The collaborative disposal of fly ash using cement kilns involves pre-treatment of the fly ash, extracting resources such as potassium, sodium, and chlorine to produce industrial salt. The remaining desalinated fly ash is then sent to the cement kiln for high-temperature calcination, where dioxins are completely decomposed under high temperature conditions.

Solid waste recycling is the separation and purification of mixed liquid containing multiple solutes by a specific process treatment system, aiming at reducing the burden of solid waste treatment and saving operating costs. The resource utilization process should be combined and individually designed according to water quality parameters and engineering conditions to ensure advanced and reliable technology and reasonable investment and operation cost.

In order to reduce the discharge of industrial wastewater and improve the water environment, chemical, pesticide, electroplating and other enterprises will be included in the scope of industrial wastewater reuse. The reuse of industrial wastewater can not only provide enterprises with a very economical new water source, reduce the project investment generated by long-distance water diversion, but also further reduce the environmental protection cost of controlling water pollution.

Photovoltaic new energy industry production process is complex, each production process and treatment process wastewater collection, the use of pretreatment to remove solid impurities in the water, the use of membrane treatment to filter the organic matter in the wastewater, the use of MVR evaporation crystallization process route, the discharge of distilled water and miscellaneous salt crystallization, so as to achieve the recycling of wastewater.

In recent years, China's lithium battery material market has developed rapidly, of which the production and sales of positive electrode materials have accounted for more than 40% of the world. The cathode material of lithium battery is the key and bottleneck material of lithium ion battery. Qiaofa Technology self-developed concentrated crystalline lithium battery extract. The crude lithium carbonate enters the lithium salt system to produce battery grade lithium carbonate, and the liquid after settling lithium enters the sodium salt system to produce anhydrous sodium sulfate.

There are more than 20,000 domestic pharmaceutical enterprises, and pharmaceutical equipment is the key to the production of pharmaceutical enterprises, and equipment investment accounts for more than half of the total investment. Whether from the perspective of market size or volume, good technology and good products will usher in broad space and opportunities for development.

Hydrometallurgical wastewater usually contains high concentrations of salts, heavy metal ions and organics, which pose a serious threat to the environment and ecological health. Therefore, the evaporation treatment of hydrometallurgical wastewater, the reduction of wastewater and the utilization of resources, has become an urgent problem to be solved.

With the advancement of industrialization, the coking industry, as an important part of energy, chemical industry and other fields, the wastewater treatment problem caused by its development has attracted wide attention. In order to solve the problem of environmental pollution caused by coking wastewater, the advanced evaporation technology has created a new situation for the environmental protection management of coking industry.
