Rural wastewater treatment equipment has its own characteristics, small footprint, easy to integrate. Not only has domestic sewage treatment, but also can be used for large-scale sewage treatment. As the core processing equipment, it is the better sewage treatment assistant at present, and the integrated sewage treatment equipment is cheap and cost-effective.
Purification tank rural sewage treatment equipment using improved A/O + filtration technology, equipped with advanced intelligent control system, short installation cycle, short commissioning time, low investment and operating costs, high treatment efficiency, pollution characteristics of the second.
China's rural sewage treatment status quo starting point is low, the market potential is huge, the starting point of the low main performance in two aspects. Firstly, the sewage treatment efficiency is low. In recent years, the treatment rate of rural domestic sewage treatment equipment is low. In the built equipment, there is not much normal operation. According to relevant statistics, the normal operation of the rural sewage treatment equipment built in China may be less, which means that the normal operation of the rural sewage treatment equipment built in China may be less, and most of the processing equipment will be modified or postponed in the future.
On the other hand, the starting point is lower, on the other hand, the national environmental protection policy requirements, including the life of the rural population of the environment, more and more high, the government's investment in the village sewage field is increasing, which means that the domestic village wastewater treatment has a huge market potential, rural wastewater treatment is recognised by the industry as a blue ocean after the water industry.
At present, the target discharge standard for most domestic sewage treatment processes in towns and cities is the primary B discharge standard, but in fact, even the primary B discharge standard does not meet all the targets. For example, CODcr and ammonia are easily met and total nitrogen and total phosphorus are usually not, a situation that may exist in the market based on low levels of effluent quality monitoring and under-investment in the country's towns and villages. Effluent indicators are usually only monitored for CODcr and ammonia. In addition, sewerage networks in towns and villages are generally poor. Groundwater, springs and rainwater mix into the sewerage network, leading to dilution of influent concentrations. However, as the country's environmental protection requirements become stricter and more attention and investment is being paid to village wastewater, this situation will be unsustainable, and it is imperative to improve the level of processing technology.
Food wastewater, including alcohol, beer, monosodium glutamate, starch, lactose, citric acid, vegetable processing and a variety of soft drinks process discharged during the sewage, if the sewage is not treated in a timely manner will cause great pollution of the environment.
Sewage characteristics: food industry wastewater is characterised by high content of organic matter and suspended solids, easy to corrupt, generally no major toxicity, water quality and water quality with seasonal changes, high concentration of sewage. Its harm is mainly to make the water body eutrophication, so as to cause the death of aquatic animals and fish, prompting the deposition of organic matter under the water to produce odour, deterioration of water quality, pollution of the environment.
Treatment: This type of sewage is proposed to use air-float anaerobic aerobic treatment as the main process, the first sewage into the grease trap adjustment pool, then pumped into the air-float pool to remove most of the insoluble impurities and oils and fats, and then into the anaerobic aerobic biological treatment, biochemical treatment of water to meet the tertiary standards for discharging into the urban sewerage network.
Food industry, including meat processing, aquatic processing, dairy processing, canning, brewing, sugar and many other industries, so the food industry wide range of raw materials, a wide variety of products, discharged effluent water, water quality varies greatly. The difference with other industrial wastewater is that food industry wastewater generally does not contain heavy metals, pesticides and other harmful substances, but its BOD, COD, etc. will generally be high. As most of the raw materials used in the food industry for the human body can digest organic substances, so the food industry sewage biochemistry is generally better.
