Artificial ecological waste water treating device

Abstract

The artificial ecological waste water treating apparatus includes preliminary sedimentation tank, water storing tank, aerating biofilter, anoxia tank, plant ditch and biological pond communicated successively. The aerating biofilter has quartzite layer, steel slag layer, zeolite layer and turf layer set from bottom to top, water pipes with water outlet holes and air pipes with air outlet holes in the bottom, and grown heavy metal enriching plant. The anoxia tank has longitudinal partitions with gap remained between partition and the bottom of the tank, filled haydites and cultivated flower in the float bed. The plant ditch has longitudinal flaps for S-shaped flow of water, floated plant bed. The biological pond has nitrogen fixing floating plant. The artificial ecological waste water treating apparatus can eliminate nitride, phosphide, heavy metals and hard-to-degrade organic waste water as well as harmful bacteria.

Description

technical field [0001] The invention relates to a waste water treatment device, in particular to an artificial ecological waste water treatment device. Background technique [0002] The existing artificial ecological wastewater treatment, mainly wetlands and biological ponds, has a single species, and has failed to realize the optimal combination of plants for the gradual removal of pollutants. At the same time, there is no strengthening of microorganisms in the pre-treatment of sewage, resulting in a single sewage treatment function. , The treatment efficiency is low, the floor area is large, and it is greatly affected by the seasons, and sometimes the effluent water quality cannot meet the requirements. [0003] Most of the existing sewage is mixed sewage containing various pollutants, especially the sewage containing relatively high heavy metal ions has a strong poisonous effect on general plants, and a single artificial ecology is increasingly unsuitable for the treatmen...
