CENTRAL WASTEWATER TREATMENT
The objective of waste water treatment is to reduce the concentrations of specific pollutants to the level at which the discharge of the effluent will not adversely affect the environment or pose a health threat. Moreover, reduction of these constituents need only be to some required level. Although water can technically be completely purified by distillation and deionization, this is unnecessary and may actually be detrimental to the receiving water. Fish and other organisms cannot survive in deionized or distilled water.

For any given wastewater in a specific location, the degree and type of treatment are variables that require engineering decisions. Often the degree of treatment depends on the assimilative capacity of the receiving water. DO sag curves can indicate how much BOD must be removed from wastewater so that the DO of the receiving water is not depressed too far. The amount of BOD that must be removed is an effluent standard (discussed more fully in Chapter 11) and dictates in large part the type of wastewater treatment required.

Circulating Water Bactericide

water-circulating

Microorganisms in circulating water of power plant bring great harm to cooling water system. It not only affects the effect of heat transfer, but also would lead to corrosion of heat exchanger, in seriously would result in shutdown. Now the plant uses the bactericide to treat with the microbial fouling generally, and a variety of fungicides have been developed. However, the long-term usage of fungicide will make the bacteria appear resistance, which greatly limits the application of such measures. This paper overviewed different resistance mechanisms of Pseudomonas, sulfate-reducing bacteria, iron bacteria and slime forming bacteria in the microbial fouling to bactericide and put forward some solutions.

Benzalkonium Chloride is one of the Quaternary ammonium class of Cationic surfactants, belonging to nonoxidizing biocide. It is widely used as a disinfectant in the Hospital, Livestock and Personal Hygiene sectors

Isothiazolinones is a kind of fungicidal with properties of broad spectrum, high efficiency, low toxicity and non-oxidative, it is the ideal biocidal in industrial circulating cool water system and in wastewater treatment in oilfield, papermaking, pesticide, cutting oil, leather, detergent and cosmetics etc..

SDIC is water soluble, it has properties of high effective, instant effective, wide range and safety. SDIC has strong fungicide effect, even at dosage of 20ppm, the fungicide ratio can reach to 99%.

TH-409 is composed of cationic surfactant, penetrating agent and dispersant. TH-409 has the advantages of high efficiency, wide range, sterilization, fungicidal, sludge stripping and cleaning
