Many netizens in consulting about sewage treatment equipment production company today small make up on the Internet to find an article about this website introduces sewage treatment equipment production company's related information, please follow look small make up sewage treatment equipment is mainly used for sewage and similar industrial organic wastewater treatment
, the main processing method is used at present relatively mature biochemical treatment technology -
Biological contact oxidation, design calculation is designed according to the general sewage water quality, water quality by the BOD5 an average of 200 mg/L, the effluent BOD5 was 200 mg/L design consulting industry sewage into the equipment on Settings - 15063679196 weeks
Adjust pool, to adjust the sewage water quality, water quantity, effective retention time is commonly 4 to adjust the pool
8 hours, adjusting pool inlet grille area, large particles which in sewage of elam sundry to ensure normal operation of the pump (
Automatic grille: adjustment in the pool water from the pump to grid, grid is used to block tiny floater and suspended particles in wastewater, block load down the dirt with the grille harrow automatically into the sewage pool, sewage into the subsequent process, the grating as equipment imported from Japan, has good separation effect,
Grid gap 5 mm to 10 mm)
In addition to dirt, difficult to jam, automatically the advantages of long service life,
Anaerobic pool, anoxic setting for denitrification process, after grille separation of sewage flow into the anaerobic pool and touch the reflow nitrifying liquid mixture, place NZP - lack of oxygen in the pool
11 type packing as A carrier of denitrifying bacteria, packing of nitrogen, phosphorus and sulphur whereabouts effect is good, stay for 2 hours with the combination of sludge in the process of renewal of pool forming method of A/O process, so as to achieve the aim of dephosphorization and denitrification,
Level 3 biological contact oxidation pool, with a total and 6 hours, before the NZP - 2
Type 1 packing, the packing is very superior in river, the third the NZP -
11 type packing, the packing is bigger than surface area, processing load up to 14 kgbod/m3.
D is generally the sewage treatment equipment production company is 5 -
10 times, biochemical pool according to the actual situation: dental sewage treatment equipment can use microporous aeration or jetting aerator or centrifugal aerator, wastewater in the biochemical pool cycle, fully and filler on the biofilm and organic matter degradation rapidly, sewage wastewater treatment equipment in the domestic wastewater, food processing and paper and other industrial waste water, contain carbohydrates, protein, oil, lignin and other organic substances.
These substances to suspended or dissolved state exists in sewage, can be decomposed by microbial biochemical effect.
Need to consume oxygen in the process of its decomposition, and thus is called oxygen contamination.
These pollutants can cause the water dissolved oxygen decrease, affect the growth of fish and other aquatic organisms.
After the water dissolved oxygen depletion, anaerobic decomposition of organic matter, produce the bad smell, such as hydrogen sulfide, ammonia and mercaptan worsen water quality further.
Composition of organic matter in water is very complex, oxygen concentration of organic matter per unit volume of water is commonly used oxygen consumption substances in the process of decomposition of biochemical oxygen, said that by biochemical oxygen demand (
General use 20 ℃, biochemical oxygen demand (five days
Sources of plant nutrients is wide, quantity is big, sewage (
Organic matter, detergent)
, agriculture (
Chemical fertilizer, farm manure)
, industrial waste water, waste, etc.
About 50 g per person per day into nitrogen in wastewater.
The sewage of phosphorus mainly comes from washing wastewater, and applied into the fields of chemical fertilizer with 50% ~ 80% flowing into rivers, lakes and underground water.
Phosphorus and nitrogen in natural water bodies (
Especially the phosphorus)
Content to a certain extent is to control the growth of plankton.
When a large number of nitrogen and phosphorus plant nutrients after discharged into water body, prompting some biological (
Such as algae)
Sharp reproduction growth, growth cycle shorter.
Algae and other plankton die by aerobic biological decomposition, depleting the dissolved oxygen in the water, or by anaerobic microbe decomposition, continuously produce the gas such as hydrogen sulfide, make water quality deterioration, killing a large number of fish and other aquatic organisms.
Algae and other plankton residue in the process of decay, and the biological need of nitrogen, phosphorus and other nutrients released into the water, algae and other creatures use for the new generation.
Therefore, after the eutrophication of water body, even to cut off the outside sources of nutrients, it is also hard to self-purification and return to normal levels.
Eutrophic water body is serious, some lakes can be numerous plants and its debris silting up, become a swamp even dry sewage processing complete sets of equipment.
Local sea area can be turned into a 'dead', or 'red tides.
Life in the ocean with all kinds of aquatic animals and plants.
Biological and water, biology and biological is a complicated matter and energy exchange between, from the number of kept a dynamic balance.
But under the influence of human activity, the destruction of the balance
