2.Design Capacity:
According to the data provided by the owner, the sewage treatment station has two lines, one is acid and alkali waste water, the design treatment capacity is 2 m³/h; the other is chromium-containing sewage, and the design treatment capacity is 0.5 m3/h.. Considering the change of water quantity, the equipment has a certain margin, and the actual processing capacity is larger than the design capacity.

3.2  waste water regulating tank
 Both industrial wastewater and domestic sewage, water quality and quantity of water within 24 h fluctuate. This change is unfavorable to wastewater treatment equipment, especially biological treatment equipment, to perform its purification function normally, and may even cause damage. Similarly, for physicochemical treatment equipment, the greater the fluctuation of water quality and quantity, the more difficult the process parameters are to control, and the more unstable the treatment effect is; conversely, the smaller the fluctuation, the more stable the effect is. therefore, before the wastewater treatment system, a homogenized regulating tank should be set up to regulate the quantity of water and the water quality, so as to ensure the normal operation of the wastewater treatment, and to adjust the PH in the regulating tank to meet the requirements of the acidity and alkalinity of the subsequent process.

3.3   inclined tube precipitator
 Sedimentation is the process of removing suspended solids from wastewater by gravity settling principle, and the main treatment facility is sedimentation tank. the sedimentation tank is mainly to remove the suspended solids that can be settled suspended in the wastewater. the sedimentation tank before biochemical treatment is mainly to remove inorganic particles and part of organic matter. the sedimentation tank after biological treatment is mainly to remove microbial bodies. The integrated sedimentation device adopts inclined tube precipitator, which means the settling equipment with inclined tube packing in the sedimentation area, which is made according to the precipitation principle of removing fractional particles in the advection sedimentation tank. By adding inclined tube in the tank, reducing the hydraulic radius and increasing the wet cycle of the cross section of the pool, the flow rate can greatly reduce the Reynolds number at the same horizontal flow rate, thus reducing the storage flow and promoting precipitation. In addition, adding inclined plate can also shorten the precipitation distance, reduce the precipitation time and improve the sedimentation efficiency. the upper layer of clear water in the sedimentation tank enters the subsequent treatment unit through the overflow Weir, and the sludge settling enters the sludge hopper collection and management road and is discharged into the sludge thickening tank.

The PH of wastewater is unstable, set up PH on-line monitor, automatically adjust the PH value of wastewater, less than 6.5 when adding alkali, higher than 7.5 when adding acid. At the same time, sodium bisulfite and calcium oxide were added to the wastewater, and chromium ions, SS, oil and graphite were condensed into large flocs and removed by precipitation separation.

Functions: Removal of COD,chromium, SS silicone oil and graphite from waste water

3.4  Mechanical filters
 Automatic mechanical filter is suitable for industrial and mining enterprises and municipal water treatment equipment which require that the turbidity of filtered effluent generally be within 5 mg/L to meet the drinking water quality standards. It has good effect on removing suspended solids in industrial sewage. The water can pass through the filter layer in the pressure filter to make the water transparent.
 Mechanical filter also known as pressure filter is the pre-treatment of pure water preparation, water purification system is an important part of the material made of steel lining glue or stainless steel, because the filter filling medium is different, the use and role of different. Generally there are quartz sand filter, activated carbon filter. iron and manganese removal filter. Can be used separately or jointly depending on the situation
 The medium of multi-medium filter is quartz sand, anthracite and so on. The function is to filter out the mechanical impurities and organic matter of suspended matter and reduce the turbidity of water. The medium of activated carbon filter is activated carbon, which aims to adsorb and remove pigment, organic matter, residual chlorine, colloid and so on in water. The medium of manganese sand filter is manganese sand, which mainly removes divalent iron ions in water.
