Sewage Treatment

Integrated mbr membrane bioreactor sewage water treatment equipment for hospital restaurant hotel

Package wastewater treatment plant , Sewage Treatment Plant reusing for irrigation which adopts the advanced Biological technology and the company’s scientific research and engineering practice result, it can effectively remove BOD5,COD and NH3-N.


    Equipment introduction

    The device is characterized by the stable performance, effective treatment, economical investment, automatic operation, convenience of maintenance and small occupying space. There is no need for construction, neither heating and heat preservation.The surface can be used as green land or square land.It also can be placed on ground based on client's requirement. As the most efficient sewage treatment device, it is widely used in treating the sewage in the area of senior hotels, village districts and residential districts, industrials, resorts etc. The sewage water after treatment would meet the national emission standards or can be used to irrigation based on clients' requirement of water standards.



    (1) Hotel, restaurant, sanatorium, hospital, school,apartments, commercial establishments effulent treatment;
    (2) Residence community, villa district, village, town effulent treatment;
    (3) Station, airport, seaport and dock effulent treatment;
    (4) Factory, mine, army, beauty spot effulent treatment;
    (5) All kinds of industrial sewage similar to the living domestic effulent, etc


    Work Process

    The sewage enters the grid well first, and after removing the particulate matter from the grille, it enters the regulating tank,adjusts the water quality and quantity, and then is pumped to the primary sedimentation tank by the lift pump. The wastewater flows to the Class A biological contact oxidation tank for acidification hydrolysis and nitrification. Denitrification, reduce the concentration of organic matter, remove part of ammonia nitrogen, and then enter the O-level biological contact oxidation tank for aerobic biochemical reaction. Most of the organic pollutants are degraded by biooxidation, and the effluent flows to the secondary sedimentation tank for solid-liquid treatment. After separation, the supernatant of the sedimentation tank flows into the clear water tank, and the disinfection equipment is used to kill the harmful bacteria in the water and reach the standard discharge.


    Part Introduce

    1. Hydrolysis acidification tank. The retention of wastewater in the hydrolysis tank has the function of anaerobic fermentation, which can further improve and improve the biodegradability of wastewater, improve the follow-up biochemical reaction rate, shorten the biochemical reaction time, reduce energy consumption and operation cost.  
    2. The water from the contact oxidation tank hydrolytic acidification tank flows to the oxidation tank for biochemical treatment. The oxidation tank is divided into two levels. Most of the organic matter in the raw sewage is degraded and purified here. The aerobic bacteria take the filler as the carrier and use the organic matter in the sewage as the food to decompose the organic matter in the sewage into inorganic ones, so as to achieve the purpose of purification. The survival of aerobic bacteria must have enough oxygen, that is, there is enough dissolved oxygen in sewage to achieve the purpose of biochemical treatment.
    3. After being treated by biological contact oxidation tank, the effluent from the sedimentation tank flows into the sedimentation tank by itself to further remove the detached biofilm and some organic and inorganic small particles. The sedimentation tank is based on the principle of gravity. When the sewage containing suspended solids flows from the bottom to the top, the matter is precipitated by gravity. The effluent after sedimentation in sedimentation tank is more clear and transparent. The lower part is equipped with a conical sedimentation area and a sludge lifting device, and the precipitated sludge is lifted to the sludge aerobic digestion tank by air lift.  
    4. The excess sludge discharged from the sedimentation tank of sludge aerobic digestion tank is digested and stabilized in the sludge aerobic digestion tank to reduce the volume of sludge and improve the stability of sludge. The amount of sludge after aerobic digestion is small, so the suction truck can be used to extend from the inspection hole of the sludge tank to the bottom of the sludge tank for suction, and then it can be transported out (cleaning once half a year).
