150 regiments of farm wastewater treatment, how to deal with the sewage of the farm

For farm wastewater treatment, it is recommended to lay a professional wastewater discharge pipeline in the farm, and then build a wastewater discharge concentration pool around the farm, that is, the wastewater treatment tank, and then purchase the corresponding wastewater treatment equipment, such as air compressors, ozone generators, filters, etc.!

No matter what system or comprehensive measures are used to treat livestock and poultry farm wastewater, it must first be separated from solid and liquid, which is an indispensable process link, and its importance and significance mainly lie in:

First of all, the solid suspended solids content in the wastewater discharged from the general farm is very high, up to 160,000mg L, and the corresponding organic matter content is also very high, and the pollutant load of the liquid part can be greatly reduced through solid-liquid separation;

Secondly, through solid-liquid separation, it can prevent larger solids from entering the subsequent treatment process, and prevent equipment from being blocked and damaged.

In addition, solid-liquid separation prior to anaerobic digestion can increase the reliability of anaerobic digestion operations, reduce the size of the anaerobic reactor and the required residence time, reduce facility investment, and improve COD removal efficiency.

Solid-liquid separation technology generally includes: sieving, centrifugation, filtration, flotation, sedimentation, sedimentation, flocculation and other processes. At present, China has mature solid-liquid separation technology and corresponding equipment, and its equipment types mainly include screen type, horizontal centrifuge, filter press, hydrocyclone, rotary conical screen and centrifugal disc separator.

It's all, integration can't deal with aquaculture sewage at all.

Using microorganisms, you can transform any water with different levels of pollution into the water quality you need, and that's what we do.

Integrated aquaculture sewage bai water treatment equipment adopts du

Biochemical treatment work.

Zhi art, high processing efficiency, effective dao

The removal of various organic matter in the sewage in the breeding is carried out, so that the effluent meets the "Livestock and Poultry Breeding Pollutant Discharge Standards". The equipment enables the sewage treatment of the farm to meet the discharge standard, and is the standard equipment approved by the Environmental Protection Bureau.

Second, the introduction of aquaculture sewage treatment process:

The main process commonly used in aquaculture sewage treatment equipment is "hydrolysis acidification tank + primary contact oxidation pond + anoxic pond + secondary contact oxidation pond".

Hydrolysis and acidification tank: The metabolic action of anaerobic bacteria is used to decompose organic matter into small molecule organic matter, and at the same time reduce the load of subsequent treatment structures.

Primary contact oxidation tank: The metabolic effect of aerobic microorganisms is used to decompose organic pollutants in wastewater into low-energy sludge such as carbon dioxide and water to stabilize them, and at the same time, the metabolism of nitrifying bacteria is used to convert ammonia nitrogen into nitrate.

Anoxic Pond: Using the metabolism of denitrifying bacteria, nitrate is converted into nitrogen to stabilize it, and then ammonia nitrogen in wastewater is removed.

Secondary Biological Contact Oxidation Tank: Further removal of organic matter from wastewater.

The most important thing is to reduce the organic matter of sewage, first use the breeding ammonia egg enzyme experiment to see the treatment effect, and then decide to design and ordinary sewage equipment. After the pretreatment of ammonia egg enzyme, it can generally be treated in the earth, and at the same time eliminate the odor of ammonia, decompose most of the organic matter, and the treatment is not thorough, and the sewage treatment equipment is small.

The buried sewage treatment equipment is a modular sewage biological treatment equipment, which is a sewage biological treatment system with biofilm as the main body of purification, which gives full play to the characteristics of large biological density, strong pollution resistance, low power consumption, stable operation and convenient maintenance of biofilm reactors such as anaerobic biological filter and contact oxidation bed, which makes the system have a wide application prospect and promotion value.

Now the sewage treatment solution of the farm, first according to the actual situation of the on-site solution, and then according to the index of C o D and ammonia nitrogen in the sewage, from the pig house to the storage tank, biochemical treatment, and then through physical treatment (equipment treatment) to meet the discharge standard.

Is there a treatment process?

Biochemical pool aeration is required.

Pool, not to calculate the area, but to calculate the volume! Or, you need to at least know the length, width, and height of the pool, the total area of the 5 surfaces you need to treat, and the degree of contamination of these surfaces varies from the hail process you need to treat! If it is a general treatment, an area of 2 5 yuan square is enough, but if special treatment is required, the cost will of course not be the same!

This is related to the method of sewage treatment, the price of different equipment is different, and the treatment effect is also different.

The buried aquaculture sewage treatment equipment adopts the international advanced biological treatment technology, which 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 second-stage biological contact oxidation treatment process adopts push-flow biological contact oxidation, and its treatment effect is better than that of fully mixed or two-stage series fully mixed biological contact oxidation tank.

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 new elastic three-dimensional filler is used in the pool, the surface area is large, the microorganisms are easy to hang the film, and the film is removed, and the removal rate of organic matter is high under the same organic matter loading conditions, 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 equipment processing system 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 special personnel to manage it at ordinary times, and only needs to maintain and maintain the equipment in a timely manner.

The scope of application of buried domestic sewage treatment device.

hotels, restaurants, nursing homes, hospitals; residential quarters, villages, market towns; stations, airports, seaports, terminals, ships; factories, mines, tourist spots, scenic spots; Various types of industrial organic wastewater similar to domestic sewage.

According to the literature, oxidizing 1kg of BOD requires the consumption of 1kg of oxygen, so the landlord can calculate it. You can also go to the environmental protection general to ask.
