Rural integrated sewage treatment equipment and buried wastewater treatment equipment are just different divisions and classifications of more applied sewage treatment equipment processes. The small sewage treatment equipment adopts membrane bioreactor technology, which is a new equipment combining biological treatment technology and membrane separation technology, which replaces the secondary sedimentation tank in the traditional process, and can effectively separate solid-liquid and obtain stable reclaimed water for direct use. It can also maintain a high concentration of microbial mass in the biological pool, less residual sludge in the process, extremely effective removal of ammonia nitrogen, suspended solids and turbidity in the effluent are close to zero, bacteria and viruses in the effluent are greatly removed, low energy consumption, and small footprint.
Jiangxi Kefeng Water Engineering *** This factory mainly produces MBR membrane integrated sewage equipment and domestic sewage treatment equipment, the equipment does not produce sludge, does not add chemicals, contains membrane backwashing function, does not block the membrane, and can be done in one tank. It can be commissioned to process, OEM production, installation training, free installation and commissioning. The contract promises that the effluent reaches the national first-class A discharge standard, and welcomes to visit the factory.
Technical features: 1. Set up a practical grid system to effectively control the scum or sediment in the sewage.
2. The process is mature, the performance is reliable, and it can meet the first-class discharge standard of effluent;
3. According to the specific water quality conditions and requirements, modularize the design and adjust the relevant parameters, which is more targeted;
4. According to different process requirements, choose different types of biological filter units;
5. Set up biofilm backwashing and automatic transfer system for residual sludge;
6. Automatically adjust the energy-saving aeration mode according to the change of water load, green and low-carbon;
7. Set up a flow adjustment groove or adjustment part to enhance the load impact resistance of the equipment;
8. Set up automatic return systems such as air stripping circulation, metering and transfer;
9. Adopt the bottom mode of the inlet and outlet to ensure the smooth flow and exit of sewage;
The new biological sewage treatment technology adopted by the buried wastewater treatment equipment process of rural integrated sewage treatment equipment integrates the removal of BOD5, COD and NH3-N, and has the advantages of stable and reliable technical performance, good treatment effect, low investment, less land occupation and convenient maintenance. The equipment is buried below the surface, and the surface above the equipment can be used as greening or other land, without the need to build a house, heating and insulation. The two biological contact oxidation treatment processes all use push-flow biological contact oxidation, and the treatment effect is better than that of the fully mixed or two-series fully mixed biological contact oxidation pool.
In addition, the activated sludge tank is small in size, has strong adaptability to water quality, good impact load resistance, stable effluent water quality, and will not produce sludge expansion. The sewage treatment process in the pool adopts the filler of the new elastic three-dimensional reverse osmosis sewage treatment equipment, which has a large surface area, microorganisms are easy to hang the film, and the film is decoated, and the removal rate of organic matter is high under the same organic matter load condition, which can improve the solubility of oxygen in the air in water.
The biochemical tank adopts the biological contact oxidation method, the volume load of the filler is relatively low, the microorganisms are in the stage of self-oxidation, and the sludge production is small, and it only takes more than three months (90 days) to discharge the mud once (sucked or dehydrated into mud cake by a manure truck for transportation). In addition to conventional high-altitude exhaust, the deodorization method of the buried domestic sewage treatment equipment is equipped with soil deodorization measures. The whole sewage treatment technology system of Weifang Yuanhang Environmental Protection is equipped with a fully automatic electrical control system and equipment fault alarm system, which is safe and reliable in operation, and generally does not need to be managed by people, but only needs to maintain and maintain the equipment in a timely manner.
The establishment of beautiful villages is a major measure to promote the scientific development of rural economy, improve the quality of life of farmers, accelerate the process of urban-rural integration, and build a happy countryside, and is the main starting point for promoting the construction of new countryside and ecological civilization. Fully implement the work deployment of "building happy villages and creating beautiful villages", adhere to the close combination of the construction of beautiful villages with industrial development, farmers' income increase and people's livelihood improvement, and comprehensively build beautiful villages suitable for living, working and traveling, improve the quality of life of urban and rural residents, promote ecological civilization and prompt the happiness of the masses in accordance with the goals and requirements of scientific planning and layout, clean and tidy environment, entrepreneurship and income, and rural civilization and physical and mental beauty.
