English Abstract
Wastewater treatment plant at Beit Lahia and its partially treated effluent lake are considered the primary sources of pollution for the ground water and ambient environment.
From February to May 2005, Field and laboratory tests were conducted and historical operating data were evaluated to assess the system performance in term of removal efficiency for the hybrid lagoon system.
This study attempts to distinguish the factors leading to the inadequate performance of the BLWWTP in removing organic matter and nitrogen.
The efficiencies of the different stages of the treatment and the global performance have been compared.
Collection and analysis of available historical data revealed a constantly decreasing removal of biochemical oxygen demand (BOD5), chemical oxygen demand (COD), suspended solids (SS), and fecal coliform (FC).
Analysis of data showed that the lagoon system removed 87 %. 13 %, 16 %, 20 %, 60 5, 57 % and 94.7 % of the influent TSS, BOD5, COD, TKN, NH3, PO4 and FC respectively with an effluent concentration of 39 mg / L, 178 mg / L, 72 mg / L, 84 mg / L, 72 mg / L, 5.5 mg / L, and 2.04E+05.
The decreasing removal of pollutants appeared to be caused by increased hydraulic and organic load that exceeds treatment plant capacity, incorrect design that lead to inefficient hydrodynamics, and inadequate operation.
Over hydraulic and organic loadings, limitation of Oxygen supply and unavailability of DO, inadequate design of plant geometry and high facultative and maturation ponds depth are the main factors leading to inadequate treatment system performance.
The study present suggestions like repositioning of inlets and outlets and / or adding baffles, micro-screen, and chlorination unit which can be introduced as short and simple solutions to overcome and improve partially the inefficiencies and poor treatment plant performance.
