tongliao daily: tongliao company applies high technology to treat pollution and realize low consumption
tongliao meihua biotechnology co.,ltd is a national model enterprise, state-level high-tech enterprise for circulation economy development, national agricultural industrialization leading enterprises. since its establishment, it has been creating innovative, resource-saving, environment-friendly, quality and safety-oriented enterprises for their own goals, adhere to the concept of environmental resources, the environment is competitive, and achieved good economic, social and environmental benefits. on may 3, in the organization of municipal party committee propaganda department, directly under the group of four joint interview about tongliao meihua company, enterprise road to high-tech pollution, low energy consumption and emissions.
on may 3, tongliao meihua bio-tech company over the sky was clear, the willow shoots out at the turn of spring and summer give thick greenery. lush green grass, straight road, rows of plants, long vehicles, form a natural, harmonious and development of picture.
investment of 8 billion yuan, annual pre-tax profit of 1 billion yuan, the country's largest sodium glutamate and amino acid products and producers such as brilliant, and tongliao meihua bio-tech company ning shutong made no mention of the party secretary. see reporter, ning shutong said: "meihua group is big business, environmental responsibility is obligatory. fix, environment is to restrict the development of enterprise short board, doing well is the great competitiveness of enterprises. ”
break through world challenge, protect grassland and blue sky
amino acid liquid fertilizer on flue gas treatment in the process of world corn-fermentation industry is technology. during the fermentation of corn drying, heating programs and heating most of the organic compounds are amino acids, proteins, nitrogen, residual sugar, the properties of these substances are volatile, upon heating produces aerosols with a burnt taste, commonly known as "smoke". aerosol once floated into the air is not easy to fall, is not easy to spread out, gone with the wind to a few kilometers outside of. same with domestic, domestic corn fermentation company, smoke problems that had plagued tongliao meihua company.
tongliao meihua company song kun, director of environmental protection, told reporters that industries gas problems are technical problems made by fermenting corn, has little effect on human health, requirements of the national standards of emissions of the company and tongliao meihua company flue gas emissions is in line with national standards.
although in line with national standards, and tongliao meihua charge against smoke always blew. from the company was first established in 2007, drawing on experience and technology at home and abroad, the company processed flue gas to make, has invested a lot, but technical problems cannot be solved overnight problems can be solved. in 2007, tongliao meihua company within the institutions and municipal environmental protection bureau took on the glutamic acid fermentation industry granulation of flue gas treatment technology of the national development and reform commission, research project, 50 million yuan billions invested gave a powerful impetus to the scientific research. after theory and countless experiments, researchers have found, through three stages of scrubbing, release electrons make organisms live and electrodes adsorbed organic three procedures, gas rate of 96% per cent.

follow biological principles, change sewage into clean water
"the domestic media is close is close to the exposed interests of some enterprises in order to secretly discharges, tongliao meihua company this situation?" face reporter sharp of questions, tongliao meihua biological technology limited secretary of the ning shutong laugh with answered road: "if we secretly emissions wastewater, first regardless of outside opinion pressure and related regulatory sector of punished, enterprise itself not only not so get interests, instead whole production cost will significantly upgrade, value super billion of security, and stable production program will by serious threat, face this situation into who i wants to who are not do this hundred victims no a lee of things. ”
tongliao meihua company environmental protection technician hongyu told reporters, tongliao meihua corn processing enterprises in the park, which depends on the enterprise needs through biological method to deal with waste water, the so-called biological method is through the bio-bacteria for wastewater treatment. in 2009, the company invested 190 million yuan to upgrade the sewage treatment plant to expand, introducing netherlands parc the most advanced wastewater treatment technology and biological nitrogen removal process equipment. in two a consumption pool in put from netherlands air and to 10,000 yuan/tons of "soil", this "soil" respectively is anaerobic bacteria and consumption oxygen bacteria, after anaerobic bacteria of no oxygen breathing, wastewater of chemical needed oxygen volume (cod) can from 3000--5000 down to 500--700, again after consumption oxygen bacteria of breathing consumption, wastewater cod will reached 100--200, reached has national sewage emissions 1 level b standard, can directly emissions to river among. under normal circumstances, sewage discharges and the bacteria match the natural productivity, mortality, and once the wastewater the bacteria lose these expensive "food", slowly dying, and overall production process will be interrupted, the consequences would be unthinkable.
in order to fully understand wastewater treatment tongliao meihua company, journalists all watched the entire wastewater treatment equipment. reservoir, black wastewater float to the surface foam, exudes a pungent smell. sewage discharge, wastewater has become yellowish, no smell. in the middle of wastewater discharge monitoring, automatic continuous monitoring system are produced in real time the discharge of sewage discharge, ph value and cod. on the south wall in the monitoring room, the municipal environmental protection bureau online automatic monitoring of pollution sources (monitoring) data acquisition and transmission meter is displaying real-time data. song kun said: "the two monitoring systems are automatically generated data, and networking, the municipal environmental protection bureau can call any time any data at any time. ”
song kun introduced tongliao meihua group currently produces about 20,000 tons of waste water per day, 15,000 tons of treated waste water will enter the muli sewage treatment plants to secondary treatment, treated water cod below 50, the national sewage discharge 1-level standards, can be directly discharged into the ground to become groundwater. remaining 5,000 tons of water entered the company's water recycling workshop, the workshop adopts "double membrane" in water reuse technology, the concentration of reclaimed water reuse in the production system, which saves the groundwater resources, and reduce discharges.
chang the concept of development, turn the waste into valuable product
except for emission reduction, and tongliao meihua also turned to a circular economy way.
at present, tongliao meihua company-owned power station a high pressure steam generation, after generation secondary steam is used in the production, a sector for fermentation of steam-driven air compressor air. electricity, steam, wind three implementation co-production, equivalent to saving 60,000 tons. methane gas produced in the process of ammonia gas for burners to use, after the boiler power generation, but also for the production of steam. sewage treatment plant produces methane gas collected for production use, production of sulfate sulfur when baked in sulphuric acid plant produces a lot of heat and waste heat recovery boilers, and hot steam to the turbines, generating steam for the production of the workshop after decompression.
around the industrial waste water, waste, and tongliao meihua company has made waste, production of fertilizers and feed articles. produced during the production process of high concentration organic wastewater, which contains large amounts of fermentation in the waste water-organic matter and inorganic salts, amino acids, and tongliao meihua company first fermentation in the waste water extracted to produce feed yeast protein, then waste evaporation, granulation, and for production of compound fertilizer to treasure.
tongliao meihua company this year, the environment has reached 700 million yuan, world-class wastewater treatment technology and flue gas treatment technology advanced world, tons of water consumption is the average level of 1/5, the power consumption is the industry average of 3/4 ... ...
"the current business environment has total fixed assets one-fourth, such a large investment into environmental protection enterprises in general, have failed. "tongliao meihua bio-tech company ning shutong, secretary of said, because businesses rely on modern technology, taking the road of scientific and technological enterprises, science and technology of pollution control, tongliao meihua company has created a remarkable green gdp.
