The problem of leachate generated at municipal landfills, and the challenges its logistics disposal, are forcing search for new, environmentally friendly methods treatment, especially when it can be applied in situ. method that combines constructed wetland system with conventional activated sludge process, hereinafter referred to as Vegetation-Activated Sludge Process (V-ASP), may an interesting alternative, but still require research comprehensive evaluation. Therefore, this study aimed...

Air stripping is commonly used to remove the ammonia in multistage treatment systems for municipal landfill leachate (LFL). This paper proposes a novel approach combining process of with biological removal ammonia, based on simultaneous nitrification and denitrification (SND) single hybrid sequencing batch reactor (HSBR). To avoid accumulation free (N-FAN), shallow aeration system was raw LFL N-TAN level 1520 mg/L pH 9.24. The mean N-FAN efficiency 69% reaction rate 55 mg L−1 h−1 ammonium...

Application of sequencing batch reactors (SBR) for treatment leachate from old, stabilized landfills, could be still an economically viable solution, as far nitrogen removal is concerned. Very low amounts accesible organic compounds requires unconventional approach to technology. In this paper the authors proposed utilisation polyurethane (PU) foam various porosity a biomass carrier, hydraulic retention time (HRT) extended 2 days and temperature elevated 37°C, stimulate simultaneous...

ABSTRACT: The study focused on the problem of removing refractory substances from leachate treated by means activated sludge method and advanced oxidation process. Biological treatment was conducted in sequencing batch biofilm reactor. Biologically subject to further chemical with use Fenton reagent. permanent dosage H 2 O amounting mg·L −1 applied. Fe(II):H ratio 1:10, 1:5 1:3. allowed for 97% benzene only 20% ethylbenzene. There a 25% decrease concentration volatile organochlorine...

In this work, the semi-synthetic wastewater made of leachate derived from non-hazardous municipal waste landfill in Kozodrza (south-eastern Poland) and supplemented by ammonium, was treated hybrid SBRs to assess removal efficiency organic compounds, including humic substances dissolved fractions, depending on technological conditions.The layout variants concerned both volumetric proportions aerated anoxic zones (0.33 0.66) as well N/C ratio (0.1 0.2).It found that compounds (expressed COD,...

Dumping municipal waste is the least expensive and most commonly used method of disposing solid waste.However, there an alternative, two-in-one, solution: conversion to energy.Non-recyclable can be turned into heat, electric power or fuel using various processes, such as gasification, pyrolysis anaerobic fermentation.This how residual serve sustainable local source energy, additionally, contributing environmental protection and, a significant extent, energy supply security.

The amount of generated municipal waste depends not only on the population but also consumption patterns and economic welfare.The aim this paper was to present structure over years in European Union, Poland, Subcarpathian Voivodeship, Rzeszow.It has been assumed that SARS-CoV-2 pandemic, political action government, higher standard living society are factors influencing increase by households segregation.The analyses management system using official data collected published Statistics Poland...

Among the waste produced by municipal wastewater treatment plants, largest technological problem is caused excessive sludge, management of which consumes almost half costs entire installation.Regardless final disposal route, may be, for example, reclamation degraded areas, sludge derived from a plant should be firstly subjected to series processes aimed at: reducing its volume, improving selected physical properties, recovering energy, rot preventing (stabilization) or eliminating...

Tetrabromobisphenol-A (TBBPA) is a flame retardant widely used in the production of plastics, textiles, electronics, or electrical equipment.This compound was identified environmental samples and sewage sludge, thus its impact on biological processes wastewater treatment plants interesting.This work investigates advanced oxidation pretreatment TBBPA bisphenol-A (BPA) solutions toxicity to activated sludge.The highest efficiency these micro-pollutants' removals (expressed by chemical oxygen...

Abstract Short-rotation woody plants of the genus Paulownia are attracting more and attention as trees that produce biomass reduce concentration carbon dioxide in atmosphere. However, growing monoculture affect properties condition soil. One effects changes soil environment is population plant parasitic nematodes (PPN). The article presents information about PPN inhabiting root zone tomentosa plantation Poland. In this study, frequency density nematode populations samples from seven...

Gospodarka odpadami komunalnymi jest istotnym elementem zrównoważonego rozwoju. Obecność tych odpadów w środowisku może powodować szereg zagrożeń takich jak zanieczyszczenia wód powierzchniowych i podziemnych, powietrza ekosystemu glebowego, stanowią one również siedlisko żerowania owadów, ptaków gryzoni. Ulegają przemianom biochemicznym mogą oddziaływać na środowisko poprzez produkty rozkładu: dwutlenek węgla, siarkowodór, aldehydy, kwasy organiczne, metan inne związki. Mają więc wpływ...

In this studies the influence of dose and ratio chemical reagents (Fe 2+ H 2 O ) on efficiency COD removal changes BOD 5 /COD in landfill leachate was analysed.The molar Fe /H lower than 1 amounted to: 1:10, 1:5, 1:3, three research series with 1; 2.5 g/L concentration.A higher removing COD, therefore decrease effluent stated.The from 58.34% 0.5 g/L, 1:5) to 8.33% = 0.1 1:10), while ranged 62 77%.With equal 1:5 largest for each analysed doses.The lowest observed 1:3.
