Second, process
3, the basic principles of
The device is the use of micro-processing technology combined into a new type of highly efficient sewage purification plant. It consists of bio-septic tank body, microbial flora, microbial carrier so on. Mainly through the manual to strengthen technology, microbial flora introduced into the bio-septic tank within a one-time, in the pool gradually formed on the bio-carrier biofilm bacteria, the use of microbial flora (biofilms) of the metabolic role of the absorption, 5
digestion, decomposition of sewage organic pollutants, so that transformed into a stable harmless substances, water purification purposes. The process uses a multi-level combination of biological treatment processes. The whole system buried in the ground, water can get into this system without any energy consumption, the use of plug-flow fluid siphon technology to automatically along the inside of the special structure of successive flows through the adjustment, precipitation, separation, multi-stage biological treatment, multi-stage oxidation treatment clarification process. In the system is equipped with a special GSH bio-carrier, to facilitate microbial conjunctiva survive and multiply. In the normal operation of the device installed, the one-time join the group of cultivated GSH microbial strains can be life-long run; the microbial flora contains many kinds of bacteria spectral width, degradation of organic matter ability, treated effluent through the public health, epidemic prevention and environmental protection unit to monitor and fully meet the latest requirements of the state of the GB8978-1996 ‘Integrated
Wastewater Discharge Standard’, can be discharged into the sewers and around the water nearby.
In the sewage treatment process, will produce some of the 6
methane gas and a small amount of nitrogen oxide gases, because of their low concentration and not pure, it can not be recycled and will not cause an explosion, may be flowing through the sewer pipe discharge or high-altitude emissions. Approval from the environmental, public health departments to monitor gas emissions in line with national environmental protection requirements, does not affect the living environment air quality. Treated water, such as the reuse can drain, an additional water flow-back water installations for the water plants, trees, washing vehicles, ground toilets and so on. This is a technology for environmental protection, the micro-organisms in the bio-engineering. The principle is to natural water bodies of various micro-organisms through a special separation and purification equipment to cultivate domesticated, concentrated into a highly active preparation of cured, high-density multi-mix powder agent (or agent) to be stored. At normal temperature and pressure conditions, the powder agents can be stored six years.
We developed a high GSH series of microbial activity, high concentration (10 billion / g powder agents), high-mix (dozens - hundreds of kinds / g powder agents). Applications for different bodies of water pollution, water quality and sewage 7
pollution factors and concentration conditions, choose the degradation have the best advantage of microbial groups (divided into A, B, C, D, E-type series) and the required the number of bacteria with special devices will
"activate" after, and then put into the sewage treatment plant system (or the city’s sewage river, drainage, ditch, lake), can absorb and digest the sewage decomposition of organic pollutants and other harmful ingredients. The installation of septic tanks due to a special bio-bio-carrier, to facilitate micro-organisms attached to the conjunctiva and metabolism, will not be affected by the Ambassador of water impact load over the loss of a large number of micro-organisms.
4, the application scope of
The technology and devices is currently the best way to sewage treatment. Apply to office buildings, residential areas, residential areas, commercial communities, hotels, canteens, schools, resorts, hospitals, military barracks, trains, ships and other domestic sewage purification treatment.
