Environment engineering sewage purification treatment equipment

Abstract

The invention discloses environment engineering sewage purification treatment equipment. Sewage is collected and gathered into a main tube, and is firstly fed into a grating septic tank, and sewage after grating baffle treatment flows into a water quantity and quality adjusting tank for water quantity adjustment and water quality homogenization; three-dimensional elastic packing is mounted in a hydrolytic acidification reaction tank, and then the number of microorganisms in a unit volume can be increased; under the action of a great amount of hydrolysis bacteria and acidification bacterial, macromolecule degradation-refectory pollutants can be hydrolyzed into micro molecule easily degraded substances, furthermore the biodegradability of sewage is improved, and a base is made for later treatment processes; an effluent flows into an A / O biochemical pool and is reduced into C, N and O at molecular states; the effluent flows into an internal MRB (membrane bioreactor), and filtrate is gathered into a sterilization tank through an MRB membrane component water collection tube; residual sludge is discharged into the septic tank and is sucked and transported out by a fecal suction truck atregular time; a waste gas treatment device is adopted to deodorize and discharge waste gases into upper air, a high sewage treatment efficiency is achieved, up-to-standard emission of waste gases andstrong harmless sewage treatment capabilities can be achieved.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to sewage purification treatment equipment for environmental engineering. Background technique [0002] A septic tank is a small sewage treatment system that includes a pool and a septic system. When the sewage enters the pool, the bacteria will decompose the sewage anaerobically, and will reduce the volume of solid waste, and then discharge it after sedimentation, and the degree of water pollution will be reduced. The earliest septic tank originated in Europe in the 19th century. It has a history of more than 100 years. The initial purpose of setting up septic tanks in urban living areas is to collect fertilizers. With the progress of urbanization and the intensification of environmental pollution, septic tanks have played an active role in protecting water bodies. Nowadays, in many big cities in my country, the role of septic tanks in providing fertilizer for agricultural product...

AI Technical Summary

Problems solved by technology

[0006] The existing sewage treatment grid septic tank is relatively expensive, which is unaffordable for ordinary small enterprises, and the sewage treatment is not thorough, which leads to further treatment and increases additional costs; the scope of application is relatively narrow, and it cannot be widely used, and the sewage The treatment process is complicated and difficult to operate. Insufficient treatment is directly discharged, which leads to further pollution; the sewage treatment grid septic tank cannot be carried out continuously, and multiple machines are required to work together, which is troublesome

[0007] The existing water quantity and quality adjustment pools have the following deficiencies: firstly, the sewage treatment method is single, and the treatment effect is poor; Low and increase the cost of use; third: inconvenient manipulation and use

[0008] The existing hydrolytic acidification reaction tank has the following deficiencies; one: the suspension filler of the existing hydrolysis acidification reaction tank is easy to cause the anaerobic biofilm to fall off when the water fluctuates greatly, which affects the hydrolysis and acidification effect; The residence time is longer, and the efficiency needs to be improved; the third: complex pretreatment work is required, and the process is broken

[0009] The existing MBR membrane bioreactors have the following deficiencies: first: the sewage cannot be treated quickly; second: the filtering effect is poor; third: the impurities in the sewage cannot be filtered out during the treatment process, resulting in easy equipment jam

[0010] The existing exhaust gas treatment devices have the following deficiencies: first: the particulate pollutants contained in the exhaust gas cannot be filtered; second: the purification effect is poor and the work efficiency is low; third: the floor area is large and the labor intensity is high
