Shaoxing Makes Use Of Technology To Realize Energy Saving And Emission Reduction In Printing And Dyeing Leather Making

< p > in the face of the situation of "a href=" //www.sjfzxm.com/news/index_c.asp "> printing and dyeing > /a", the situation of large quantity of enterprises, the large amount of sewage discharged from the NNP and the limited enforcement force of environmental protection, how to strictly control and control the sewage of enterprises?

Whether the enterprise has sewage, automatic valve can report, whether the sewage concentration has exceeded the standard, on-line monitoring can see; the temperature water flow out, infrared thermal imager can be found.

< /p >

< p > as a pilot project in the province, Shaoxing county has launched the automatic monitoring system of pollution sources several years ago.

In this system, on-line automatic monitor, flow rate meter and operation recorder of pollution control facilities are installed on the pollution source site to monitor and monitor the discharge of pollutants.

As of 2012, Shaoxing county has built 224 automatic monitoring systems for pollution sources, covering 17 towns and development zones such as Binhai, Qian Qing, Yang Xunqiao, etc., and networking with the environmental monitoring center of the environmental protection departments at higher levels, improving the supervision level of pollution sources in all directions, and ending the supervision of "depending on the waste water, relying on the waste gas and listening to noise", so as to realize the real-time supervision of pollutant discharge of enterprises, and urge enterprises to adjust the industrial structure.

< p > September 2012, < a href= "//www.sjfzxm.com/news/index_p.asp > > Shaoxing County < /a > start the construction of automatic control system of industrial enterprises' credit card discharge total amount.

The County Environmental Protection Bureau will put the amount of sewage approved by the enterprise into an IC card every month, and the enterprise will pay off by card. Once the pollutant discharge in the card is used up, the electromagnetic valve of the system installed at the enterprise side will be automatically closed.

This device is also connected with the monitoring center platform set up in the County Environmental Protection Bureau building.

In February last year, when the credit card sewage system was put into operation in the first phase, it could only control the total amount of industrial wastewater discharge in the county.

By the end of last September, the two phase of construction was completed, and the real time monitoring of pollutant concentration was achieved.

Up to now, the county has installed 214 sets of credit card sewage system, involving 222 enterprises, and achieved five coverage of printing, dyeing, electroplating, paper making, leather making, chemical industry and so on.

< p > "after the operation of this set of equipment, it is like waiting for the" electronic police "to be on duty.

Shaoxing County Environmental Protection Bureau ecological science and technology development division responsible person told reporters that when the amount of sewage discharged by enterprises reached 80%, 90% and 100% approved, the monitoring platform will display the current sewage discharge status in three different colors of blue, yellow and red. At the same time, the system will automatically send SMS messages to the person in charge of the enterprise, the environmental protection administrator and the environmental protection department responsible person.

When the amount of emissions reached the approved amount, the staff of the County Environmental Protection Bureau immediately informed the enterprise, and the computer closed the sewage valve remotely.

At the same time, when the COD concentration of the main pollutants in the sewage exceeds the standard, even if the total amount of sewage has not yet exceeded, the valve will also automatically shut down.

< /p >

The operation of the "P" credit card sewage system has enabled the Shaoxing Environmental Protection Bureau to firmly control the total amount of waste water discharge and the COD emission concentration of the main pollutants. The impartiality and effectiveness of the county environmental protection bureau have also been greatly strengthened.

The total amount of sewage discharged from the county was stable at 540 thousand tons / day from 760 thousand tons per day.

The original environmental protection department shutting valves need to cooperate with the water department to operate on the enterprise site. Now, as long as the computer remote control is adopted, the valve can be closed by clicking with the mouse, avoiding direct contact between law enforcement officers and enterprise bosses, preventing the breeding of "acquaintance economy" space, and effectively reducing human rights enforcement.

< /p >

< p > "credit card pollution" forced pformation and upgrading of enterprises, and careful calculation.

Up to now, the County Environmental Protection Bureau has issued more than 3 credit card warning and SMS messages, and 135 (time) enterprises have been shutting down valves because of excessive emission.

Enterprises are under great pressure, forcing themselves to tap the potential from the inside, eliminate the bath equipment, introduce low energy consumption and high-grade production equipment, and increase the production mode from quantity growth to benefit growth.

< /p >

< p > 2012, infrared thermal imager was introduced in Shaoxing county.

This technology is to use infrared thermal imaging technology to detect infrared radiation of target objects, and pform the temperature distribution image of objects into video images by means of photoelectric conversion and signal processing.

In the night law enforcement inspection, some enterprises secretly buried underground pipes and stole sewage. The environmental law enforcement officers could detect traces of waste water within the radius of 500 meters through this "new weapon".

After the application of the equipment, 5 enterprises were shut down for rectification of illegal sewage.

< p > > a href= "//www.sjfzxm.com/news/index_s.asp" > Technology Supervision < /a > makes the positive energy of environmental protection effectively enhanced, and also enables enterprises to improve efficiency through energy conservation and emission reduction.

According to statistics, at present, 210 enterprises in the county have completed the operation of sewage pretreatment facilities, and the daily processing capacity is 570 thousand tons; 65 enterprises have completed the operation of reclaimed water reuse facilities, and the daily reusing capacity is 200 thousand tons; the 19 printing and dyeing enterprises use membrane treatment technology to reuse wastewater, and the recycling rate is over 60%.

Next, the Shaoxing County Environmental Protection Bureau plans to extend the science and technology regulatory system to more and more micro pollution enterprises in the breadth, and expand the field to the monitoring of stereotype exhaust gas.
