Rural sewage is roughly divided into two categories of gray water and black water, of which gray water, including bath water, washing water, dishwashing water, etc., black water is the toilet water, rural sewage as long as the pollutant composition, if COD, ammonia nitrogen, phosphorus, nitrogen, total high. However, rural areas generally do not have sewage collection official website, coupled with the relative dispersion of farmers living, so it is not possible to use centralized sewage treatment plants like the city, a better way is to adapt to local conditions, the use of decentralized governance model, in situ purification.
At present, decentralized wastewater treatment technology is also relatively mature like activated sludge, A?/O, MBR, MBBR and other biotechnology, have a good practical effect. Of course, the selection of composite process of sewage treatment equipment better, listed companies in the field of environmental protection, the first river environmental protection below the village and township sewage treatment system specializing in research and development and services, the product is the integrated decentralized sewage treatment system.
Integrated decentralized wastewater treatment system, is a collection of A?/O, MBBR, contact oxidation and other biological treatment processes in one integrated, automated new buried wastewater treatment equipment, can be conveniently installed in a single household, to achieve the countryside decentralized wastewater collection, high efficiency, low-cost treatment and reasonable reuse of resources.
The main features of the words 1, low cost: the equipment does not have to lay complex pipeline network, there is no large-scale infrastructure, the installation cost is quite low; 2, photovoltaic power generation, green energy saving: there is a photovoltaic power generation module, does not consume the electricity bill of farmers, but also to provide farmers with intelligent lighting; 3, easy to install, short construction period: in the same conditions of the treatment capacity, the system design is more intensive and compact, not only easy to transport, and buried installation occupies an area of land. 4, advanced process: the use of multiple biological treatment process, with 14 national invention patents and new utility patents; 5, self-mixing technology, low failure rate: the use of gas lift technology to achieve purification tank water flow purification, without the installation of pumps and other auxiliary equipment, greatly reducing the failure rate; 6, easy to operate, easy to maintain: degradation capacity, less residual, to ensure that the internal sludge minimization, resource treatment, maintenance intervals of up to 1 year, but also do not need to be manned.
