Deep concentration technology of high salt wastewater
In this paper, the technical and economic comparison of DTRO, ED, multi-effect flash and low temperature flue gas concentration is made. Deep concentration reduction refers to the use of technical means to separate part of the water in the high-salt wastewater, leaving the end wastewater with a higher salt content, and the end wastewater can not be further concentrated and can be directly considered for curing treatment.

Biochemical tank operation management manual
In actual operation, temporary control measures should be given priority according to the actual situation to prevent the failure of the system caused by massive sludge loss. At the same time, it should also carefully analyze the causes of sludge swelling, start from the root, take the adjustment means of process operation, and control the occurrence of swelling. For treatment plants where sludge bulking occurs more frequently and the degree is more serious......

Design of arsenic-containing wastewater treatment process
Metallurgical, mining, chemical, dye and leather industries in the production process will produce a large number of arsenic containing wastewater, if not properly treated, will cause serious pollution to soil, water, affect the growth of crops, threaten the health of humans and animals. Gb5749-2006 and GB8978-1996 stipulate that the mass concentration of arsenic in drinking water and discharge wastewater cannot exceed 0.01×10-6 and 0.5×10-6kg/m3, respectively......

Anaerobic ceramic membrane reactor-double membrane process for reuse of wastewater from automobile parts production
The production process of auto parts is complicated, and the waste water produced contains resins, surfactants, paints, pigments, heavy metal ions and other pollutants. At present, the traditional process of coagulation-pretreatment (Fenton or hydrolysis) -biological treatment, followed by advanced treatment (such as adsorption, etc.) has many shortcomings, such as too many treatment units, poor load resistance, difficulty in achieving stable standards, and insufficient reuse of effluent......
