Reasonable technological conditions for the process are obtained through a large number of tests and experiments. Difficult problems present in beer brewing such as dark colority, high acidity and rough taste, are solved and a new type of 11°BX whole mat beer with light and clear features has been developed.
The paper-making Black liquor is an industry wastewater of the most difficult treatment. It has the features of high COD values, deep colour, high contnent of lignin, strong alkalinity and the large capacity of drainage.
Printing and dyeing wastewater is a kind of wastewater with high content of organic matters, high colority and poor biochemical performance and it is hard to be degraded.
Through investigating technics of Doxycycline factories and analyzing the water quality of Doxycycline industry wastewater, the thesis finds that Doxycycline industry wastewater belongs to high density organic wastewater, that it has low acidity、deep color and smell, that its component is complex, that it contains much weak biodegradability and toxicity, and that its biodegradability is not good.
Printing and dyeing wastewater as one of industrial wastewater is hard to treat due to high content of sulphide, deep chromes, high pH value and complicated component.
In a multi layering application, deep colour and depth can be obtained by using in the same manner as a conventional Enamel.

Ferric reduced-neutralized sedimentation was used as the pre-treatment technology for treating mixed chemcial wastewater with high acidity, deep color, toxic and biorefractory in an economic development zone. The test results showed that through pretreatment, the biodegradability of wastewater was improved distinctly, at the same time, color and COD were removed 90 % and 50% respectively. It is an economical and effective pre-treatment technology for this kind of mixed chemical wastewater.
The paper-making Black liquor is an industry wastewater of the most difficult treatment. It has the features of high COD values, deep colour, high contnent of lignin, strong alkalinity and the large capacity of drainage. This paper introduces above characteristics and the results of experimental study of this wastewater treatment with anaerobic process. Under the conditions that T=35±℃,HRT=48h, Nv=10.2kgCOD/m3·d, a COD removal rate of above 80% can be achieved in the anaerobic bacteria treatment. These res...
A new process for whole malt beer production is introduced. Reasonable technological conditions for the process are obtained through a large number of tests and experiments. Difficult problems present in beer brewing such as dark colority, high acidity and rough taste, are solved and a new type of 11°BX whole mat beer with light and clear features has been developed.
