Description

River drain treatment facility

Technical Field

The utility model relates to a drain intensive processing technology field, concretely relates to river drain treatment facility.

Background

Along with the continuous acceleration of the urbanization and industrialization process, the urban river ecological system bears more and more pressure, the problem of river wastewater pollution is increasingly prominent, and a lot of researches are made on scholars at home and abroad. The common reasons for the problem of river wastewater pollution mainly include: 1) the domestic sewage is directly discharged into a river channel without being treated or not reaching the standard; 2) directly discharging the industrial sewage to a river channel; 3) pollutants caused by rainfall: in the early stage of rainfall, pollutants on a large amount of earth surfaces flow into the rainwater pipe network along with surface runoff in the early stage of rainfall, and then the pollutants deposited in the rainwater pipe network are carried and finally discharged into a water body, so that the pollution to a river channel is formed.

River pollution is mainly caused by a large amount of pollutants entering a water body in a short time, source control and sewage interception are the first step of river treatment and the most critical step, but municipal sewage interception is a difficult and time-consuming project, sewage interception planning of a plurality of areas, particularly urban old cities and suburbs, is difficult to implement, and comprehensive sewage interception of lakes is difficult to realize in a short time. Therefore, the pollution of the river channel is treated, a sewage draining exit without sewage interception needs to be treated to a certain extent, the influence of sewage drained from the sewage draining exit on the water quality of the river channel is eliminated or reduced, and effective implementation of other follow-up repairing means is ensured. Therefore, sewage treatment equipment is set along two banks of the river channel in order to treat sewage at the sewage discharge outlet of the urban river channel. However, the current method for processing by the equipment has the following disadvantages: the equipment and the process are not simple and easy, the investment is large, the land-buried equipment or the equipment arranged on the shore occupies large area, and the operation cost is higher.

The technology for treating the sewage draining exit in the current river course treatment also comprises the steps of separating sewage drained from the sewage draining exit from river course water by using a waterproof enclosure around the sewage draining exit, planting emergent aquatic plants and phytoplankton in the enclosure, and hanging microorganism fillers, wherein the measures have the following defects: 1) the enclosure cannot well separate the sewage from the river water, and the sewage still flows into the river to pollute the water body; 2) the sewage discharged from the sewage outlet can inhibit the growth of plants and even cause the death of the plants, so that the plants can not play a role in purifying the sewage; 3) the sewage outlet is likely to mix rain and sewage, so that the sewage discharge flow is large in the rainy period, and the pollution to the river channel is serious;

therefore, in order to solve the technical problem that exists, the utility model provides a river course drain treatment facility, equipment is simple, carry out the normal position processing to sewage in can putting into the river course, do not need to bury or place at the bank, the equipment size can be according to the water yield design size of drain, equipment area is little, the running cost is low, effectively reduce because of the great phenomenon that leads to the dirty mixed flow of rain to the river course to pollute, drop wetland group not only can high-efficient treatment sewage moreover, can also design according to the revetment, be used for beautifying river course ecological environment.
