This project has been suspended.

Industrial wastewater , such as high-concentration chemical sewage, coking waste water, municipal sewage , livelihood waste water  and others can be pre-treated by other methods,and when  the COD is about of 200mg/l-300mg/l,it can be treated by our microwave equipment as an advanced method,making the COD value to about 50mg/l. At that time,the microwave treating is in high performance and low cost. 
With the aid of non-thermal effects of microwave and select absorbing “sensitizer”, microwave energy can be passed into water and induces pollutants to react, through series of physical and chemical reactions, pollutants are degraded and converted. And this process further promotes the separation between solid and liquid in water. The water after processing has no secondary pollution and can be reused.

Effect showing:
1.Coking wastewater treatment

Project tested	Raw water	Microwave water	Treatment efficiency （%）	National standard （GB16171-2012）
pH	7.52	7.96		6-9
COD(mg/L)	193	35	82	100
BOD5(mg/L)	30	3	90	25
Ammonia (mg/L)	4.2	2.8	33	15

2.Pig farm sewage treatment
Pig farm sewage treatment by microwave chemical method.the water samples of various stages as below:

raw water/ Pretreatment / Intermediate System water / Microwave system water

Project tested	Raw water	Microwave water	Treatment efficiency （%）	National standard （GB18596-2001）
PH	7.75	7.79		6-9
COD(mg/L)	3950	80	98	400
BOD5(mg/L)	800	50	88	150
Ammonia (mg/L)	345	30	91	80
Suspended solids (mg/L)	1200	110	91	200
Quantity of colon bacillus in dung （pcs/L）	3000	500	83	1000

Note: In this case,the COD is high to 3950mg/L which is much than 200-300mg/L. Because the workshop of the customer is very limited,there is no space to install the pre-treating equipment,then much more sensitizer has to be used,which increases the cost of treating.

3.Hospital wastewater treatment

System composition:
The equipment is composed of a microwave generator and microwave cavity.

Feature:
1.Microwave energy wastewater treatment technology could make the treatment project of wastewater miniaturization (small footprint, equivalent to 1/10—1/30 of traditional ones), meanwhile, it has other features such as short process, decentralization and short construction period and saves engineering of burying long distance network of blow-off pipe lines in existing wastewater treatment project and blocks the sources of pollution, which fundamentally eliminate pollution in rivers or lakes caused by human life and production activities.

2.It has features of low investment intensity and overall energy consumption and operating costs for unit of sewage treatment.Set an example of urban wastewater, the processing cost is about 0.8 RMB per ton compared to 1.4—1.6 RMB in common way.

3.It can purify a variety of municipal sewage and industrial waste water and it not affected by ambient temperature and concentration of waste water or pollutants.

4.It has good water processing result and its course can be free to control according to requirement. In addition, because microwave has special action of killing blue-green algae, it can completely remove contaminants and kill pathogens in sewage.

5.In order to achieve the sustainable use of water resources and sewage this equipment can convert the polluted water in rivers or lakes into safe green ones which can be used in industry and agriculture.

6.Microwave can handle benzene and phenol in high concentrations sewage to meet emission standards.

7.It can do deep treatment for high concentration sewage with poor biochemical.

8.It has fast sedimentation of flocculation and improves breaking effectiveness.

9.Miniaturized microwave sewage treatment system.

10.In order to reduce pollution, improve the environment, achieve recycling economy and water reuse and meet better practical requirements, this device can be combined with a variety of traditional methods such as chemical methods and membrane technology.
