It was studied that the process conditions of treating fluobenzene wastewater with acidification, extraction, inorganic fluoride removal and electrocatalysis.
The wastewater of hexanolactam (nylon) fiber production in Shijiazhuang Synthetic Fiber manufactory is high concentrated with organic nitrogen compounds.
If the wastewater concentration was too high, it would stimulate fungus, aminate bacteria, denitrifying bacteria and some anaerobic bacteria to propagate.
An experiment on removing suspended solid(SS)from carclazyte catalyst production wastewater was carried out using 4 inorganic flocculants and 3 organic flocculants.
The source and damage of manganiferous wastewater were introduced. The control technology, sewage purification means and water resources protection were discussed.
The optimized conditions for phosphorus recovery as hydroxyapatite from wastewater by synthetic tobermorite through seeded crystallization were studied in this paper.
Primary modified process of natural clinoptilolite was introduced, with focus on application of both natural and modified clinoptilolite in wastewater treatment.
The experiment of a combined process of"biological contact oxidation and micro-filtration(MF) membrane" was conducted for the advanced treatment of aquicultural product processing wastewater.
As a new technology of organic pollutant degradation, the photocalalytic method, which effectively decomposes nondegradable pollutants, is becoming increasingly important in wastewater treatment.
Results showed that internal electrolysis pre-treatment of yeast-producing wastewater were effective on the removal of COD and colority.What is more important is that the biod...
Since the SS in the wastewater is very high, the anaerobic treatment could be divided into fermentation with decantation or without decantation according to SS treatment.
A process for decolourization of anionic dye containing wastewater by using waste plastics in the presence of cationic auxiliary and sodium dodecylbenzene sulfonate has been studied.
Methods Certain amounts of and Zn were put into the wastewater to produce hydrogen (H2) and the H2 reacted with S2-to form H2S, and sulfuret was separated from the wastewater.
