Shandong Tianlang Environmental Protection Rural Wastewater Treatment Project in Weilou Village, Jining City, Shandong Province

In order to build a beautiful village, Shandong Tianlang Environmental Protection has been in action!

　　The problem of rural domestic sewage pollution has become a problem that cannot be ignored and urgently needs to be resolved. Rural domestic sewage is a general term for sewage generated by rural residents in the process of living and family farming.

　　Rural domestic sewage includes kitchen waste water (water for washing rice, water, etc.), laundry, bath and toilet sewage, domestic storage of poultry manure, and wastewater. Compared with urban domestic sewage, rural domestic sewage has its own characteristics in terms of emission point distribution, emission amount, pollutant concentration and resource demand.。

　　The rural domestic sewage treatment equipment adopts the internationally mature biological treatment process, adopts the underground integrated domestic sewage treatment equipment, and based on the experience of the domestic and international sewage treatment equipment, combined with its own scientific research results and engineering practice, designed a The organic wastewater treatment device can be buried and set up to remove BOD5, COD and NH3-N. The technical performance is stable and reliable, the treatment effect is good, and the operation cost is low.

Buried integrated sewage equipment features:

1. The whole set of equipment can be buried in the ground. The surface above the equipment can be used as greening or other land. It does not need to build houses, heating, and heat preservation. It can also be placed on the ground and has a relatively small footprint.

2. The secondary biological contact oxidation treatment process adopts push-flow biological contact oxidation, and its treatment effect is better than the complete mixed or two-stage series fully mixed biological contact oxidation tank. Compared with the activated sludge tank, it has small volume, strong adaptability to water quality, good impact load resistance, stable effluent quality and no sludge expansion. The membrane adopts a membrane aerator and a novel elastic three-dimensional filler, which has a large specific surface area, microbes are easy to hang the membrane, and the membrane is removed. Under the same organic matter load condition, the organic matter removal rate is high, and the solubility of oxygen in the air in water can be improved.
