Sewage purifying treatment equipment for water conservancy and hydropower environment engineering

Abstract

The invention discloses sewage purifying treatment equipment for water conservancy and hydropower environment engineering. Sewage is collected, is then converged in a main pipe and firstly enters a grid-type septic tank, and the sewage intercepted by grids automatically flows into a water quantity and water quality adjusting tank for water quantity adjustment and water quality homogenization; a three-dimensional elastic filler is mounted inside a hydrolyzing and acidifying reaction tank so as to increase the number of microorganisms per unit volume, and under the action of a large number of hydrolyzing bacteria and acidifying bacteria, high molecular non-degradable pollutants are hydrolyzed into easily-degradable small molecular substances, so that the biodegradability of the sewage is improved and a foundation is laid for a subsequent treatment technology; effluent water automatically flows into an A/O biochemical tank and is reduced into C, N and O in molecular states; effluent waterautomatically flows into a built-in MRB membrane bioreaction tank, and a filtrate flows through a water collecting pipe of an MRB membrane assembly and is converged into a disinfection tank; remaining sludge is discharged into the septic tank, regularly sucked by a fecal suction truck, externally transported and disposed; waste gas is deodorized by a waste gas treatment device and emitted at a high altitude. The sewage treatment efficiency is high, waste gas emission is up to the standard, and the harmless wastewater treatment performance is strong.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to sewage purification treatment equipment for water conservancy and hydropower environmental engineering. Background technique [0002] A septic tank is a small sewage treatment system that includes a pool and a septic system. When the sewage enters the pool, the bacteria will decompose the sewage anaerobically, and will reduce the volume of solid waste, and then discharge it after sedimentation, and the degree of water pollution will be reduced. The earliest septic tank originated in Europe in the 19th century. It has a history of more than 100 years. The initial purpose of setting up septic tanks in urban living areas is to collect fertilizers. With the progress of urbanization and the intensification of environmental pollution, septic tanks have played an active role in protecting water bodies. Nowadays, in many big cities in my country, the role of septic tanks in providing fe...
