Environment-friendly household sewage sludge and its manufacturing method |
| abstract |
The present invention relates to a method for producing environmentally friendly domestic sewage sludge, and more particularly, to a method for discharging environmentally friendly sewage sludge, which can be recycled. The pretreatment process is carried out in the treatment stage of the tank, but the sewage sludge is discharged after performing the pretreatment process to chemically and stably fix heavy metals and harmful organic substances in the waste water by using chelating agent and toxic adsorbent as pretreatment agents. The present invention relates to a method for producing environmentally friendly sewage sludge, which is characterized by obtaining a stabilized sewage sludge by preliminarily removing environmentally harmful substances from the sewage sludge. |
