewater produced in the process of drilling operation.

  • Decolorization technology of printingdyeing wastewater will become the mainstream

    Printing and dyeing wastewater refers to the wastewater discharged from the pretreatment, dyeing, printing and finishing of cotton, wool, chemical fiber and other textile products. The composition of printing and dyeing wastewater is complex. It mainly takes aromatics and heterocyclic compounds as the matrix, and has chromogenic groups (such as - n ^ n -, - n ^ o) and polar groups (such as - SO3Na, - Oh, - NH2).

  • Agents to be ed for improving sludge dewatering performance

    A large amount of surplus sewage will be produced in the process of sewage biochemical treatment, and the moisture content of these sludge usually exceeds 99%. High sludge moisture content is often accompanied by large sludge volume, which leads to high transportation cost, difficult transportation and occupation of a large number of treatment sites. Therefore, the development of high-efficiency sludge dewatering technology has become one of the important topics for environmental protection workers in China.

  • Trend of sewage treatment: Innovation of sewage treatment mode

    After signing the Millennium Declaration in 2000, the member states of the United Nations formulated the Millennium Development Goals (MDGs), of which target 7 is to ensure environmental sustainability. During the Millennium Development Goals period, the proportion of the global population with access to improved sanitation facilities increased from 54% to 68%, and more than 2.1 billion people around the world have access to improved sanitation facilities.

  • Aquaculture wastewater treatment technology

    With the rapid development of livestock and poultry breeding industry in China, it not only drives the development of rural economy, but also brings serious environmental pollution problems The bottleneck of aquaculture wastewater purification is the removal of a large amount of high concentration NH4 + - N, which will be toxic to plants.
