Description

An underground integrated sewage treatment device

technical field

The utility model relates to the technical field of sewage treatment, in particular to an underground sewage treatment device.

Background technique

Buried integrated equipment is an integrated equipment that uses membrane bioreactor to treat sewage by combining activated sludge method and biofilm method. It uses anaerobic bacteria, aerobic bacteria, facultative bacteria, etc. The bacteria strains degrade and remove the toxic and harmful organic matter in the sewage, which has reached the sewage discharge standard. Its advantages: good effluent quality, low operating cost, strong impact resistance of the system, less sludge, high degree of automation, small footprint, and easy integrated operation. Because it is buried in the ground, the ground covering soil can be planted for greening or used as a square land, so there is no need to take thermal insulation and antifreeze measures. It is one of the hotspots in the field of sewage treatment and has broad application prospects.

With the development of my country's economy and the advancement of urbanization, the shortage of water resources and the aggravation of water pollution have become increasingly severe. The requirements for sewage treatment and reuse have become increasingly urgent, and the control of pollutant discharge has become more and more stringent. The traditional sewage treatment process has prominent problems such as high pipeline network investment, large floor area, and long construction period, which seriously restricts the sewage treatment rate and COD emission reduction. In this case, the buried integrated sewage treatment equipment as a This simple and effective sewage treatment equipment is more and more widely used.

The traditional buried integrated sewage treatment equipment adopts anaerobic and aerobic methods and consists of six parts: primary sedimentation tank, anaerobic tank, aerobic tank, sludge tank, disinfection tank and fan. It is suitable for organic industrial sewage and domestic sewage similar to domestic sewage in food, slaughtering, brewing, printing and dyeing industries.

The current anaerobic and aerobic method does not have an independent sludge return system, so it cannot cultivate sludge with unique functions, and the degradation rate of refractory substances is low; in order to improve the denitrification efficiency, the internal circulation ratio must be increased. Thus increased operating costs. In addition, the internal circulation fluid comes from the aeration tank, which contains a certain amount of DO, which makes it difficult to maintain an ideal anoxic state in the A section, which affects the denitrification effect, and the denitrification rate is difficult to reach 90%. The existing buried equipment has problems such as poor stability, low sewage treatment efficiency, and large floor area.
