Price of micro sewage treatment equipment——Design points:

AThe anaerobic hydrolysis tank adopts the form of an upflow anaerobic sludge bed reactor, with a designed hydraulic retention time of2~4Hour. The lower part of the anaerobic tank is the sludge bed area, and the thickness of the sludge bed is usually controlled within1~1.2MBetween them, the inlet system can adopt a pulse inlet medium resistance water distribution system, with a water distribution ditch at the bottom to retain the sludge and prevent it from settling at the bottom, in a suspended state. The average concentration of sludge bed is30~35g/l,The sludge load is0.35~0.30kgCODcr/kg(ss).d.

BThe biological contact oxidation process is a wastewater treatment process that falls between the activated sludge method and the biofilm method. The pool is equipped with packing materials, and some microorganisms are fixed on the surface of the packing materials in the form of biofilms, while others grow in a flocculent suspension in the water. Therefore, it has the characteristics of both activated sludge process and biological filter. The aeration system can use a blast or jet aeration system (investment and operating costs must be considered during design). It is effective to divide the contact oxidation tank into two compartments for cultivating different advantageous strains of microorganisms. The effective hydraulic retention time of the first grid is2.5Hour, organic load is1.15kgBOD5/m3.dThe effective hydraulic retention time in the second grid is1.5Hour, organic load0.768kgBOD5/m3.d.A/OThe main characteristics of law are: strong adaptability; Resistance to impact load; High volume load; There is no sludge swelling; The amount of sludge discharged is very small; Has good denitrification effect. causeA/ODerived from lawA2/O、A3/OThe principle of sewage treatment process is similar.

Price of micro sewage treatment equipment——Structural principles and characteristics of pumps for integrated sewage treatment equipment

1)The structure of the pump for integrated sewage treatment equipment: The pump consists of three parts: motor, transmission box, and cylinder body.

The transmission box components are composed of a cam mechanism, a stroke adjustment mechanism, and a speed ratio worm gear mechanism;By rotating the adjustment handwheel to adjust the stroke of the tappet, the expansion and contraction distance of the diaphragm can be changed from the surface to achieve the purpose of changing the flow rate.

The cylinder components of the integrated sewage treatment equipment pump are composed of the pump head, suction valve group, discharge valve group, diaphragm base, and other diaphragm bases.

2)The working principle of the pump for integrated sewage treatment equipment is that the motor drives the worm through the coupling and reduces the speed of the worm wheel, causing the main shaft and eccentric rotation to rotate. The eccentric wheel drives the plunger to make reciprocating motion in the guide cylinder. The integrated sewage treatment equipment uses a pump together with a diaphragm, which gradually forms a vacuum in the pump chamber through the action of a one-way valve. The suction valve opens and sucks in liquid;When the diaphragm moves towards the dead center, the suction valve closes and the discharge valve opens, and the liquid is discharged under the push of the diaphragm. By adjusting the reciprocating stroke of the pump, a continuous pressure and quantitative discharge of liquid is formed.

3)The flow regulation characteristics of pumps used in integrated sewage treatment equipment: The flow regulation of pumps relies on rotating the adjustment handwheel to drive the adjustment screw to rotate, thereby changing the spacing between the tappets and changing the movement stroke of the diaphragm in the pump chamber to determine the flow rate. Adjust the scale of the handwheel to determine the travel of the diaphragm, with an accuracy of95%.

Price of micro sewage treatment equipment——The relationship between buried sewage treatment equipment and urban development

The development of cities and the increase in population have brought enormous pressure on sewage discharge!At present, most sewage treatment plants in China adopt above ground construction. However, with the continuous improvement of urbanization level and environmental requirements, the requirements for domestic sewage treatment equipment are also constantly increasing. For example, the noise, unpleasant odor, and land occupation of above ground sewage treatment projects will restrict the comprehensive development of cities.

Compared to the industrial wastewater treatment field, domestic wastewater treatment belongs to the government investment field with strong investment rigidity. How to improve urban wastewater treatment technology has always been an important issue in solving urban environmental problems. However, the location of sewage treatment plants has always been an important key issue in urban sewage discharge systems. Can geographic domestic sewage treatment equipment become a new development trend? Let's analyze this issue below.

Firstly, geographic sewage treatment equipment can save land resources. By making reasonable use of underground space, land resources can be saved and the serious shortage of land resources in some cities can be solved. Secondly, it plays a role in beautifying the planning and construction of the city. Geographic based domestic sewage treatment equipment can reduce noise pollution, air pollution, and other issues, reduce interference with surrounding residents, and have a better beautifying effect on the environment. Thirdly, from a long-term perspective, sewage treatment plants meet the requirements of the scientific development concept. Of course, it is important to improve the quality of geographic domestic sewage treatment equipment, otherwise the quality of buried domestic sewage treatment equipment will not meet the standard, and maintenance will be much more complex compared to surface domestic sewage treatment equipment!

Price of micro sewage treatment equipment——Preparation work before construction

1Construction conditions

(1)Before the installation of sewage treatment equipment, design and construction drawings or equipment technical documents should be provided, and reasonable arrangements should be made for temporary transportation roads, water sources, power sources, lighting facilities, main materials and machinery, labor, etc.
