Abstract

Przedmiotem zgłoszenia jest sposób otrzymywania koncentratu z komunalnych ścieków oczyszczonych do wykorzystania jako nawóz dla roślin polegający na przeprowadzeniu filtracji, charakteryzujący się tym, że w pierwszym etapie oczyszcza się z zawiesiny ogólnej oraz mikroorganizmów komunalne ścieki oczyszczone w procesie mikrofiltracji lub ultrafiltracji przy ciśnieniu co najmniej 2 bary, następnie w drugim etapie uzyskany permeat z mikrofiltracji lub ultrafiltracji zagęszcza się w procesie nanofiltracji w cyrkulacji przy ciśnieniu co najmniej 8 barów aż do produkcji pierwszego koncentratu stanowiącego pierwszy retentat i wody oczyszczonej, zaś otrzymany retentat z nanofiltracji zagęszcza się w trzecim etapie polegającym na nanofiltracji w cyrkulacji przy ciśnieniu co najmniej 8 barów aż do produkcji drugiego koncentratu stanowiącego retentat właściwy. Zgłoszenie obejmuje także nawóz dla roślin otrzymany z komunalnych ścieków oczyszczonych, znamienny tym, że stanowi roztwór wodny otrzymanego według opisanej metody w zastrzeżeniu 1 - 4 koncentratu o stężeniu 20 - 100% zawierający związki organiczne, w tym kwasy humusowe oraz jony wapnia i magnezu, przy czym zawiera kwasy humusowe o stężeniu co najmniej 29,5 mg/L, jony magnezu, wapnia, siarczanów, związków fosforu i azotu o sumarycznym stężeniu co najmniej 2135 mg/L. Przedmiotem zgłoszenia jest też układ do otrzymania koncentratu z komunalnych ścieków oczyszczanych.The subject of the application is a method of obtaining a concentrate from purified municipal wastewater for use as a fertilizer for plants, consisting of filtration, characterized by the fact that in the first stage municipal wastewater treated by microfiltration or ultrafiltration at a pressure of at least 2 bar is purified from the total suspension and microorganisms. , then in the second stage the obtained microfiltration or ultrafiltration permeate is concentrated in the nanofiltration process in circulation at a pressure of at least 8 bar until the production of the first concentrate constituting the first retentate and purified water, and the obtained nanofiltration retentate is concentrated in the third stage consisting of nanofiltration in circulation at a pressure of at least 8 bar until the second concentrate is produced, constituting the retentate. The application also covers fertilizer for plants obtained from municipal treated sewage, characterized in that it is an aqueous solution of the concentrate obtained according to the method described in claim 1-4 with a concentration of 20-100% containing organic compounds, including humic acids and calcium and magnesium ions, with which contains humic acids with a concentration of at least 29.5 mg / L, ions of magnesium, calcium, sulphates, phosphorus and nitrogen compounds with a total concentration of at least 2135 mg / L. The subject of the notification is also a system for obtaining concentrate from municipal treated sewage.
