1. The preferred non-toxic manufacturing process or reform instead of backward production technology, as much as possible to eliminate or reduce the generation of hazardous waste in the production process. 2. In the use of toxic materials and toxic intermediates and products Hospital of the sewage treatment process, should be strictly operating, monitoring, eliminating leakage, reducing wastage, as far as possible and reasonable processes and equipment. 3. wastewater containing toxic substances, such as those containing some heavy metals, radioactive substances, the high concentration of phenol, cyanide and other waste streams should be split, for processing and recovery of useful substances. 4. Flow larger and less contaminated wastewater recycling should be treated properly, should not be discharged into the sewer secondary sewage treatment, so as not to increase the city sewer and urban sewage processing load. 5. similar urban sewage organic waste, such as food processing waste water, sugar water, papermaking wastewater sewage treatment equipment, can be discharged into the municipal sewage system for processing. 6. Some biodegradable toxic waste, such as phenol, cyanide waste, should be treated, according to the allowable emission standards into city sewers, further biological treatment. 7. contain hard-biodegradable toxic waste should be treated separately and should not be discharged into the city sewer. Sewage treatment equipment 1, set processing BOD5, COD, NH3-N, fecal coliform, PH 2 in one, the entire device can be buried in the ground, not an area of ??the surface area; 3, the voice sound generated is low, less smell, little impact on the surrounding environment of the four high degree of purification, the entire system produces less sludge; 5, high degree of automation, easy to manage, no special management; 6, technical stability, easy maintenance 7, low energy consumption and operating cost savings hospital sewage treatment, environmental Runtong (certified), Taiyuan, Shanxi sewage treatment provided by Run-Environmental Engineering Limited.
